A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. [1][2] Much of this often happens within a spatial database; however, this is not essential to meet the definition of a GIS. [1] In a broader sense, one may consider such a system ...
The Open Geospatial Consortium has a spatial reference system standard based on the DERM called a [Discrete Global Grid] System (DGGS). According to OGC "a DGGS is a spatial reference system that uses a hierarchical tessellation of cells to partition and address the globe. DGGS are characterized by the properties of their cell structure, geo ...
OpenStreetMap (abbreviated OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration.Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and also import from other freely licensed geodata sources.

A transactional Web Feature Service (WFS-T) allows creation, deletion, and updating of features. A WFS describes discovery, query, or data transformation operations. The client generates the request and posts it to a web feature server using HTTP. The web feature server then executes the request. The WFS specification uses HTTP as the ...
