Abstract:V tem delu smo razvili geoprostorski informacijski sistem za pregledovanje in urejanje geoprostorskih podatkov preko spletnega vmesnika, ki omogoča večuporabniško interakcijo v realnem času. Uporabniki lahko dostopajo do podatkov v formatu GeoJSON iz različnih spletnih virov (npr. OGC storitve). Poseben poudarek smo namenili sinhronizaciji podatkov z uporabo protokola WebSocket, pri čemer smo preverjali vpliv velikosti podatkov in števila uporabnikov na hitrost prenosa, pri čemer so povprečne zakasnitve v testnih scenarijih znašale od približno 100 ms pri enostavnih akcijah do okoli 300 ms pri večjem številu sočasno povezanih uporabnikov.

Title:A web-based geographic information system with support for real-time viewing and editing of geospatial data
Abstract:In this work, we developed a geographic information system for viewing and editing geospatial data through a web-based interface that enables real-time multi-user interaction. Users can access data in the GeoJSON format from various web-based sources (e.g., OGC services). Special emphasis was placed on data synchronization using the WebSocket protocol, where the impact of data size and the number of users on transmission performance was analyzed. The results showed that average latencies in the tested scenarios ranged from approximately 100 ms for simple actions to around 300 ms when a larger number of concurrent users were connected.
Keywords:Geographic Information System, Geospatial data, Real-time interaction, GeoJSON, OGC
