“…In general, the term WebGIS is accepted as a strategy for accessing and dealing with geographic information through the internet environment [17]. WebGIS is covered in detail in a number of publications, and it is a widely accepted term [18]. According to Dorman [19], WebGIS is "a software and hardware configuration that enables the sharing of maps, spatial data, and geographic operations using common web communication protocols such as HTTP and WebSockets".…”

With the rapid development of internet technologies in recent years, the shift from the desktop to the web platform can be seen within geospatial analysis. While analytical tools, such as buffer or clip, are routinely used in desktop environments, WebGIS deals with geographic information, including geospatial analysis, within the online environment. The main aim of this paper is to perform a comparison and evaluation of vector-oriented online geoprocessing tools in a WebGIS environment, supported by the development of a custom solution for geospatial analysis. The application called GeOnline is developed and tested as a case study to demonstrate the availability of spatial analysis tools within the web browser. It implements the specialized geospatial library Turf.js, which allows using non-trivial geospatial analysis, such as intersect, clip or calculate centroids. It handles client-side processes. Both a functionality comparison and performance testing are carried out, while the paper primarily focuses on data-driven (data-based) analysis and not only on visual-driven (visual-based) analysis. The comparative study evaluates five geospatial tools (ArcGIS Online, GISCloud, CARTO, FOURSQUARE, GeOnline) and summarizes the solutions from different aspects, including the number of supported operations. Finally, performance tests on GeOnline separately and among alternative solutions are performed. While ArcGIS Online is considered the most comprehensive solution on the market, GeOnline performs well compared to alternative solutions.

“…Another method for publishing map tiles is a folder directory with map tile files. This method does not require any server infrastructure [40] and web hosting is sufficient. Unlike the other pilot studies, the style was not stored in a JSON file, but defined directly in the web page's code under the "style" variable.…”

Recent developments in web map applications have widely affected how background maps are rendered. Raster tiles are currently considered as a regular solution, while the use of vector tiles is becoming more widespread. This article describes an experiment to test both raster and vector tile methods. The concept behind raster tiles is based on pre-generating an original dataset including a customized symbology and style. All tiles are generated according to a standardized scheme. This method has a few disadvantages: if any change in the dataset is required, the entire tile-generating process must be redone. Vector tiles manipulate vector objects. Only vector geometry is stored on the server, while symbology, rendering, and defining zoom levels run on the client-side. This method simplifies changing symbology or topology. Based on eight pilot studies, performance testing on loading time, data size, and the number of requests were performed. The observed results provide a comprehensive comparison according to specific interactions. More data, but only one or two tiles, were downloaded for vector tiles in zoom and move interactions, while 40 tiles were downloaded for raster tiles for the same interactions. Generally, the WebP format downloaded about three times fewer data than Portable Network Graphics (PNG).

“…Only a few countries around the world (China, Russia, North Korea, and Czech Republic) have a full‐featured local alternative of Google Maps. Mapy.cz is the Czech alternative to Google Maps, and Mapy.cz Panorama is the Czech alternative of Street View 12 . It was launched in 2013 and covers most of the Czech Republic, including lower class roads.…”

Currently, virtual reality (VR) is a trend both in general and in specific fields such as interactive maps. The article aims to test the possibilities of deployment of low-cost virtual reality environment for the 3D spatial panoramic application. It discusses and compares modern trends in hardware (panoramic cameras and glasses) and software in the field of virtual reality. Many panoramic map applications (e.g., the well-known "Google Street View") allow us to navigate through applications using VR headsets or on an ordinary 2D monitor. The main aim of the article is to design, develop, and deploy VR map application with different levels of user interaction. It presents two pilot studies with different user's interactivity and technical solutions: "simple" 2D-based map with 360 • panoramic photos and "true" 3D application for VR glasses. The article focuses on the possibilities of creating low-cost map applications. Therefore, the working process "from camera toward to virtual map application" is described as followed-up case studies.
