Résumé :

2008/2009
Alla base del lavoro di ricerca è stato posto un impianto metodologico a carattere multidisciplinare contrassegnato da un lato da un’analisi introduttiva teorico-geografica relativa alle tematiche inerenti il governo del territorio e del paesaggio in area protetta, dall’altro, da una fase di esame (connessa ad un ambito di indagine più strettamente cartografico – digitale) tesa a fare il punto sullo stato di avanzamento -a livello comunitario e nazionale- in merito al tema della costruzione di infrastrutture di dati spaziali, pubblicazione e condivisione di servizi legati al settore del Geographical Information System, con attenzione alla comunicazione degli elementi di natura ambientale (rintracciabili anche all’interno del contesto aree protette). Entrambe le panoramiche, arricchite al loro interno dalla descrizione del quadro normativo transcalare di riferimento, risultano necessarie ai fini della contestualizzazione e impostazione del lavoro e conducono ad una fase di screening in merito al tema comunicazione dei dati territoriali in ambiente webgis da parte degli enti italiani gestori delle aree protette, nello specifico parchi nazionali e regionali. Tali elementi teorici, legislativi e conoscitivi sono stati poi presi a riferimento nel corso della fase applicativa della ricerca con lo scopo di guidare e supportare i momenti che hanno condotto alla realizzazione di applicazioni dedicate all’area Parco del Conero facenti seguito ad una fase di survey sul campo, ad un’organizzata raccolta di dati territoriali (di base e di Piano del Parco) e successive fasi di analisi spaziale. Lo scopo è quello di supportare (grazie agli applicativi realizzati) le operazioni di gestione, studio e comunicazione territoriale che un Ente responsabile di un’area protetta si trova a dover definire e implementare alla luce delle tematiche considerate nel corso della sezione teorica. I risultati tangibili si incarnano nella creazione di un’architettura che partendo dal relational database, passando per il geodatabase e giungendo alle piattaforme webgis dinamiche e interattive funga da supporto ai processi di coordinamento, analisi e diffusione di selezionati elementi territoriali relativi al comprensorio Parco del Conero e al suo principale strumento di pianificazione (Piano del Parco) agevolando e supportando così sia processi gestionali e decisionali più “consapevoli”, sia percorsi informativi e partecipativi strutturati. Il corpus definitivo dell’elaborato è stato suddiviso in due parti distinte allo scopo di scandire i momenti dello studio e consentirne una più immediata lettura. Ciascuna si articola in tre capitoli. La prima parte, a cui si è assegnato il titolo “Governo del territorio e condivisione del dato informativo e cartografico. Scenari evolutivi verso lo sviluppo di dinamiche partecipative” esplicita al suo interno il quadro teorico, normativo e conoscitivo posto alla base della ricerca. - Nel corso del primo capitolo si è ritenuto opportuno introdurre brevemente alle recenti dinamiche che hanno interessato i concetti, le definizioni e gli aspetti normativi inerenti le tematiche relative al governo del territorio e del paesaggio in area protetta, più nel dettaglio di quello dei parchi naturali regionali in Italia e forme del paesaggio da tutelare. Un excursus che ha preso in esame gli scritti geografici nazionali e internazionali sul tema, facendo emergere posizioni eterogenee, in continua evoluzione e, comunque, oggi in linea con i recenti indirizzi di contesto sviluppati e approvati in ambito comunitario e convenientemente riletti alla scala nazionale. Il tutto ha la necessità di essere supportato da un’adeguata rappresentazione cartografico-tassonomica delle diverse tipologie, unità e categorie di paesaggio e parco. Principio, quello della classificazione, che caratterizza una delle fondamentali linee di dibattito, internazionale e nazionale sull’argomento. - Il secondo, attraverso un approccio che lega il mondo del Geographical Information System e le aree protette tramite il tema della pubblicazione e condivisione dei dati spaziali e ambientali, configura brevemente lo stato dell’arte nel contesto di realizzazione di infrastrutture ad essi dedicate, di implementazioni relative alla stesura dei metadati da indicare per set e serie di elementi territoriali, nonché servizi per i medesimi. Lo sguardo viene rivolto alle direttive, ai regolamenti e alle decisioni in ambito comunitario e alle trasposizioni delle stesse all’interno del contesto nazionale. - Nel terzo si inizia ad entrare nella parte del lavoro di ricerca caratterizzata da un’impronta più conoscitiva che teorico-normativa. Ci si spinge oltre il quadro concettuale e si cerca di capire, attraverso la realizzazione di uno screening sul tema della comunicazione e diffusione (da parte dei rispettivi enti gestori) dei più rilevanti dati territoriali relativi ai parchi nazionali e regionali italiani tramite piattaforme webgis, cosa nel nostro paese è stato fatto a favore della loro divulgazione e quali possono configurarsi come margini di miglioramento futuro. L’analisi è corredata da grafici e tabelle di dettaglio in relazione alle quali si espongono commenti relativi ai risultati ricavati nel corso dell’indagine -sia in valore assoluto che in valore percentuale-. Il capitolo funge da ponte tra la sezione teorica del lavoro e quella dedicata invece al caso di studio specifico. La seconda parte “Un’applicazione territoriale: il Parco del Conero. Da un’analisi geografica di contesto ad una di dettaglio attraverso tools gis-analyst. Database Management System e Web Service Application per la gestione e la comunicazione”, memore dell’indagine teorico-conoscitiva, è dedicata alla presentazione del caso applicato all’area protetta del Conero. Nel dettaglio: - all’interno del capitolo quarto si fornisce un inquadramento territoriale dell’area oggetto di esame tramite analisi condotte grazie a tools gis-analyst (ArcGis – ArcToolbox). Tale inquadramento viene arricchito dal rilievo sul campo della rete sentieristica interna al Parco del Conero in relazione alla quale si descrivono le modalità di acquisizione dei dati e le successive fasi di post-elaborazione. Il rilievo dei sentieri (reso necessario dal fatto che la rete era stata solo digitalizzata sulla carta) ha consentito di completare il quadro di analisi relativo alla viabilità pedonale interna all’area parco, ponendo l’accento non solo sulle caratteristiche di fruibilità turistico-paesaggistica che questa possiede, ma integrando i dati raccolti con quelli del Piano del Parco già a disposizione dell’Ente al fine di giungere alla realizzazione di modelli di analisi spaziale (ESRI Model Builder) da poter applicare in successive fasi di valutazione territoriale dell’area stessa o di programmazione concernente interventi puntuali da effettuarsi sulla rete sentieristica in relazione a tratti di percorso caratterizzati da elementi di criticità. Di tali modelli si sottolineano le caratteristiche di versatilità e adattabilità a qualsiasi tipologia di territorio, protetto e non, che risulti attraversato da sentieri, percorsi e itinerari turistico - culturali o di fruibilità paesaggistica e naturalistica. Il capitolo si conclude con la descrizione delle finalità di indagine e struttura dei modelli stessi. - Nel capitolo quinto i dati alfanumerici, quelli ricavati dalle survey della rete sentieristica, quelli di piano, nonché quelli riguardanti le fonti bibliografiche vengono integrati all’interno di un database relazionale MS Access pensato ai fini della loro consultazione anche da parte di utenti non esperti GIS. Tale database consente collegamenti e interazioni sia con un personal geodatabase ESRI che con il database spatial PostgreSQL (estensione PostGIS) all’interno dei quali sono stati archiviati i dati spaziali dedicati invece ad una utenza GIS specialist. Si prosegue con la descrizione delle tipologie di dataset territoriali in essi inseriti ai fini della loro archiviazione e del loro aggiornamento. - Il sesto capitolo risulta, infine, dedicato al testing e sviluppo (localhost) di un applicativo Webgis UMN Mapserver con front-end dinamico P.Mapper contenente una selezione dei dati spaziali di cui sopra. In relazione ad esso si delineeranno le caratteristiche fondanti, le categorie e le query di interrogazione, i parametri degli strati informativi di cui si intende consentire la visualizzazione. Il tutto consapevoli che la pubblicazione web di un Sistema Informativo Territoriale trova, di fatto, il suo fine ultimo non solo nel mero passaggio da un’utenza locale a una multiutenza condivisa del dato/database spaziale, ma anche nella sua auto-identificazione a strumento atto a supportate, favorire e attivare processi di condivisione informativa e partecipazione decisionale collettiva secondo dinamiche che, alternativamente, vertano ad un andamento di tipo top - down e bottom – up. Il lavoro, dopo le note conclusive, si chiude con le consuete indicazioni bibliografiche e sitografiche e tre allegati all’interno dei quali si riportano: due tabelle sinottiche relative allo screening sui parchi nazionali e regionali presentato nel corso del terzo capitolo, l’estratto di alcuni strati informativi inseriti nel file .map di Mapserver e infine un elenco delle sigle e degli acronimi incontrati nel corso dello scritto.

Résumé :

This project was aimed at critically analyzing the use of web geographical information system (GIS) applications in local government, and problems associated with the design, development, and implementation of web mapping applications in the case study of the municipality of Gävle, Sweden. The project included a scientific and thorough analysis of options for developing web GIS applications by using ESRI GIS software technologies. During this research project, the ESRI GIS software tools and packages were used to perform a comprehensive system analysis of the proposed web mapping application, to gain a better understanding of the available methods of map document and web GIS application performance optimization, and finally to develop a web mapping application prototype for the web map of the municipality of Gävle. The research results include the guidelines for preparing map documents to be published, optimizing ESRI ArcGIS Server web mapping applications performance, and some possible ways of customizing user tools and a user interface by using the Microsoft Visual Studio framework. This study proves that ESRI web-based GIS products provide viable tools for web mapping application design, development, and customization. The developed ArcGIS Server based web mapping application can be optionally improved and then be used instead of existing ESRI ArcIMS-based application in the municipality of Gävle.

Résumé :

Products are displayed in a shelf to market and sell to the public. It creates an interest and attracts people towards it. Likewise, any country or city can showcase itself by using Web over the internet which will attract the tourists from around the world. This example can be used for the city of Hyderabad. Hyderabad has truly become an international city and there are many multinational companies establishing themselves. It is rapidly becoming a hot spot for tourists from around the world because of its exotic locations and facilities provided by the government. The city has been famous for historical monuments and culture, but in the recent years it has developed into a world class IT destination for many multinational IT companies and due to this it has attained world recognition on the global scenario. The time is to reap the benefits of this image and promote the city’s tourist sector by globally marketing the tourist attractions, facilities and services in an innovative and better way so that tourists from around the world visit the city and thereby contribute to the country’s economy with the foreign currency.

This research deals with developing a Web-based GIS application that can promote the city’s tourist activities and also provide the users with an innovative way to access the spatial content of the city. GIS content forms the core component of this application as it provides the users with the spatial information about the place that is very close to reality. It supports the human tendency of “What you see is what you believe” by displaying the spatial information on the map. The application has been developed with the latest mapping server technology provided by Environmental Science Research Institute’s ArcIMS 9.1. This server software provides simple and easy methods to launch a Web-based GIS application over the Internet.

Texte intégral

Résumé :

The fluctuations in the demand for construction work have often resulted in skills shortages. This has led to the need for effective construction labour market planning strategies, which enable the construction industry to meet its skills requirements, particularly in periods of peak demand. Existing approaches to construction labour market planning have several limitations. They do not shed light on the socio-economic and spatially influenced issues within which the industry's skills shortages are rooted. There is, therefore, a need for more appropriate decision-support mechanisms that can take account of spatial problems in terms of skills demand and supply influences. Through industry involvement, this research has explored how GIS can enhance the labour market planning process in construction. The research briefly reviews the nature of labour market planning in construction, introduces geographic information systems, and highlights the opportunities they offer for overcoming the limitations of existing approaches. The implementation of the GIS-based system and its application to a specific labour market planning initiative is then presented. The evaluation of the system by prospective end-users reveals the enablers, barriers and benefits of the system implementation. Organisational issues that had a bearing on the implementation are also examined and recommendations made for further research.

Résumé :

Search and Rescue (SAR) operations aim at finding missing objects with minimum time in a determined area. There are fundamentally two problems in these operations. The first problem is assessing highly reliable probability distribution maps, and the second is determining the search pattern that sweeps the area from the air as fast as possible. In this study, geographic information systems (GIS) and multi criteria decision analysis (MCDA) are integrated and a new model is developed based upon Search Theory in order to find the position of the missing object as quickly as possible with optimum resource allocation. Developed model is coded as a search planning tool for the use of search and rescue planners. Inputs of the model are last known position of the missing object and related clues about its probable position. In the developed model, firstly related layers are arranged according to their priorities based on subjective expert opinion. Then a multi criteria decision method is selected and each data layer is multiplied by a weight corresponding to search expert&rsquo
s rank. Then a probability map is established according to the result of MCDA methods. In the second phase, the most suitable search patterns used in literature are applied based on established probability map. The developed model is a new approach to shortening the time in SAR operations and finding the suitable search pattern for the data of different crashes.

This research aims to investigate different solutions when creating the mostsuitable tool-set for implementation of outdoor attractions Web GISapplication using Web 2.0 technologies. The project has been set incooperation with a local Nedre Dalälven region Leader development teamfor their purposes and needs. Theoretical study has been taken in order todefine a software tool-set which would fit implementation process the best.The research approach includes collection of information about Web 2.0technologies, using available sources (databases which access was providedby University of Gävle), as well as discussion of differences between them.Analysed technologies were compared against applications' requirements.As the results of mentioned research, during development process three-tierarchitecture is going to be considered. The data tier and logical tier are goingto be located on the same server. For the mapping service Google Mapsserver is going to be employed. As an exchange format JSON is going to beused because it is much lighter then XML. On the client side JavaScriptwould suit well for the implementation because of Google Maps JavaScriptAPI and JSON exchange format that are going to be used. The PHP scriptinglanguage is going to implement business logic.The conclusion have been made that three-tier architecture suits thisapplication the best. The information about paths, which should be presentedon the map, is going to be stored in .gpx files rather than database, while filepath on the server side is going to be stored together with other details aboutit.This paper recommends the implementation of such an application and studyof further changes with a purpose of improving performance characteristics.

Résumé :

Satellite data potentially provide a useful tool for estimating forest cover and monitoring changes. Traditional forest surveying methods involve time consuming measurements of a large number of trees. Remotely sensed data may enable forest cover changes to be estimated very rapidly over large areas and with a minimum of ground data collection. At present the role of forest management in Britain is expanding, so that looking at forest cover changes is extremely useful for management purposes. The main task of this study was to detect plantation forest cover change information especially on thinned and clear cut areas. These changes were estimated using Normalised Difference Vegetation Index (NDVI) derived from SPOT HRV data, compared with Forestry Commission (FC) records and field investigations. To detect whether areas have been thinned and felled during the period of concern (1994-1997), three fundamental aspects were considered. First the pattern of forest cover was identified by using FC records and field investigations. This pattern was linked to SPOT data using NDVI. At this stage relationships between forest cover and structural variables (age, top tree height, mean diameter and basal area) were also examined. Second, changes over time were analysed by using NDVI measurements (1994-1997) and change detection methods, particularly to identify the pattern of felling. Third, pixel based forest cover changes in selected compartments were related and compared to FC thinning records and information collected by forest managers. A number of points about the ability of remote sensing techniques to provide an estimate of forest cover for management operations emerged from this study. First, it was found that NDVI changed spatially with different forest cover; spatial patterns were mainly identified in areas where major management operations (thinning and felling) were carried out. Second, temporal patterns of forest cover change, mainly due to felling operations were identified. Finally with a detailed analysis of thinned compartments, this study recognised changing patterns of forest cover, which were related to management operations. These findings should be very useful for operational planning in plantation forests. In particular, knowledge of spatial and temporal changes of forest cover may be useful in management operations where the availability of ancillary information is unreliable. These results appear to be sufficient for the initial stages of operational planning. However further investigations need to be undertaken to better understand a number of factors related to changes of forest cover.

Résumé :

Geographic Information System (GIS) is a technology that can help collect, edit, store, manage, transform, analyze and represent data. This research aimed to show how mobile GIS application can be designed, developed and applied to electric field work. An Android mobile application, which had been integrated with GIS was developed in Java. The prototype was tested and evaluated by employees of China Southern Power Grid (CSG). The resulting mobile application had three important features and functionalities: map view, location and electrical object querying, and attribute viewing and editing. According to the results of the user testing, the advantages of the application were its improved performance as brought about by the different scales used in the maps, its clear layout, and the speed of completing the query tasks. The disadvantages, on the other hand, were restrictions in the data types used and the query window. The study showed that with wireless communication, GPS and Location-based (LBS) supplements, electric utilities can benefit from this mobile GIS application in the following aspects: 1) eliminate the obstacles of going out in the field; 2) increase the flexibility of field work by faster access to data; 3) increase the accuracy and efficiency of field workers by dealing with the querying and editing task, and field mapping on a portable devices in real time. According to these aspects, electric field work can easily be enhanced by saving time, resources, and costs.

Résumé :

A Component Oriented Software Engineering (COSE) modeling environment is enhanced with the capability to import executable components and deliver applications through their composition. For this purpose, an interface layer that utilizes JAR libraries as components has been developed. Also, Domain Engineering process has been applied to Geographical Information Systems (GIS) domain and utilized towards converting the environment to a development framework. The interface layer imports JAR libraries into the COSECASE tool, which is a graphical tool supporting COSE approach and COSE Modeling Language (COSEML). As a result, systems can be designed using abstractions and then implemented by corresponding deployed components. Imported code is made available to the COSECASE environment through this interface layer. Also, Domain Analysis, Domain Design, and Domain Implementation phases of Domain Engineering process have been applied to the GIS domain. Components developed in this Domain Implementation phase have been imported into COSECASE. A simple GIS application has been designed and generated through the interface layer of COSECASE for demonstration purposes.

Résumé :

State Climate Offices (SCO’s) in the United States are critical conduits for improving weather and climate data in local communities. Two states do not have a state-recognized SCO: Tennessee and Massachusetts. Efforts are underway at East Tennessee State University to develop the Tennessee Climate Office (TCO). Currently, climate services and products are severely lacking across Tennessee. This thesis provides an improved methodology for an existing TCO product and outlines the development of a new product using Python scripting. Daily storm reports within the monthly climate report are automated and a Weather Forecasts Hazard Index (WFHI) web application is developed. Both products utilize data from the National Oceanic and Atmospheric Administration (NOAA), with the automated daily storm reports providing substantial time savings and the WFHI providing a high resolution web application for emergency managers and others to interpret potentially hazardous forecasts for extreme temperatures, high winds, snowfall/ice accumulation, and tornado/hail events.

Résumé :

A pesquisa recente em geoinformação indica que há benefícios no uso de programação funcional aplicada ao desenvolvimento de aplicativos geográficos. No entanto, o desenvolvimento completo de um sistema de geoinformação em linguagem funcional não é factível. O acesso a banco de dados geográfico exige um grande conjunto de operações de entrada e saída, de difícil implementação em linguagens funcionais. Essa dissertação apresenta um aplicativo que integra uma linguagem funcional (Haskell) com banco de dados espacial (TerraLib). Esta integração permite o desenvolvimento, em uma linguagem funcional, de aplicativos geográficos que manipulem dados em um banco de dados espacial. Esse aplicativo foi usado no desenvolvimento de uma Álgebra de Mapas, que mostra os benefícios do uso desse paradigma em geoinformação. Nosso trabalho mostrou que existem muitas vantagens no uso de uma linguagem funcional, especialmente Haskell, no desenvolvimento de aplicativos geográficos mais expressivos e concisos. Combinando Haskell e TerraLib, nós permitimos o uso de programação funcional em problemas reais, e tornamos o Haskell uma ferramenta ainda mais amplamente usada no desenvolvimento de aplicativos geográficos.
Recently, researchers in GIScience argued about the benefits on using functional programming for geospatial application development and prototyping of novel ideas. However, developing an entire GIS in a functional language is not feasible. Support for spatial databases requires a large set of I/O operations, which are cumbersome to implement in functional languages. This thesis presents an application that interfaces a functional language with a spatial database. It enables developing GIS applications development in a functional language, while handling data in a spatial database. We used this application to develop a Map Algebra, which shows the benefits on using this paradigm in GIScience. Our work shows there are many gains in using a functional language, especially Haskell, to write concise and expressive GIS applications. Combining Haskell and TerraLib enables the use of functional programming to reallife GIS problems, and is a contribution to make Haskell a more widely used tool for GIS application development.

Résumé :

As population increases, the need for public recreation facilities and resources increases. The U.S. Forest Service, National Park Service, and other recreation providers are constrained by limited time and funding to plan for, and implement, recreational facilities for the areas that they serve. Poorly located and designed recreational trails increase maintenance costs, resource degradation, and the inefficient utilization of public resources. The potential application of Geographic Information Systems (GIS) technology to this specific type of problem is examined through the comparison of hypothetical trail routes generated by several different methods, existing trail field surveys, office design, GIS user-assisted design, and cost-path analysis design. Each method is compared statistically and qualitatively by GIS methods and office based methods. Each hypothetical trail is ranked according to effectiveness of design, providing insight into trail design methods. The office designed hypothetical trails were consistently ranked highest by an expert forest road designer.

Résumé :

The primary aim of this study is to provide a cogent description and explanation of change in rural settlement between circa 1 ,500BC and AD 1845 for an area centred on Mynydd Cam Ingli, Pembrokeshire. Using a range of data sources, it evaluates the capability and validity of applying new methods and techniques offered by geographical information systems (GIS) to realise this aim and explore its potential for extending the agenda of possible archaeological and historical enquiry. Recently published work demonstrates a growing awareness of the potential benefits of applying GIS to archaeological resource management and landscape archaeology, yet there is little evidence of its application to an integrated archaeological, palaeoenvironmental, historical and geographical enquiry. It is not the intention to use archaeological and historical data to demonstrate merely the merits of GIS, but to judge its success in 'doing' archaeological and historical research. Data sources are used irrespective of their suitability for input and analysis within the GIS. Each source is examined individually to gauge their reliability and also to reveal what they tell us about past settlement. The extent and nature of the archaeological record is assessed using air photography together with associated palaeoenvironmental evidence. Opportunity is taken to reflect on the potential value of photogrammetry and GIS to cultural resource management. Historical maps and documents, in the form of census returns, estate plans, rent rolls, court rolls provide a crucial human element to the study. Yet it is the tithe map of 1845 that is at the hub of much of the analysis. Mid-nineteenth century agricultural production, land use and tenure are analysed in relation to topographic and other geographical constraints. The tithe map also serves as an 'anchor' for a retrospective study of settlement development. Archaeological, palynological and documentary evidence point to the ebb and flow of mixed agriculture and settlement on Mynydd Cam Ingli during the Bronze Age and Iron Age. Though there is palynological evidence of Dark Age activity, archaeological remains of settlement are not evident. Charters detail the parcelling out of land as burgages during the thirteenth century by Anglo-Norman lords and the establishment of an open field. Use of the upland for communal grazing was tightly controlled by the lordship, but rapid encroachment by squatters during the early nineteenth century reduced the area of commons dramatically. Remnants of open field survive on estate plans of the mideighteenth century and embedded within the tenurial pattern of the tithe map. It is suggested that agriCUltural productivity as indicated by the tithe rent-charge is not only constrained by environmental conditions but by the prolonged use of medieval farming practises that echo those of the former open field. The study suggests that the input of archaeological, historical and environmental data into a GIS increases the scale and range of possible enquiries and enables questions to be asked that would have been inconceivable using manual methods. However, success or failure of the application of GIS to this type of study depends on the willingness of the researcher not to forsake the traditional methods and techniques appropriate to the analysis of a diverse range of sources. Though methodologically eclectic, adopting a broad landscape approach in combination with the analytical power of GIS offers a formidable overarching methodology for studying the past. Although the study concludes by suggesting that the application of GIS is not itself unproblematic, it is argued that the work presented does illustrate its potential value.

Texte intégral

Résumé :

Effects of functioning transportation infrastructure are receiving more and more environmental and social concern nowadays. Nevertheless, preliminary corridor plans are usually developed on the basis of technical and economic criteria exclusively. By the time of environmental impact assessment (EIA), which succeeds, relocation is practically impossible and only preventative measures can be applied.

This paper proposes a GIS-based method of delimiting motorway corridor and integrating social, environmental and economic factors into the early stages of planning. Multiple criteria decision making (MCDM) techniques are used to assess all possible alternatives. GIS-held weighted shortest path algorithm enables to locate the corridor. The evaluation criteria are exemplary. They include nature conservation, buildings, forests and agricultural resources, and soils. Resulting evaluation surface is divided into a grid of cells, which are assigned suitability scores derived from all evaluation criteria. Subsequently, a set of adjacent cells connecting two pre-specified points is traced by the least-cost path algorithm. The best alternative has a lowest total value of suitability scores.

As a result, the proposed motorway corridor is routed from origin to destination. It is afterwards compared with an alternative derived by traditional planning procedures. Concluding remarks are that the location criteria need to be adjusted to meet construction

requirements as well as analysis process to be automated. Nevertheless, the geographic information system and the embedded shortest path algorithm proved to be well suited for preliminary corridor location analysis. Future research directions are sketched.

Résumé :

GIS can be used in tourism as a decision supporting tool for sustainable tourism planning, impact assessment, visitor flow management, and tourism site selection. Therefore, the potential for GIS applications in tourism is significant. The purpose of the study was fixed to explore the potential of using GIS for planning resources pertinent to ecotourism development. The study investigated a case study in Sundarbans which is the largest mangrove forest region of the world, located in the southern part of Bangladesh and the Indian region of west Bengal. However, the current study considered only the Bangladesh part of Sundarbans for study and prepared ecotourism planning for this region. The Sundarbans plays an important role for the national economy of Bangladesh because of its natural resources and tourism activities. Moreover, this forest has been facing some problems due to unplanned development and tourism activities. The ultimate result of unplanned development is land use change, increasing deforestation, biodiversity losses and decreasing upstream flows. Therefore, the study considered this mangrove for ecotourism planning and development and GIS used as decision supporting tools. Moreover, this study tried to find some answers from the research questions. Tourism is a phenomenon, which often highlights that lack of planning and management in terms of environmental concern. For ecotourism planning this thesis quantifies land use change in the Sundarbans over 33 years (1977-2010) using Landsat TM, ETM & MSS satellite imagery and prepared vector maps based on LGED map for ecotourism mapping in Sundarbans, GIS assist in this process. The study found that, the land use of Sundarbans changed over the study period and the density of forest declined at the same time. However, the change occurred because of various human activities and climate change effects. Tourism has a little bit of contribution in the periphery area for this change but tourism has not yet been considered responsible for these effects largely as it is at a very early stage. This research proposed for community development and involvement for local people as a part of hospitality services in ecotourism industries in this region because they can assist tourists according to their experience as guides in the forest. Moreover, they can be employed in the service industries operating or accompanying jungle boat trips and wilderness trails and assisting in transport operation. For ecosystem protection in Sundarbans this study proposed a 300 meters buffer zone around the sanctuaries. Finally, this study proposed an outline for ecotourism planning in the Bangladesh part of Sundarbans where GIS assist in the planning process.

Résumé :

This doctoral thesis introduces a novel methodology to optimize the use of forest biomass for energy purposes at regional scale, by means of GIS applications and economic tools. The procedure calculates, at first, the energy potential of a given forested area, as well as a reasonable location and dimension of a district heating power plant, based on local energy availability and energy demand. In a second step, it runs a cost-benefit analysis (CBA) to assess the economic feasibility of the plant. The CBA considers financial costs and benefit, social benefits and environmental costs, estimated by means of market and non-market valuation techniques. Financial, social and environmental flows are combined to produce four different scenarios, for which the net present value is calculated. Afterwards, a probabilistic sensitivity analysis is carried out, to assess the stability of the results when different assumptions of input values are included. Such procedure have been tested in an Italian case study, the valleys of Gesso and Vermenagna in the Piedmont region. These alpine valleys are interesting, because forests are at present under-utilized. At the same time, the presence of the Alpi Maritime Natural Park provides constraints to the use of natural resources; for these reasons, a carefull planning of the activities is fundamental to assure sustainability. The GIS methodology has been developed in GRASS GIS and automatized in python, while econometric computations were carried out in R. This procedure may facilitate energy planning and increase the efficiency of the forest-timber-energy chain.

Résumé :

Throughout history, military officers have relied on maps to provide spatial information and make informed battlefield and other problem-solving decisions. Today’s officers can put even more spatial information at a soldier’s fingertips if they are made aware of the power of geographic information systems and software. This paper makes the argument that an informal education and introduction to the uses of geographic information systems (GIS) during their participation in reserve officer training corps (ROTC) can help provide future officers with a basic understanding on how GIS can impact their ability to solve military relevant problems with these technologies and can aid in their decision making. This project created a web application using python and based on military mapping manuals and defense tools that allow a user to create a model of how quickly the user could be able to move over a given terrain. This web application was given to military officers in ROTC training at the University of Arizona prior to participation in a land navigation exercise to help them plan and prepare their path through the event. Students using the app prior to the exercise were able to see how the information provided by GIS can help them make decisions and times were compared between those that used the tool and those that did not. This tool, and the subsequent exercise provided increased awareness in military applications of GIS for those future military officers and helps inspire them to pursue more information on the technology.

Résumé :

The purpose of this study is to assist planners and scientists in assessing the economic implications of the USAID-funded Integrated Pest Management-Collaborative Research Support Program (IPM CRSP) research activities. The study presents a framework and a set of procedures for documenting, evaluating and communicating aggregate economic impacts of IPM technologies within targeted areas and across agro-ecological regions.

Performing an economic impact assessment involves consideration of many factors, from the adoption patterns of IPM technologies to the level of benefits and costs producers and consumers can reap from their adoption. Adopting the framework and procedures outlined in this study will help ensure that economic benefits of IPM CRSP activities are consistently and comprehensively evaluated and documented. The assessment process involves identifying and defining alternative pest management strategies, data and information collection, and analytical procedures.

Two case studies are carried out to demonstrate the functionality and practical nature of the framework. Partial budgeting and ex-ante economic surplus analysis are employed to estimate the aggregate benefits of IPM CRSP strategies in Bangladesh and Uganda. In Bangladesh, an altered schedule of hand weeding in cabbage production and Neem leaf powder as an insecticide for eggplants were selected for assessment. In Uganda, the maize variety Longe-1 and seed dressing with Endosulfan for management of bean fly and root rot on beans, are evaluated. Also, a Geographic Information System (GIS) is used to project the transferability of IPM CRSP strategies beyond the primary sites. Data on production, consumption, prices, price elasticities for demand and supply, and experiment costs are gathered and refined to derive aggregate benefits for each country. Expert questionnaires were developed to determine adoption rates, and to elicit information about yield and cost changes due to the adoption of these technologies. Agro-ecological and socio-economic data were collected to facilitate the spatial framework and examine adoption rate patterns. The GIS analysis gives insight into the spatial dimension of economic analysis and complements the effort of the IPM CRSP to globalize its activities.

The research findings show that the IPM practices investigated gave a substantial amount of benefits discounted over thirty years to both consumers and producers. This study has shown that IPM CRSP-induced pest management practices in Bangladesh and Uganda are viable and more profitable production practices than existing farmer practices. Efforts to promote the adoption of these technologies will likely result in more efficient production and greater economic rewards for the farmers, consumers, and in turn for the country as a whole. Finally, the study presents recommendations for further research relating to gender and cross-border trade issues to strengthen the functionality of the framework.

Résumé :

The subject of the report is to review and evaluate the potential for vector graphics in web maps. It ishoped that a web mapping only should display vector graphics. Compared to the traditional webmapping approach, that has raster tiles pre-rendered on the server side for each zoom level. Thedrawback with raster data is that it lacks in information content compared to vector data, which interms can contribute to a richer user interface. However, vector graphics, in comparison to raster datahave a complex data structure and are inefficient to handle such as raster data traditionally is managed.Thanks to new rendering techniques for vector graphics, such as by VML, SVG, but mainly throughthe canvas element, web maps can be improved since vector graphics can be drawn directly in theclient through the browser without the need to generate data on the server side and sent it to the client.By selecting three vector-based mobile mapping libraries that use HTML5, in particular the canvaselement, each library is examined and evaluated based on their ability to use vector graphics, bothperformance-wise, by randomly generating vector data on a map comprising of the world, but alsoaccording to a number of usability criteria. Thereafter, a mobile travel habit implementation isdeveloped based on one of the libraries that meets the criteria the best. The travel habit application isdesigned to register the user’s geographical movements and subsequently display the user’s completedtrip in terms of vector data on a map. The application is developed with the ASP.NET technique thatconsists of HTML, JavaScript and C# languages. Results show that each library is superior / comparesfavourably to the others for at least one of the assessment criteria. Based on the performance test forthe rendering of vector data, the Tile5 library performed best with a rendering time corresponding toapproximately half the time it took for the second best library Leaflet. However, since Tile5 indicatesdeficiencies in the documentation, Leaflet fits the overall established assessment criteria best and isselected for the implemented of the mobile application for travel habits. For future development, Tile5has the potential to become a useful and effective tool for vector web mapping and to compete withthe traditional mapping platforms that renders raster data.
Motivet till rapporten är att granska och utvärdera möjligheterna för vektorgrafik i webbkartor,förhoppningen är att i en webbkarta endast visa vektorgrafik. Istället för på det traditionella sättet medraster data som genererats färdigt på server-sidan för varje zoom-nivå av kartan. Nackdelen medrasterdata är att den är fattig på information jämfört med vektordata, som i sin tur kan bidra till ettrikare användargränssnitt. Dock har vektorgrafik jämfört med rasterdata en komplex datastruktur ochär ineffektivt att hantera så som rasterdata traditionellt görs.Tack vare nya rittekniker för vektorgrafik, så som genom VML, SVG men främst via canvaselementet, kan webbkartor förbättras i och med att vektorgrafik kan ritas upp direkt genom browserutan att behöva generera data på server-sidan. Genom att välja ut tre vektor-baserade utvecklingsbibliotek som använder sig utav HTML5 och speciellt canvas elementet, så undersöks och utvärderasrespektive bibliotek utifrån deras möjlighet att använda vektorgrafik, både prestandamässigt, genomatt slumpmässigt generera vektor data på en karta omfattande av hela världen, men också utifrån ettantal användbarhetskriterier. Därefter utvecklas en test implementation, d.v.s. en applikation för resvanor,baserat på den utav biblioteken som uppfyller kriterierna bäst. Res-vane applikationen ärinriktad på att registrera användarens geografiska rörelser och kan sedan visa användarens genomfördaresa i form av vektordata på en karta. Applikationen är utvecklad med ASP.NET tekniken som bestårutav HTML, JavaScript och C# språken. Resultatet från den empiriska undersökningen visar attkartbiblioteken utmärker sig på förmånligt men på olika områden. Utifrån prestandatestet förrendering av vektordata, presterade Tile5 bibliotek bäst med en renderingstid motsvarande ungefärhäften av tiden det tog för det näst bästa biblioteket, Leaflet. Dock ledde bristande dokumentation förTile5 till att Leaflet, till det stora hela sett, passade bedömningskriterierna bäst och kom attimplementeras i den mobila test applikationen för resvanor. För framtida utvecklings, har Tile5potential att utvecklas till ett användbart och effektivt verktyg för vektorkartläggning och för attkonkurrera med traditionella webbkartor som renderar rasterdata.

Résumé :

Availability of organized data is required for accurate prediction of structural or functional deterioration in sewer and water pipes. Toward this end, GIS provides a means for viewing, understanding, interpreting, and visualizing complex geographically referenced information to reveal data relationships, patterns, and trends. The primary objective of this research is to develop a standard GIS data model and applications of the model. In the future, these can be used to develop protocols and methods for predicting the remaining life of water and wastewater assets. The source data for this study is the utility data and other publicly available data from resources such as USGS, SSURGO etc. Field mapping files are generated from the source files and the standard data model. These are then programmed to the common Extensible markup Language (XML) file developed as a base which is then converted to the data model where the final form of utility data is stored. The data taken from the utilities is cleansed and analyzed to match the standard data model which is then uploaded through the common XML and stored in the data warehouse as a geospatial database. The geospatial database is an aggregated water and wastewater infrastructure data consisting of the utility data in standard data model format. The data warehouse is developed for utilities to store their data at a centralized server, such as the San Diego Super Computer Center. Web applications demonstrate the publishing, querying and visualization of aggregated data in a map-based browser application. This aggregation of data of multiple utilities will help in providing timely access to asset management information and resources that will lead to more efficient programs. This tool also furnishes the public with a convenient tool to learn about municipal water and wastewater infrastructure systems. This document gives an overview of how this process can be achieved using the above mentioned tools and methodologies.

Résumé :

Negli ultimi decenni molte linee ferroviarie sono entrate in disuso a causa della crescente affermazione del trasporto automobilistico e aereo e a causa dell inadeguatezza alle attuali esigenze di trasporto delle linee e delle infrastrutture connesse. Oggi le linee ferroviarie dismesse costituiscono spesso la base di un ricco patrimonio naturale che in molti Paesi del mondo si sceglie di recuperare e trasformare in percorsi verdi: tale trasformazione massimizza i benefici per la comunità locale a fronte di un minimo investimento di risorse finanziarie. In Italia sono circa 8.000 i chilometri ferroviari dismessi e, dopo molti anni di studi, ricerche e convegni sulla tematica, si è potuto assistere alle prime realizzazioni concrete che fanno aumentare di giorno in giorno i chilometri di percorsi dedicati alla mobilità non motorizzata. Nonostante tali confortanti presupposti continua ad essere necessario implementare le ricerche in tal senso: mancano progetti e indicazioni operative specifiche per la creazione di un sistema integrato di greenways in grado di svolgere funzioni di valorizzazione e fruizione delle risorse storico-culturali e delle attività turistico-ricettive. Si può dunque pensare di ripristinare tali percorsi dismessi trasformandoli in greenways dove l esperienza del viaggio costituisce un insieme di turismo, cultura e sport. L obiettivo è quello di fornire spunti di riflessione in merito alla possibilità di recupero e trasformazione di percorsi ferroviari dismessi in greenways, dimostrando come sia possibile riutilizzare tali tracciati, salvaguardando la qualità del paesaggio e fornendo nuove opportunità di utilizzo del patrimonio storico-culturale. La ricerca è suddivisa in due parti: la prima è dedicata allo stato dell arte del fenomeno delle ferrovie abbandonate e relativa trasformazione in greenways; la seconda invece, una volta individuata l area di studio, è rivolta all applicazione di un metodo basato sull analisi multicriteri in ambiente GIS, attraverso il quale è possibile valutare inizialmente l idoneità del territorio ad accogliere un processo di recupero dei tracciati ferroviari dismessi in relazione alle risorse territoriali presenti, e successivamente valutare l idoneità alla riconversione dei tracciati ferroviari presenti nel territorio analizzato in base a proprie caratteristiche e condizioni al contorno. I primi risultati hanno indicato l opportunità di scegliere quale area di studio gli ambiti paesaggistici afferenti al siracusano, indicati dalle linee guida del Piano Territoriale Paesaggistico della Sicilia. Infatti è emerso che nella regione tali ambiti sono fra quelli maggiormente ricchi di risorse naturali, culturali, e artistiche. Successivamente l applicazione multicriteriale associata al GIS ha permesso di individuare lo scenario che può avvalersi maggiormente della riconversione delle ferrovie dismesse in greenways fra i tre scenari ipotizzati, A1-finalità rurale, A2- finalità turistico/culturale, A3- finalità ambientali. Lo scenario A2 ha assunto un peso maggiore; per tale scenario è stata verificata la idoneità al recupero di due linee dismesse della provincia (Siracusa/Vizzini, Noto/Pachino) e, conseguentemente, sono stati scelti i tratti ferroviari sui quali approntare progetti di recupero e riconversione. I risultati progettuali ottenuti possono essere di interesse per i diversi attori, pubblici o privati che vogliono in futuro intervenire per il recupero e la valorizzazione, non solo dei singoli tracciati, ma anche del territorio e del paesaggio. Gli elaborati progettuali possono essere assunti come riferimento dai quali partire per sviluppare progetti di dettaglio a livello di tratti ed elementi. Inoltre essi costituiscono un risultato applicativo delle fasi di analisi e valutazione, dimostrando la validità dell approccio teorico. Lo studio, pur riferendosi ad un ambito territoriale preciso, fornisce riferimenti metodologici di validità generale applicabili in altri contesti.

Abstract The highly economic development in Taiwan area causes city regions tremendous population crowing. Nevertheless, an awkward situation of a limited land and natural resources is accompanied with all kinds of problems of urbanization. The importance of Urban-planning has begun to be noticed by the government organization. Because of the development of society and the change of population structure, the criterion of spatial plan of a city and the concept of planning (project) will have many different models to map out. Therefore, this study has deliberated many major factors of the structure of urban development, such as population distribution, population growth, land use, the situation of urban traffic and the urban disaster-prevention. Taking Tsou-Tun town as an example, from the contents of available urban plan and comprehensive review at the present stage, I applied ESRI ArcView, a GIS software, to setup an assistant information on graphic interface. A computer-automatic system to offer a timely and accurate reference on decision-making for the administration in the full-face planning is expected. Users can indicate the different information from the colors on the digital map, and get more various messages from overlaid maps. Also, a disaster prevention circulation on an emergency situation can be planned in advance to get a clear disaster-prevention message for decision-makers.

Résumé :

Researchers are in broad agreement that energy-conserving actions produce economic as well as energy savings. Household energy rating systems (HERS) have been established in many countries to inform households of their house’s current energy performance and to help reduce their energy consumption and greenhouse gas emissions. In Canada, the national EnerGuide for Houses (EGH) program is delivered by many local delivery agents, including non-profit green community organizations. Waterloo Region Green Solutions is the local non-profit that offers the EGH residential energy evaluation service to local households. The purpose of this thesis is to explore the determinants of household’s participation in the residential energy efficiency program (REEP) in Waterloo Region, to explain the relationship between the explanatory variables and REEP participation, and to propose ways to improve this kind of program. A spatial (trend) analysis was conducted within a geographic information system (GIS) to determine the spatial patterns of the REEP participation in Waterloo Region from 1999 to 2006. The impact of sources of information on participation and relationships between participation rates and explanatory variables were identified. GIS proved successful in presenting a visual interpretation of spatial patterns of the REEP participation. In general, the participating households tend to be clustered in urban areas and scattered in rural areas. Different sources of information played significant roles in reaching participants in different years. Moreover, there was a relationship between each explanatory variable and the REEP participation rates. Statistical analysis was applied to obtain a quantitative assessment of relationships between hypothesized explanatory variables and participation in the REEP. The Poisson regression model was used to determine the relationship between hypothesized explanatory variables and REEP participation at the CDA level. The results show that all of the independent variables have a statistically significant positive relationship with REEP participation. These variables include level of education, average household income, employment rate, home ownership, population aged 65 and over, age of home, and number of eligible dwellings. The logistic regression model was used to assess the ability of the hypothesized explanatory variables to predict whether or not households would participate in a second follow-up evaluation after completing upgrades to their home. The results show all the explanatory variables have significant relationships with the dependent variable. The increased rating score, average household income, aged population, and age of home are positively related to the dependent variable. While the dwelling size and education has negative relationships with the dependent variable. In general, the contribution of this work provides a practical understanding of how the energy efficiency program operates, and insight into the type of variables that may be successful in bringing about changes in performance in the energy efficiency project in Waterloo Region. Secondly, with the completion of this research, future residential energy efficiency programs can use the information from this research and emulate or expand upon the efforts and lessons learned from the Residential Energy Efficiency Project in Waterloo Region case study.

Rational formula is profoundly used to estimate peak flow rate in urban area as well as the watersheds lack of rainfall- runoffrecords. On the otherhand,the parameters of rational formula are not well-defined and thus the resulted peak flow rates for different return periods are not unique. Because geographic information systems and image analysis technologies are able to produce more accurate digital spatial data which are important to determine associated parameters of rational formula,such as runoff coefficient,time of concentration,---- etc.,for runoff estimation.The research is thusto use GIS and image processing softwares ArcView and IMAGINE to obtain parametervalue for proposed watershed.By fitting in rational formula ,the designedpeak flow rate for different return year can be produced. Also,since ArcViewsoftware employs AVENUE program,the proposed method also contains a series ofgraphic user interfaces to automatically generate outcomes of rational formulacalculatoion for different retuen periods which will be quite helpful for individual user.
