GGIS architecture and development


The current GGIS was built based on GeoNode, a free and open-source software for deploying Spatial Data Infrastructure (SDI). GeoNode support the sharing of map layers, documents, as well as the creation of map viewers. As GeoNode complies with OGC standards, it allows map layers to be exchanged with external servers. GeoNode itself integrates multiple free and open-source components like PostGIS (Database) GeoServer (Server), MapStore (Maps), etc.

In addition to geographic coordinates (XY dimension), well and monitoring data also have a depth/elevation (Z dimension) and a time component (T dimension) that cannot be visualized in GeoNode. Therefore, a dedicated section was developed for sharing well and monitoring data. Once in the database, well and monitoring data are automatically converted into map layers that become available in GeoNode.

Furthermore, the home page of the GeoNode application was customized to provide access to the well and monitoring database and to provide a direct access to the most popular map viewers.
