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
|
|
will be submitted for conformance testing at version 1.0.
|
|
|
|
PostGIS has been developed by Refractions Research Inc as a research project
|
|
in open source spatial database technology. PostGIS is released under the
|
|
GNU General Public License. We intend to continue development as time and
|
|
resources permit. Our list of future projects includes enhanced technology
|
|
for data loading and dumping, user interface tools for direct data access
|
|
and manipulation, and support for advanced topologies at the server side,
|
|
such as coverages, networks, and surfaces.
