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)
    • Point
    • LineString
    • Polygon (with holes)
    • MultiPoint
    • MultiLineString
    • MultiPolygon
    • GeometryCollection
    • 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.

PostGIS is an open-source project released under the GNU General Public Licence.
