The work is devoted to the development of spatial databases for the assessment of agricultural land. The geodatabase is aimed at geoinformation support of assessment, agroecological typing (groups, types of land) of agricultural lands, development of adaptive-landscape farming systems. The paper presents the structure of the database of regional and local levels. Three different ways of user interaction with the AgroGIS database are proposed. For practical implementation, it is proposed to use the object-functional approach to database development, based on the use of cloud data storage technology in the DBMS SQlite.
Background. Geoinformation support of agronomic geoinformation systems (AgroGIS) is aimed at assessing natural-territorial conditions and environmental factors in agrolandscapes, development of adaptive landscape farming systems. AgroGIS geodatabases serve to store, analyze and present spatial information on agricultural land. As shown by an analysis of literary sources, the term “geodatabase” was formed more than twenty years ago. At the same time different geodatabases are known: archaeological, cartographic, soil and others. They differ in the object of research, structure and content, as well as the way of data organization. This indicates the relevance of the topics of the present research.
Purpose. The purpose of the work is to develop the structure and content of the geodatabase agronomic GIS.
Materials and methods. The object-functional approach to database development, which is supported by object-oriented database management systems (DBMS) and classical relational DBMS, is used. The essence of this approach is to implement functional tasks taking into account the needs of the user.
Results. The main components of geodatabase in the form of separate sets of spatial classes (Climate, Relief, Soil, Vegetation, Hydrography, Agrolandscape) are proposed. At the same time the paper shows the need for practical implementation of agronomic geoinformation geodatabases from several aspects.
Conclusion. In the development of spatial databases of agronomic GIS the most important feature is the ability to constantly update information in the form of temporal component. Practical implementation of temporal geodatabases is possible with the use of non-relational database management systems, as well as methods of processing big data (Big Data).

The author focuses on the use of geographic information systems capabilities in the archaeological mapping, the results of the geoinformation analytical system creation “Crimean Archaeological sites”. The purpose of the work was to create a geodatabase for archaeological heritage sites in the Crimea, and also assess the degree of their legal protection in the current conditions of active land development and the formation of the Russian land legal system. On this purpose methods of digital mapping, processing the Earth remote sensing data and spatial analysis in GIS were used. For the first time, the mapping and specification of all the recorded coordinates for the Crimean archaeological sites was carried out, a geodatabase was created. This made it possible to identify “acute” situations associated with land use and creating a threat of destruction for archaeological sites. The results of the work were posted on the geoportal “Archaeological Monuments of the Crimea” to ensure continuous geodatabases updating and monitoring archaeological sites.

<p><strong>Abstract.</strong> Disasters such as floods, large fires, landslides, avalanches, or forest fires are often inevitable and cannot be fully prevented, but their impact can be minimized with sound disaster management strategies aided by the latest technological advancements. A key factor affecting these strategies is the time, because any delay can result in dramatic consequences and potentially human losses. Therefore, a quick geo-situation report of the disaster is highly demanded, but still not an easy task because – in most cases – a priori known spatial information like map data or geodatabases, are outdated, and anyway won’t provide an overview on the current situation. This paper provides an exploratory investigation to be smart in providing correct and timely geodata that can help in emergency cases; especially in support decision making in emergency and risk management. In particular, issues related to geodatabase design and visualization of a variety of geodata available play a key role when it comes to efficient data deployment and usability. To this end, a significant part of this research will be devoted to develop a concept for a geodatabase design and dataset management that helps assessing a disaster risk through a potential provision of data needed. Based on this consideration, the proposed concept is to create multi-disciplinary integrated geodatabases as well as an easy-to-use graphical user interface to access the obtained data. To address this concept, hard- and software solutions are being developed through the joint research project ANKommEn and its extension ANKommEn2. In those projects two automated unmanned systems, that is an aerial UAV (Unmanned Aerial Vehicle) and a ground based UGV (Unmanned Ground Vehicle), are being developed to provide up-to-date information of rescue scenarios. Within this paper, highlights about the two project parts will be briefly presented, and then the current state of the art in geospatial database management, followed by focusing on Postgres-based database management connected with QGIS, and finally current results like a Web Map Service will be discussed.</p>

En el marco de la práctica profesional de la maestría en Ordenamiento y Gestión del Territorio, se desarrolló la creación de una Geodatabase en la Dirección General de Catastro y Geografía (DGCG), la que sería el comienzo para una base de datos más segura y organizada, que permita una mejor distribución de datos geográficos generando para ello una cartografía confiable y altamente calificada. La creación de la Geodatabase permitió ordenar archivos de la elaboración digital de las hojas cartográficas, mapas departamentales, mapas municipales, mapa oficial del territorio de Honduras y otros que se generan desde el departamento de cartografía de la DGCG.Para la creación de la Geodatabase se utilizo una metodología la cual consistió en un proceso secuencial de pasos que incluyen: generación de File Geodatabases, Feature data set y Features Class, seguido de la migración de datos digitales en formato shapefile elaborados en el programa Arc View al programa Arc Map de ESRI, en donde se encontraron archivos desde Shapefiles, Tablas, Raster y otros compatibles a la estructura de datos nativa. Al mismo tiempo se realizó una comparación de la base de datos creada con la ya existente, con el fin de detectar posibles deficiencias o mejoras potenciales tanto de la geodatabase como de la manera de creación de los archivos digitales generados dentro de la DGCG.Se concluye que la creación de una geodatabase para la DGCG permitirá a corto, mediano y largo plazo un manejo adecuado de la información, mejor edición, actualización y administración de datos geográficos del departamento de Cartografía de la DGCG.Revista Ciencias Espaciales, Volumen 8, Número 1 Primavera, 2015; 509-519

Testo completoAbstract (sommario):
Topopographic mapping issues concern the area coverage at different scales and their age. The age of the map is determined by the system of updating. The United Nations (UNGGIM) have attempted to track the global map coverage at various scale ranges, which has greatly improved in recent decades. However the poor state of updating of base maps is still a global problem. In Saudi Arabia large scale mapping is carried out for all urban, suburban and rural areas by aerial surveys. Updating is carried out by remapping every 5 to 10 years. Due to the rapid urban development this is not satisfactory, but faster update methods are forseen by use of high resolution satellite imagery and the improvement of object oriented geodatabase structures, which will permit to utilize various survey technologies to update the photogrammetry established geodatabases. The longterm goal is to create an geodata infrastructure, which exists in Great Britain or Germany.

Extraction and dissemination of historical geospatial data from early maps are major goals of historical geographic information systems (HGISs) in the context of the spatial humanities. This paper illustrates the process of interpreting, georeferencing, organizing, and visualizing the content of a historical map of Cyprus in the context of GISs and highlights the development of a national-scale spatial database of the island in the 19th century. This method was applied to Lord Kitchener’s historical map of Cyprus (published in 1885), which is considered the product of the first scientific topographic survey of Cyprus, is rich in geographic information about the area, and covers the entire island at a scale of 1:63,360. Previous attempts to create historical geodatabases have either focused on small areas or, when conducted on a national scale, have been thematically focused. The positional accuracy of the map was found to be 1.08 mm in map units, which was equivalent to 68.76 m on the ground. Accordingly, the main categories of geographic content (land cover, administrative units, settlements, transportation/communication networks, stream networks/water bodies, points of interest, annotations) were digitized from the georeferenced historical map. The Web-based application developed in this study supported the visualization of the historical geographic content of the map and its comparison with modern basemaps. The creation of the geodatabase presented in the study provides a template for similar studies and a basis for further development of the historical geodatabase of Cyprus.

AbstractThe post-industrial landscape (PIL) is a generally accepted phenomenon of the present world. Its features are fossil in comparison to those ones in operating industrial landscapes. The required knowledge about the position, size, shape and type of PIL will help decision makers plan PIL future. The paper deals with the selection of identification features of PILs. Applicable data must be related to four landscape structures: natural, economic (land use), social (human) and spiritual. Present Czech geodatabases contain sufficient quantity and quality of data they can be interpreted as source of PIL identification criteria. GIS technology was applied for such data collection, geometric and format pre-processing, thematic reclassification and final processing. Using selected identification and classification criteria, 105 PILs were identified on the Territory of Czech Republic and classified into individual types. A SWOT analysis of results was carried out to identify the reliability level of data and the data processing. The identified PILs represent the primary results generally obtained in the Czech Republic. GIS approach allows repeated procedures elsewhere in EU member states because of some similarity of available geodatabases. Of course, an improvement of classification procedure depends on the real situation in each country.

This paper presents a workflow for the development of various Geodesign scenarios. The subject is important in the context of identifying patterns and designing solutions for a Smart City with optimized public transportation, efficient buildings, efficient utilities, recreational facilities a.s.o.. The workflow describes the procedures starting with acquiring data in the field, data processing, orthophoto generation, DTM generation, integration into a GIS platform and analyzing for a better support for Geodesign. Esri’s City Engine is used mostly for 3D modeling capabilities that enable the user to obtain 3D realistic models. The workflow uses as inputs information extracted from images acquired using UAVs technologies, namely eBee, existing 2D GIS geodatabases, and a set of CGA rules. The method that we used further, is called procedural modeling, and uses rules in order to extrude buildings, the street network, parcel zoning and side details, based on the initial attributes from the geodatabase. The resulted products are various scenarios for redesigning, for analyzing new exploitation sites. Finally, these scenarios can be published as interactive web scenes for internal, groups or pubic consultation. In this way, problems like the impact of new constructions being build, re-arranging green spaces or changing routes for public transportation, etc. are revealed through impact and visibility analysis or shadowing analysis and are brought to the citizen’s attention. This leads to better decisions.

The author’s vision on geographic information and cartographic support for studying the territorial features of the problems of socio-economic adaptation and socio-cultural integration of migrants is presented. The programmatic basis of the research is the GIS platform Mapinfo Professional, ArcGIS and the automated complex for processing, storing and analyzing personal data Questionnaire. The article presents a proven, author’s conceptual scheme of geographic information-cartographic support for studying the adaptation and integration of migrants of different categories (using the example of the North Caucasus) consisting of three blocks: “software platforms”, “geodatabases” and “mapping of statistical and information data”. The constituent elements of the first block are the geoinformation support of the study. The second block includes various empirical data. The third block presents the cartographic and graphical support of the study. The presented and tested conceptual framework may be used in other similar studies. The study provides a “step-by-step” description of the functional capabilities and advantages of building electronic geodatabases (“Foreign migrants in Russia”, “The attitude of the indigenous population towards migrants”, “Internally displaced persons”, etc.) in the “Application” program module, and also justifies the possibility of transferring and further cartographic visualization of tabular data in the used GIS platforms (Mapinfo Professional, ArcGIS). The article describes the printed sources used for the development of cartographic foundations through their digitization. The use of multiscale cartographic frameworks for visualizing quantitative and qualitative data at various historical periods made it possible to construct author cartographic schemes and cartographic diagrams reflecting the spatiotemporal transformations of the ADT of the studied territory, migration policy, migration and adaptation-integration processes in the North Caucasus.

Abstract. The integration of geodata and building models is one of the current challenges in the AECOO (architecture, engineering, construction, owner, operation) domain. Data from Building Information Models (BIM) and Geographical Information Systems (GIS) can’t be simply mapped 1:1 to each other because of their different domains. One possible approach is to convert all data in a domain-independent format and link them together in a semantic database. To demonstrate, how this data integration can be done in a federated database architecture, we utilize concepts of the semantic web, ontologies and the Resource Description Framework (RDF). It turns out, however, that traditional object-relational approaches provide more efficient access methods on geometrical representations than triplestores. Therefore we developed a hybrid approach with files, geodatabases and triplestores. This work-in-progress-paper (extend abstract) demonstrates our intermediate research results by practical examples and identifies opportunities and limitations of the hybrid approach.

This article presents the application of augmented reality through the use of devices in the valorisation of the geological heritage of six known geosites of the Jurassic or Cretaceous age, located in the South-East (SE) of the province of Burgos (Castilla y León, Spain). Using augmented reality techniques, geomatic resources have been developed that allow real-time interaction with different thematic layers (e.g., cartography, digital terrain model, etc.). Using these techniques, this paper proposes a virtual route in Google Earth and a Field Trip Guide with a detailed description of each site and suggested activities for educational use and one free geoapp. These geosites comprise three zones with deposits of dinosaur ichnites and three other sectors with marine fossils (Jurassic limestones), fossil trees, or singular karstic landscapes. The globalization of geodatabases allows the intelligent use of geo-resources and their use for tourism, didactic and scientific purposes.

AbstractThis research describes a quantitative, rapid, and low-cost methodology for debris flow susceptibility evaluation at the basin scale using open-access data and geodatabases. The proposed approach can aid decision makers in land management and territorial planning, by first screening for areas with a higher debris flow susceptibility. Five environmental predisposing factors, namely, bedrock lithology, fracture network, quaternary deposits, slope inclination, and hydrographic network, were selected as independent parameters and their mutual interactions were described and quantified using the Rock Engineering System (RES) methodology. For each parameter, specific indexes were proposed, aiming to provide a final synthetic and representative index of debris flow susceptibility at the basin scale. The methodology was tested in four basins located in the Upper Susa Valley (NW Italian Alps) where debris flow events are the predominant natural hazard. The proposed matrix can represent a useful standardized tool, universally applicable, since it is independent of type and characteristic of the basin.

Climate change has increased the occurrence and magnitude of debris flow events, especially in mountain areas. Moreover, their unpredictability requires to develop reliable methodologies for the evaluation of debris flow susceptibility, which is the starting point for risk assessment and management. In this paper, a modified version of the Debris flow Propensity Index (DfPI) is developed for the debris flow susceptibility estimation at basin scale. Bedrock lithology, fracture network, quaternary deposits, slope angle, channel network, and land use were identified as debris flow predisposing factors and were indexed by using open-access data and geodatabases. The objective of the proposed study is to develop a simple and economic procedure for the susceptibility estimation, easily to implement in GIS-based software for further analyses, such as propagation simulations or hazard scenarios, useful for planning mitigation strategies. The Can? Valley, a small valley located in the more famous Camonica Valley, (Lombardia Region, Northern Italy), was used as a case study for developing and testing the proposed approach.

La presente investigación estudia la aplicabilidad que tienen los Sistemas de Información Geográfica (SIG) en el proceso de análisis de la zonificación paisajística del cantón Portoviejo en Ecuador. La metodología consideró la caracterización del medio físico a través de la interpretación de unidades geomorfológicas y el medio biótico a través de la interpretación de uso y cobertura de la tierra. Con este análisis se obtiene información de partida sobre la geoestructura, ambiente morfogenético, paisaje, subpaisaje geomorfología, ambiente morfoclimático, geología, litología, pendiente, desnivel relativo, suelos y capacidad de uso de las tierras. Los resultados obtenidos en la fase de caracterización de los medios físico y biótico fue la creación de geodatabases y mapas en donde se identificó treinta y tres unidades de subpaisaje en el territorio de Portoviejo. Las conclusiones del presente trabajo investigativo demuestran que los análisis en un SIG dependen indiscutiblemente de la disponibilidad de información secundaria y de la información primaria generada, que contribuyó a una mayor precisión en la zonificación territorial, buscando una mejor y equilibrada utilización de recursos naturales o antrópicos en función de sus potencialidades y problemas.

This paper describes a WebGIS prototype developed for the Walloon administration to improve the communication and the management of sediments dredging actions carried out in rivers and lakes. In Wallonia, levelling dredged sediments on banks requires an official authorization from the administration. This request refers to geospatial datasets such as the official land use map, the cadastral map or the distance to potential pollution sources. Centralising geodatabases within a web interface facilitate the management of these authorizations for the managers and the central administration. The proposed system integrates various data from disparate sources. Some issues in map scale, spatial search quality and cartographic visualisation are discussed in this paper with the solutions provided. The prototype web application is currently discussed with some potential users in order to understand in which way this tool facilitate the communication, the management and the quality of the authorisation process. The structure of the paper states the why, what, who and how of this communication tool with a special focus on errors and uncertainties.

SUMMARYFast response and decision making about containment, management, eradication and prevention of diseases, are increasingly important aspects of the work of public health officers and medical providers. Diseases and the agents causing them are spatially and temporally distributed, and effective countermeasures rely on methods that can timely locate the foci of infection, predict the distribution of illnesses and their causes, and evaluate the likelihood of epidemics. These methods require the use of large datasets from ecology, microbiology, health and environmental geography. Geodatabases integrating data from multiple sets of information are managed within the frame of geographic information systems (GIS). Many GIS software packages can be used with minimal training to query, map, analyse and interpret the data. In combination with other statistical or modelling software, predictive and spatio-temporal modelling can be carried out. This paper reviews some of the concepts and tools used in epidemiology and parasitology. The purpose of this review is to provide public health officers with the critical tools to decide about spatial analysis resources and the architecture for the prevention and surveillance systems best suited to their situations.

The aggregation of population in big cities leads to the concentration of human activities, overconsumption of natural resources and urban growth without spatial planning and sustainable management. As a result, urban societies are exposed to various dangers and threats with economic, social, ecological, and environmental impacts on the urban surroundings. Problems associated with urban development are related to the existing geological conditions. Therefore, the provision of appropriate geological information about the urban environment is essential for every sustainable urban planning. The first systematic recording, codification and documentation of “Urban Geology” geothematic information in Greece was implemented by the Institute of Geology and Mineral Exploration (I.G.M.E.) in the framework of the project called “Collection, codification and documentation of geothematic information for urban and suburban areas in Greece - pilot applications”. Through the implementation of this project, geological mapping, geotechnical, geochemical, geophysical research and measurements took place at four pilot cities of Greece. Nafplio, the capital city of Argolis prefecture, was one of them. During the project, all compiled data were stored and processed in specially designed geodatabases in GIS environment in order to produce multifunctional geothematic maps and other digital products (DEMs, 2D - 3D surfaces).

Abstract Lobster farming produces higher organic carbon footprints; thus, a carrying capacity model must be developed specifically to address the issue. This study aimed to develop a carrying capacity for lobster farming based on a carbon deposition model. Bay and open waters (worst and best scenarios) carbon deposition models were developed using DEPOMOD. Two net cage configurations were used in each model. Current velocity, farming practices, and coastal geodatabases of seven provinces were analysed. The maximum carbon deposition in the bay was higher (1.67 kgC/m2/day) than in the coastal area (0.55 kgC/m2/day) for the single net cage configuration. Similarly, the bay’s four net cages produced a higher carbon deposition (4.11 C kg/m2/day) than the coastal net cages (0.88 kgC/m2/day). The bay has a smaller carbon footprint for both net cage configurations (68.98-140.12 m) compared to the coastal waters’ net cages (100.76-198.19 m). Based on the carbon deposition models, it is estimated that the assessed 598 Indonesia’s mariculture zones (total area of 1.47 million ha) could support 92,904 net cages (200 frames/net cage) capable of producing lobster of 557,429 tonnes/year. The proposed models could be used to replace the generic carrying capacity for lobster farming in Indonesia’s mariculture zones

This study aimed at (i) developing, evaluating and comparing the performance of support vector machines (SVM), boosted regression trees (BRT), random forest (RF) and logistic regression (LR) models in mapping gully erosion susceptibility, and (ii) determining the important gully erosion conditioning factors (GECFs) in a Kenyan semi-arid landscape. A total of 431 geo-referenced gully erosion points were gathered through a field survey and visual interpretation of high-resolution satellite imagery on Google Earth, while 24 raster-based GECFs were retrieved from the existing geodatabases for spatial modeling and prediction. The resultant models exhibited excellent performance, although the machine learners outperformed the benchmark LR technique. Specifically, the RF and BRT models returned the highest area under the receiver operating characteristic curve (AUC = 0.89 each) and overall accuracy (OA = 80.2%; 79.7%, respectively), followed by the SVM and LR models (AUC = 0.86; 0.85 & OA = 79.1%; 79.6%, respectively). In addition, the importance of the GECFs varied among the models. The best-performing RF model ranked the distance to a stream, drainage density and valley depth as the three most important GECFs in the region. The output gully erosion susceptibility maps can support the efficient allocation of resources for sustainable land management in the area.

Considering that the Philippines is archipelagic in nature and is exposed to disasters accentuated by climate change, water resource monitoring and management has been an important concern in the country. The design and implementation of an effective management scheme relies heavily on accurate, complete, and updated water resource inventories, usually in the form of maps and geodatabases. With the aim of developing a detailed and comprehensive database of all water resources in the Philippines, a 3-year project entitled “Development of the Philippine Hydrologic Dataset (PHD) for Watersheds from LiDAR Surveys”, has been initiated by the University of the Philippines Diliman (UPD) and the Department of Science and Technology (DOST). Various workflows has been developed to extract inland hydrologic features in the Philippines using accurate Light Detection and Ranging (LiDAR) Digital Terrain Models (DTMs) and LiDAR point cloud data obtained through other government-funded programs, supplemented with other remotely-sensed imageries and ancillary information. Since the project covers national-scale mapping and inventory, the implementation was structured to be a collaborative effort between fifteen (15) State Universities/Colleges (SUCs) and Higher Education Institutes (HEIs), along with multiple National Government Agencies (NGAs) and Local Government Units (LGUs). This paper presents the project’s general structure, focusing mainly on its attempts and accomplishments in strengthening individual capacities of all involved SUCs, HEIs, and stakeholders utilizing hydrologic data for different applications.

The Marina area represents an official new gateway of entry to Egypt and the development of infrastructure is proceeding rapidly in this region. The objective of this research is to obtain building data by means of automated extraction from Pléiades satellite images. This is due to the need for efficient mapping and updating of geodatabases for urban planning and touristic development. It compares the performance of random forest algorithm to other classifiers like maximum likelihood, support vector machines, and backpropagation neural networks over the well-organized buildings which appeared in the satellite images. Images were subsequently classified into two classes: buildings and non-buildings. In addition, basic morphological operations such as opening and closing were used to enhance the smoothness and connectedness of the classified imagery.The overall accuracy for random forest, maximum likelihood, support vector machines, and backpropagation were 97%, 95%, 93% and 92% respectively. It was found that random forest was the best option, followed by maximum likelihood, while the least effective was the backpropagation neural network. The completeness and correctness of the detected buildings were evaluated. Experiments confirmed that the four classification methods can effectively and accurately detect 100% of buildings from very high-resolution images. It is encouraged to use machine learning algorithms for object detection and extraction from very high-resolution images.

Abstract. Knowledge graphs (KG) are a virtual layer connecting disparate databases into an interoperable framework. Though the application of KGs for enterprises are increasing, geospatial KG design is not common. This presentation describes U.S. Geological Survey (USGS) research to build KGs for integrating geospatial and non-spatial attribute semantics of topographic data. Those geographic information system databases are composed of various feature types and metadata attributes organized various themes and stored in different data formats, such as geodatabases, flat-file spreadsheets, and raster images. The system being created tests two research objectives: 1) the feasibility of semantic technology approaches for geospatial data within the context of national topographic data and 2) the contribution to building a body of knowledge about system architecture for geospatial ontologies and linked open data. This presentation discusses the context of topographic data semantics, the problem and aims of building the system, and the integrated KG framework. The basic workflow and operations of the system architecture consisting of open-source software are described. The architecture modifies existing software with unique solutions such as performing GeoSPAQL queries with Postgres, a relational table datastore, and a map interface with extensions to support linked data queries as browseable graphs. As public spatial data infrastructure, the system is made available as a Docker Container on GitHub.

Innovative approaches that are based on the use of the European GNSS, Galileo and EGNOS, sensor technologies and LBS, are able to monitor, document and manage utility infrastructures’ data with an intuitive 3D augmented visualisation and navigation/positioning technology. A software and hardware-based system called LARA, currently under develop- ment through a H2020 co-funded project, aims at meeting that demand. The concept of LARA is to integrate the different innovative components of existing technologies in order to design and develop an integrated navigation/positioning and information system which coordinates GNSS, AR, 3D GIS and geodatabases on a mobile platform for monitoring, documenting and managing utility infrastruc- tures on-site. The LARA system will guide utility field workers to locate the working area by helping them see beneath the ground, rendering the complexity of the 3D models of the underground grid such as water, gas and electricity. The capacity and benefits of LARA are scheduled to be tested in two case studies located in Greece and the United Kingdom with various underground utilities. The paper aspires to present the first results from this initiative.

This multidisciplinary study is focused on the conservation and sustainable utilization of Lomelosia minoana (Dipsacaceae; subsp. minoana and subsp. asterusica) and Eryngium ternatum (Apiaceae), three local endemic plants of Crete (Greece) with economic interest. Using Geographical Information Systems and open-source geodatabases, detailed ecological profiles were compiled to illustrate the abiotic environmental conditions prevailing in their wild habitats. We examined for the first time temperature effects (10, 15, 20 and 25 °C) on seed germination and fertilization effects (INM, integrated nutrient management, and chemical fertilization compared to control) on growth parameters and nutrient content of leaves as well as their phenol content and antioxidant potential. L. minoana subsp. asterusica germinated better at 15 °C (61.25%), subsp. minoana at 10 and 15 °C (30% and 27.50%, respectively) while E. ternatum did not show significant differences. The seedling fertilization with INM resulted in 10–15-fold higher absorption of copper without toxicity compared with chemical fertilization and the control; INM was also superior to chemical fertilization in most of the macronutrients in leaves. The total phenol content and the antioxidant capacity of leaf extracts were positively affected by chemical fertilization in L. minoana subsp. minoana and E. ternatum. Both fertilization treatments almost equally affected the morphological and physiological characteristics of the examined taxa. In light of the above-mentioned and the research gaps bridged for the studied taxa, we re-evaluated and updated both the feasibility and the readiness timescale for their sustainable exploitation in economic sectors.

Abstract. Alongside a transition from steerable and centralized traditional electricity generation to intermittent and more decentralized renewable electricity generation from solar panels and wind turbines, Dutch energy transition scenarios project a widespread deployment of heat pumps and electric vehicles towards 2050. While clearly contributing to the decarbonization of the Dutch energy system, these developments impose challenges regarding electricity supply-demand mismatch and grid congestion. Spatially resolved electricity demand and supply profiles are required to gain a better insight into where and when such problems are likely to occur within the different scenarios. The present paper focuses on Dutch solar energy supply and features the construction of geodatabases of scenario-specific, spatially resolved electricity generation profiles for building, land and water-bound PV. Country-level PV capacities are geographically distributed based on spatial variance in roof PV potential and availability of suitable land and water use areas. Corresponding electricity generation profiles are constructed using historical meteorological measurements, a diffuse fraction model and a anisotropic transposition model. Empirically found performance ratio profiles are applied to account for a multitude of performance loss factors, including shading, dust and inverter efficiency. In 2050, building-bound capacity is projected to show only limited overlap with both land-bound and water-bound PV capacity. On the other hand, regions with considerable water-bound PV capacity also tend to show considerable land-bound PV capacity. Compared to the present-day situation, yearly country-level PV electricity generation is projected to be a factor 18.5, 15.7, or 7.7 higher in 2050 when respectively following the Regional, National or International Steering scenarios.

In the course of research to ensure the general requirements for geographic information support of the Unified automated control system of the Armed Forces of Ukraine (UACS of the Armed Forces of Ukraine), technical decisions on the establishment and operation of a technology for preparation and use of spatial data were substantiated. The foundation of the unified geoinformation environment of the Armed Forces should be service-oriented architecture (SOA) of distributed geodatabases. The purpose of deploying service-oriented architectures is to provide a single form of information resources management of the Armed Forces. Deploying a service-oriented architecture allows to create a single interface for internal users, who use both internal data stored in the internal (local) database and external data provided by other vendors. This model of data organization in terms of its architectural construction can be represented as an interconnected set of four levels models (the level of meta descriptions of services and authorizations of different categories users; the level of functional web services and access portals;the level of integration with legacy applications, databases and services, the level of technology reengineering and information system development). The geoinformation space of the UACS of the Armed Forces of Ukraine should be formed as an environment (network) of interconnected geoportals, the purpose of that is to consolidate information on available spatial data in the UACS of the Armed Forces of Ukraine environment. It’s determined that it’s optimal to use ESRI's ArcGIS server multi-user software with Enterprise performance level and Advanced functionality class as a software component.

Abstract. Through a (re)mapping and spatial modeling of a city’s past, exploratory web applications can be built to examine urban histories and dynamically engage scholars and the public. Working on Emory University’s OpenWorld Atlanta project (OWA), researchers used geospatial technologies and methods to extract data from archives and other sources to build historical data models, geodatabases, and geocoders that enabled the development of web-based dynamic map interfaces. With a focus on the early stages of urban development of the city of Atlanta in the southeastern United States, this platform provides exploratory visualizations of city history along with a wealth of detail for specific time periods, specifically circa 1878 and 1928, given the opportunity provides by key map publications of the city. These dynamically enabled historical maps were then connected to digital images, geospatial vector data, descriptive text, and labels and then structured in a content management system.While this project began as a digitization project centered on two atlases in the Rose Library collection at Emory University, it has grown to include contributors from several partner institutions. Therefore, this paper outlines the OWA project within a larger consortium of institutions and researchers focusing on production methods, platform development, interface design, and evaluation using open-data and open-source methods and software in cities' historical mapping and modeling. Drawing upon historical maps, city directories, archival collections, newspapers, and census data, projects like OWA allow researchers to analyze spatially grounded questions. In addition, they may serve the public as a valuable informational resource to learn about their neighborhood’s past and even contribute materials from family archives or stories.

Abstract The purpose of the article is to determine the optimal placement of the bomb shelter in the existing urban development. To achieve this goal, the authors used geoinformation systems. The authors set the task of processing topographic and geodetic data and related information. The authors implemented the task employing spatial analysis using existing ArcGis software modules. The use of the geoinformation system in the article makes it possible to significantly increase the speed of information processing than when using traditional methods. The use of the geoinformation system by the authors allows the creation of geodatabases with all the necessary attribute information. The authors researched the example of 522 micro-districts of the Saltivsky residential area of Kharkiv. The intellectual analysis of the existing information was carried out in this work using the geostatistical method for data transformation from a discrete to a continuous representation. In the article, the authors solved the task of determining the location of civil protection facilities using many factors and requirements. Visualization of the dangerous zones of the explosion of building debris during destruction, determination of the optimal route of movement of the population to the bomb shelter, and determination of the time required for this carried out. The obtained results, presented in the form of an algorithm, will make it possible to use the proposed sequence of actions to solve similar problems in the future. The authors developed an algorithm that significantly reduces the time for processing topographic and geodetic data and related information and solves the task of determining the location of civil protection facilities using many factors and requirements.

The sharp increase, circulation, accumulation by organizations of large enough volumes of spatial data used in geographic information systems to solve problems of updating and creating maps, require systematization and proper use, the task of systematization, processing and visualization of geodata for geographic information systems tactical level. Using the capabilities of GIS in the processing of geodatabases to obtain the necessary information, in turn, increases the efficiency of decision-making. This article is devoted to the development of requirements for the construction and operation of a geographic information system of the tactical level. The functional structure of the GIS of the tactical level of the Armed Forces of Ukraine is determined by the list of basic functions that this system implements. In addition, functionally, depending on the scope and content of GIS tasks is divided into two levels: operational and tactical, tactical. In turn, at each of the defined levels of the system, the common main functions implemented by GIS are: data entry and updating; data storage and retrieval; data analysis; output and presentation of data and results. Based on this GIS tactical level of the Armed Forces of Ukraine functionally consists of four subsystems: data collection, input and updating; data storage and retrieval; data analysis; output and presentation of data and results. At present, the topographic service of the tactical unit is not able to fully provide the lower level headquarters with electronic maps and prepare a detailed analysis of the necessary properties of the area. The use of information technology in the tactical chain of command of troops and weapons is possible only after improving the technical and organizational components of the topographic service of the connection. A significant step towards increasing the efficiency of geospatial data use and simplifying access to them is the implementation of portal solutions at the level of the Armed Forces of Ukraine.

Floods are the most frequent and destructive natural disasters causing damages to human lives and their properties every year around the world. Pakistan in general and the Peshawar Vale, in particular, is vulnerable to recurrent floods due to its unique physiography. Peshawar Vale is drained by River Kabul and its major tributaries namely, River Swat, River Jindi, River Kalpani, River Budhni and River Bara. Kabul River has a length of approximately 700 km, out of which 560 km is in Afghanistan and the rest falls in Pakistan. Looking at the physiography and prevailing flood characteristics, the development of a flood hazard model is required to provide feedback to decision-makers for the sustainability of the livelihoods of the inhabitants. Peshawar Vale is a flood-prone area, where recurrent flood events have caused damages to standing crops, agricultural land, sources of livelihood earnings and infrastructure. The objective of this study was to determine the effectiveness of the ANN algorithm in the determination of flood inundated areas. The ANN algorithm was implemented in C# for the prediction of inundated areas using nine flood causative factors, that is, drainage network, river discharge, rainfall, slope, flow accumulation, soil, surface geology, flood depth and land use. For the preparation of spatial geodatabases, thematic layers of the drainage network, river discharge, rainfall, slope, flow accumulation, soil, surface geology, flood depth and land use were generated in the GIS environment. A Neural Network of nine, six and one neurons for the first, second and output layers, respectively, were designed and subsequently developed. The output and the resultant product of the Neural Network approach include flood hazard mapping and zonation of the study area. Parallel to this, the performance of the model was evaluated using Root Mean Square Error (RMSE) and Correlation coefficient (R2). This study has further highlighted the applicability and capability of the ANN in flood hazard mapping and zonation. The analysis revealed that the proposed model is an effective and viable approach for flood hazard analysis and zonation.

The article considers the actual problem of the specifics of attracting additional resources when conducting military operations in modern conditions using the latest technologies and geo-information systems. The purpose of the article is to systematize modern technical means, namely geo-information systems for military purposes, which significantly affect the outcome of hostilities. An important task is the use of the latest technical and organizational developments. The authors consider in detail the advantages of using geographic information systems with up-to-date databases of attributive information and their use by both command and rank-and-file members of the Armed Forces. This will be facilitated by the spread of specialized applications that can be installed on an ordinary smartphone. In turn, the speed of making an informed decision will be influenced not by the availability of relevant information but also by the speed of decision-making. The solution to this problem will be facilitated by the developed interface of the latest software tools. The authors of this study solve the following tasks: they analyses the features of modern military operations and the conduct of hostilities with the help of modern technology and software tools. The authors systematize the features of attracting additional resources when conducting hostilities in modern conditions. The article proposes a general scheme for the use of human resources in modern warfare, as well as the collection, and processing of information, the formation of a database, and further use of data with the help of military GIS. The authors suggested using the interaction of satellite communications, modern methods of obtaining intelligence, and the interaction of headquarters and units directly performing combat tasks. As a promising direction for the development of the Armed Forces, it proposed to attach tasks to a digital information map and to accumulate and transfer information using modern geodatabases and data processing by modern battle management systems such as «ARTA» and «DELTA».

The paper has two main aims. Firstly, to postulate a physical geodatabase model of a geomorphological information system based on the already existing logical geodatabase model. Secondly, to define processes of geomorphological analysis based on the physical geodatabase model. The structure of the physical model follows the logical model and is divided into three parts: adopted layers (hydrology, geology, topography and others), basic layers (elementary forms, digital elevation model and derivatives, documentation materials, genetic groups of landforms, morphodynamic phenomena, basin based features and geomorphic network) and special layers (morphostructural analysis, comprehensive geomorphological analysis and so on). The geodatabase modelling methodology was used for developing the physical geodatabase model. The geomorphological analysis is based mainly on the layer of elementary forms (defined according to their morphology and morphometry) and the derived layer of morphogenetical forms (determined by genesis of landforms). The traditional methods of geomorphological mapping and also more recent concepts of geomorphological analysis were used. The concept is presented in the context of research in the surroundings of Prášilské jezero (lake) in the Šumava (Mts.). ESRI products were used to carry out the project.
