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.
