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
|
2013-12-23 21:59:44 +01:00
|
|
|
by a Project Steering Committee and new features continue to be added.
