West Jakarta is one of the cities in the DKI Jakarta province which has great tourism potential, especially on cultural and historical tourism. In the city, there are lots of historical heritage buildings during the Dutch colonial era. However, in fact the information about it is still limited especially for foreign tourists that know more about Bali as Indonesia. One of the methods to introduce the tourism is by using webGIS technology as it is the aim of this research that develop a tourism webGIS of West Jakarta which can be accessed by internet media. By using webGIS, it can be displayed West Jakarta tourisms that equipped with map location point and its travel route, and it can be accessed by internet browser without using GIS-processed software. The displayed tourisms are cultural and historical, culinary, shopping, family and religious tourisms. The webGIS was created by using Location Based Service (LBS) method that utilizes Google Maps API and Framework CodeIgniter. With LBS, the coordinates of tourist locations in the form of lattitude and longitude originating from the Google Maps application can easily be inputed in the webGIS code structure. This WebGIS was successfully accessed through an internet browser both on a computer and smartphone device, and also with usability test by distributing questionnaires to 40 respondents. The questionnaires contain several questions regarding the effectiveness, simplicity, and satisfaction during accessing the webGIS. Based on the results of the questionnaire, it can be concluded that the tourism webGIS application of West Jakarta classified into categories sufficiently effective, simple and satisfying.

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.

Geographic Information Systems (GIS) are now considered a valuable and essential tool to epidemiology. Spatial analysis through visualization, exploration and modelling allow for a deeper comprehension of the spatial and temporal dynamics of diseases and may be used to suggest and support epidemiologic hypotheses. The Internet is nowadays the preferred means for the electronic sharing of data and it still evolving. Its advent has also pushed for the development of powerful proprietary and Open Source (OS) technologies to provide a standard platform for the management, visualization and analysis of spatial epidemiologic data.

Geographic information systems or geographic information science is a combination of computer-mapping capabilities with additional database management/data analysis tools. GIS is widely used in various sectors such as environmental science, urban planning, agricultural applications etc. Public health is another focus area, where GIS has been used for research and practice areas such as epidemic surveillance and monitoring, among others. The journey of use of GIS in public health spans more than a century and GIS application in public health has evolved from the simple maps to the higher level geostatistical analysis and interactive WebGIS in recent times. GIS is an analytical tool which differs from conventional computer-assisted mapping and any statistical analysis programs in its ability to analyze complex data and visual presentation of spatial data. Specialized GIS techniques such as network analysis, location-allocation models, site selection, transportation models, and geostatistical analysis are well established and used in many developed and developing nations. Unfortunately owing to the high cost of licensed software and specialized skills for advanced data analysis, use of these techniques is limited mainly for the research and by few experts. GIS is proved to be useful for various public health practices and research purposes including epidemiological surveys/investigation, implementation research, program/policy decision making and dissemination of information. The advantage of using GIS is that maps provide an added dimension to data analysis, which helps in visualizing the complex patterns and relationships of public health issues, thus many unanswered questions in public health, can be understood well through use of GIS techniques. Use of GIS in public health is an application area still in its infancy. Wider use of GIS for public health practice such as program planning, implementation and monitoring in addition to building evidence base for the policy making will help reduce inequities in health and provide universal healthcare. Overall, GIS is a helpful and efficient tool especially for public health professionals working in low resource settings. In the future with inclusion of advanced GIS technology like WebGIS can help reach the goal of optimal health care services globally.

WebGIS technology has been constantly improved, with its functions increasingly powerful and rich, as Web technology develops rapidly. With such features as platform independence and service reliability, WebGIS is accessible in a wider range, and its functions and applications are continually expanded, where more diverse, complex and flexible applications can be made by interactions with Web information services. Thus, the requirements of the groundwater information management system can be met by the application of WebGIS technology in groundwater information management. Using Web technology and ArcGIS API for JavaScript script language to call the map service on ArcGIS Server server, it realized the display of map on the system platform, realized the basic GIS function of the system, and combined with database technology to complete the real-time query function of monitoring data. Two advanced spatial analysis functions of groundwater vulnerability assessment and groundwater level isoline analysis were realized by using the geographic processing service of ArcGIS Server. It provides users with visual and intuitive groundwater spatial data analysis, and also provides an effective method for the wide application of spatial analysis. As well as realized the location of groundwater monitoring station and the display of the latest groundwater data. Based on Internet technical standards and a distributed system structure, the system can display, store and analyze spatial information and attribute data, and takes advantage of the spatial information for analysis, simulation and evaluation to solve such complex problems as the assessment, warning and management of groundwater overexploitation areas, exploring a new way for the dynamic supervision, warning and management of local groundwater.

In the European ancient foundation city, the past forms a constitutive part of its structure. However, it is not easily recognizable in cities like Milan, where the ruins of monuments of imperial era (as the Theater, the Amphitheater and the Circus) have been submerged by the urban stratification. The recent success of visualization systems by web (such as GoogleMaps or Bing) have highlighted a widespread need for knowledge of places, which can be satisfied through an innovative application of tools as GIS. This chapter explains how, in the virtual space-time of a webGIS, it is possible to provide specific paths, that accompany any user, even if he doesn't have specific skills, to discover the immanent remote past of the city, described by an appropriate display of its cartographic and iconographic heritage.
