Special Issue Information

Dear Colleagues,

The past decade has seen dynamic development of Web applications of Geographic Information Systems (Web GIS). In a relatively short time frame, Web GIS have evolved from simple websites focused primarily on data presentation and dissemination into interactive online applications serving a variety of purposes. From the architectural point of view, this evolution has been achieved by two different approaches to the classic three-tiered client-server composition. The first one expands the classic "thin client" logic into a Service Oriented Architecture (SOA) context, in which both Data Access and Business Logic tiers are located in the cloud, and the Web GIS client functionalities are constricted to initialising remote procedures and displaying their results. The other Web GIS construction philosophy involves "thick client" and hybrid approaches, which demand higher performance from the client machine in return for better responsiveness and increased interactivity. These advancements in Web GIS architectural designs have been stimulated by the availability of new hardware and software solutions. In particular, WebGL hardware acceleration allowed for the introduction of fully three-dimensional Web GIS client technology by means of the Open Source CesiumJS library, while DHTML tools for spatial data processing and analysis such as Javascript Topology Suite (JSTS) and Cesium Analytics SDK shift the Web GIS frontend paradigm even further towards a fully interactive thick-client contained entirely inside a web browser. This architectural flexibility has paved the way for a wide spectrum of Web GIS applications, ranging from data presentation websites, through Decision Support Systems (DSS) equipped with simulation capabilities, remote data processing and analysis systems, mobile mapping solutions, to Virtual Reality and Augmented Reality applications. This Special Issue intends to collect the latest research in the area of Web GIS architectures and applications. The topics for this Special Issue include but are not limited to the following:

- Novel applications of established Web GIS technologies;

- Mobile implementations of Web GIS;

- Web GIS architectures for multidimensional data processing and analysis;

- Web GIS for Big Data processing and analysis;

- Virtual Reality (VR) and Augmented Reality (AR) applications of Web GIS;

- Integration of Artificial Intelligence in Web GIS applications;

- Advancements in Web GIS for Geovisual Analytics.

Possibilities for Assessment and Geovisualization of Spatial and Temporal Water Quality Data Using a WebGIS Application

The provision of webGIS-based water quality data services has become a priority area for both the public and administrative sectors in the context of the pandemic emergency associated with the global spread of COVID-19. Current geographic, monitoring and decision supporting systems, typically based on web-based geospatial information, greatly facilitate the sharing of spatial and temporal data from environmental databases and real-time analyses. In the present study, different water quality indices are determined, compared and geovisualized, during which the changes in the quality of the shallow groundwater resources of a settlement are examined in the period (2011–2019) in an eastern Hungarian settlement. Another objective of the research is to determine three water quality indices (Water Quality Index, CCME Water Quality Index, Contamination degree) and categorize water samples based on the same input spatial and temporal data using self-developed freely available geovisualization tools. Groundwater quality was assessed by using different water quality indices. Significant pollution of the groundwater in the time period before the installation of a sewage network was shown. Regarding water quality, significant positive changes were shown based on all three water quality indices in the years after installing a sewage network (2015–2019). The presence of pollution apart from the positive changes suggests that the purification processes will last for a long time. Full article

In this paper we describe the potentialities of a tool for the visualization of experimental results directly on a three-dimensional model. The case study concerns the visualization of the results of a dynamic finite element analysis (FEA/FEM) applied to the calculation of seismic risk on works belonging to the Italian infrastructural heritage, specifically bridges, viaducts and overpasses. The project is based on finite element analysis performed on an exemplary set of eight structures located on the Italian territory, performed by means of the open-source software framework OpenSees, according to the guidelines indicated in the Technical Standards for Construction NTC08. The application created for this project is classifiable as a webGIS, since all data are georeferenced and visualized on a map through an application executed through a browser. The graphical interface displays the interested works on the map of the Italian territory and allows to select them by mouse click. Following the selection, a 3D rendering of the model of the work and the surrounding terrain is shown, in which the results of the analysis are represented using color gradients directly on the three-dimensional model. The necessary tools are present for the selection of the type of result and for the animation in real time of the response of the work to the seismic action. The 3D representation is freely navigable by the user due to intuitive tools of panning, rotation and zoom through mouse and keyboard. The application takes advantage of HTML5, CSS and Javascript to show graphical features such as Cartesian diagrams of accelerograms used in modal analysis. Full article
