PostGIS

PostGIS adds GIS spatial types and support to PostgreSQL. It is used by both Database and GIS Professionals who need to store and query both the spatial and non-spatial attributes of their data in the same queries.

PostGIS is a spatial database extension for the the PostgreSQL DBMS.  It provides new types to PostgreSQL geometry, geography, raster, and topogeometry and SQL/MM  OGC SFSQL compliant functions for doing GIS work such as cadastral management, back-end for Web mapping services.

 

It can also be used for network and road-routing using the complimentary pgRouting PostgreSQL extension.
