The Mapping Tool allows users to view, analyze, and share high-quality spatial data. It has two main components: a client side with which users interact and a server side where data are stored and calculations take place.
On the server side, data are stored in a Postrgres/PostGIS database and are served using GeoServer. Geoserver is an open-source, Java-based software server that can be used to view and edit spatial data. It uses Open Geospatial Consortium standards, including Web Map Services, Web Feature Services, and Web Map Tile Services.
