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/PostgreSQL includes the following functionality:
|
|
* Simple Features as defined by the OpenGIS Consortium (OGC)
|
|
* Support for Well-Known Text and Well-Known Binary representations of GIS
|
|
objects
|
|
* Fast spatial indexing using GiST
|
|
* Geospatial analysis functions
|
|
* PostgreSQL JDBC extension objects corresponding to the geometries
|
|
* Support for OGC access functions as defined by the Simple Features
|
|
Specification
