Initial Release of PostGIS
Refractions Research is pleased to announce the inital release of PostGIS, a set of 3-D geographic object types for the PostgreSQL 7.1.x database server.
PostGIS includes the following functionality:
- Simple Features as defined by the OpenGIS Consortium (OGC)
- Polygon (with holes)
- The text representation of the simple features is the OGC Well-Known Text format.
- Geometries can be indexed using either R-Tree (not recommended) or GiST (recommended).
- Simple geospatial analysis functions.
- PostgreSQL JDBC extension objects corresponding to the geometries.
