What is PostGIS?

PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS "Simple Features Specification for SQL" and has been certified as compliant with the "Types and Functions" profile.

PostGIS development was started by Refractions Research as a project in open source spatial database technology. PostGIS is released under the GNU General Public License. PostGIS continues to be developed by a group of contributors led by a Project Steering Committee and new features continue to be added.


Case Studies

Learn how PostGIS is being used around the world.

UC Davis Soil Resource Laboratory

The US Davis Soil Resource Laboratory publishes soil inventory data for the southwest United States using PostGIS and Mapserver. Six months ago they were using shape files for spatial data storage. With PostGIS, their data is integrated in the database and new avenues of display and analysis have been opened for them.

North Dakota State Water Commission

The North Dakota State Water Commission manages all their hydrological and spatial data inside PostgreSQL and PostGIS. Five years ago, they were using only proprietary software, now they are using mostly open source.

GlobeXplorer

GlobeXplorer serves terrabytes of imagery to clients around the world using PostGIS as their production database server. In 2004, GlobeXplorer migrated from Informix to PostGIS, and now they are serving over a million requests a day with PostGIS.
