The climatic emergency that involves the globe has led targets of greenhouse gas reduction in the EU and all over the world. In this scenario, recent advances in renewable renewable energy sources (RESs) have focused interest on the diffusion of power supplies that are produced by photovoltaic and wind plants. The non-programmable nature of these energy sources has led recent studies to consider the power-to-gas (P2G) solution as an opportunity for employing the curtailed electric energy by converting it into hydrogen. The localizations of P2G plants depend on several factors regarding power production, distances, and population distributions. The necessity of integrating these factors led this work to study the development of a cost function that is hosted by a webbased GIS (geographic information system) platform, thus allowing for the storage, elaboration, and web fruition of an entire data set that is related to the possible new localizations of P2G plants. The structure is based on open-source technology and creates a solution that is easily employable by specialists. The developed platform is composed of different remotely connected blocks that are solely based on open-source technology and is focused the interest on the territory of Sicily (Italy). GIS software, a RDBMS database, a geospatial server (Geoserver ), a Python optimization module, and a WebGIS visualizer are integrated. This work represents a scientific contribution to the management of energy sources, with a particular focus on policies that are based on hydrogen technology. In fact, different data sets that contain several levels of information that are related to the management and the localization of P2G plants will be even further employed in the future.

The Institute of Marine Sciences (ISMAR) and the Institute of Polar Sciences (ISP) of the Italian National Research Council (CNR) have gathered a substantial amount of heterogeneous geodata through the years in the Adriatic Sea, with different methodologies and for multiple scopes regarding geological, oceanographic, biological, anthropogenic aspects, and their interactions. To overcome challenges in datasets heterogeneity and fragmentation, a Marine Spatial Data Infrastructure (MSDI) has been set up, with the aim to integrate and preserve geodata, foster their reuse (e.g. the generation of scenarios for geological past and future developments by the application of numerical models), and ensure a good degree of FAIRness (FAIR: Findable, Accessible, Interoperable, and Reusable). The MSDI consists of a Spatial Relational Database Management System (RDBMS) based on specific data models designed following in part the INSPIRE Directive data specifications, a WebGIS, a metadata catalogue, and a cloud system. This paper shows the potentialities of this MSDI and discusses the main implementation steps, the elements that make up the infrastructure, the level of FAIRness reached, the main elements promoting FAIRness, and the gaps to be covered. Compliance with the FAIR principles represents a fundamental step to developing interoperability with European and international marine data management infrastructures for handling and exchanging multidisciplinary data.

Tourism is one of the most important factors in economic growth in Vietnam. However, it requires the balance between economics, social-cultures, and ecology because of their big impacts. In this paper, we propose a platform with mobile and web-based applications that can support smart and sustainable tourism in Vietnam for both local governments and visitors. The mobile application allows visitors to access location-based services to explore the visiting area, such as finding nearby natural attractions, as well as information to minimize the negative effects of tourism on the environment and the local community. It also enables users to report negative impacts to local government. The web application allows local authorities to monitor the status and trends of the habitant, natural environment, tourism infrastructure and activities in the area. The system uses geographic information systems (GIS) and remote sensing techniques to collect, analye and visualize various indicators of sustainability. The platform is developed with open-source technologies such as NodeJS, PostgreSQL, and Flutter. The paper demonstrates the feasibility and usefulness of the proposed platform through case studies in Hoa Binh and BacKan, two provinces have many attractive natural sites.

Mediterranean regions have experienced significant soil degradation over the past decades. In this context, careful land observation using satellite data is crucial for understanding the long-term usage patterns of natural resources and facilitating their sustainable management to monitor and evaluate the potential degradation. Given the environmental and political interest on this problem, there is urgent need for a centralized repository and mechanism to share geospatial data, information and maps of land change. Geospatial data collecting is one of the most important task for many users because there are significant barriers in accessing and using data. This limit could be overcome by implementing a WebGIS through a combination of existing free and open source software for geographic information systems (FOSS4G). In this paper we preliminary discuss methods for collecting raster data in a geodatabase by processing open multi-temporal and multi-scale satellite data aimed at retrieving indicators for land degradation phenomenon (i.e. land cover/land use analysis, vegetation indices, trend analysis, etc.). Then we describe a methodology for designing a WebGIS framework in order to disseminate information through maps for territory monitoring. Basic WebGIS functions were extended with the help of POSTGIS database and OpenLayers libraries. Geoserver was customized to set up and enhance the website functions developing various advanced queries using PostgreSQL and innovative tools to carry out efficiently multi-layer overlay analysis. The end-product is a simple system that provides the opportunity not only to consult interactively but also download processed remote sensing data.

Artykuł przedstawia możliwości budowy dwu- i trójwymiarowego, przestrzennego modelu zbiornika wodnego z wykorzystaniem narzędzi typu GIS. Zaprezentowane podejście pozwala na integrację danych pochodzących z różnych źródeł do jednego, spójnego modelu, stanowiącego interaktywną mapę obiektową projektowanego zbiornika. Dzięki takim rozwiązaniom możliwy staje się wielodostęp do mapy, poprzez aplikację typu WebGIS. Utworzone modele danych pozwolą wykonać przekroje poprzeczne terenu, umożliwiając wielowymiarowe analizy dyskryminacyjne na podstawie zebranej bazy wiedzy, której składowymi będą dane geodezyjne, geologiczne, a także geofizyczne i geostatystyczne. Ze względu na znaczną ilość napływających danych oraz mnogość formatów, w których będą one dostarczane, niezwykle istotną częścią projektu jest wypracowanie odpowiednich mechanizmów ich składowania. Ponadto wszystkie dane powinny posiadać współrzędne w jednakowym, przyjętym układzie współrzędnych. Zabiegi te pozwolą na uzyskanie przejrzystości i jednoznaczności danych, a także wygenerowanie mechanizmów wyszukiwania i raportowania, które w znacznym stopniu ułatwią proces zarządzania tak przygotowanym zbiorem danych.

This article introduces the possibility of building two- and three-dimensional spatial models of a mine flotation tailings reservoir, using GIS tools. The presented approach allows for the integration of data from different sources into a single, coherent model, which is an interactive object map of the designed tank. These solutions provide multiple ways of accessing the map using a WebGIS application. The created data models permit the generation of cross sections, as well as the performance of multidimensional discrimination analyses based on a compilation of accumulated knowledge including geodetic, geological, geophysical, and geostatistical data. Because of the large amount of incoming data and the multitude of formats in which it is delivered, a very important part of the project is to develop appropriate mechanisms for data storage. In addition, all the data should employ an equivalent coordinate system. These procedures will result in transparent and unambiguous data, as well as search and report engines which will greatly facilitate the management of such a prepared data set.

The general access to electronic information available in Internet significantly increased the need for spatial data. Dynamic growth of tourism is a positive phenomenon, because it contributes to the development of many so far poor regions of the country. On the other hand, strong tourist pressure on the environment calls for intensified efforts to protect valuable natural areas. Interactive web-based maps provide excellent solution not only to present information about the environment in an attractive way but also to protect nature by targeting tourist traffic. In this paper, a simple way is presented how to provide spatial data about Kozienice forests. For this purpose, generally accessible Google Maps application and vector and multimedia data gathered by employees of the forest district office were used. In the whole project, only free software was used and that makes it available to all users of Internet. In addition, it shows that without the knowledge of advanced programming techniques a valuable information website may be created.

The EU member countries' information society is a society in which the creation, distribution, dissemination, use, integration, and manipulation of information is an important economic, political, and cultural activity. Its economic counterpart is the knowledge-based economy, whereby wealth is created through economic exploitation of knowledge. The 2007/2/EC Directive 14 March 2007, adopted by the European Parliament and the European Council provides an opportunity to establish an Infrastructure for Spatial Information in the European Community (INSPIRE). The “Green Cracow” WebGIS portal is a result of a two-year interdisciplinary project “Vegetation map of the City of Cracow”. The geoinformation (GI) technology used in the project included: UMN MapServer, PHP MapScript, and the MySQL data base. Two services, WMS and WFS, involved in running of the “Green City” application corresponded with the Open Geospatial Consortium (OGC). Additionally, the following components were used to construct the whole WebGIS application: Apache ver. 2.2.9, PHP ver. 5.2.6, MapServer 5.2.0 CGI, MapScript (CSharp, Java, PHP, and Python), PHP/MapScript 5.2.0, Java Rosa 1.5.0, GD 2.0.35, FreeType 2.1.10, GDAL/OGR 1.5.2, and MySQL 5.0.67. The Internet client can access 8 different information layers: community type (54 classes; 15,993 polygons); valuation of natural qualities of the communities (5 classes; 14,773 polygons); protected plant stands (814 locations\points); city districts (18 polygons); local names (139 polygons), streets (6,592 lines); water (lines and polygons); and 1:10,000 and 1:5,000 map sheets (99 and 325 polygons, respectively). Raster layers including the cadastre map, aerial orthophotomap, and hillshade provided a backdrop to the vector geodata information and were used to power the visualisation of the UMN MapServer application. The data base with multimedia files contain 144 digital images of selected plant communities, 101 PDF files of map sets, and 97 KMZ files to be downloaded and directly integrated with the Google Earth application containing the QuickBird images for the Cracow area of May 2007. Installation of the “Green City” WebGIS application based on the Open source modules on the Cracow Municipality servers is a very important milestone achieved by the public administration units responsible for implementation of INSPIRE.
