Refractions Research is pleased to announce the release of PostGIS 0.8.0, the first version of PostGIS to support all the functions in the OpenGIS "Simple Features for SQL" specification. 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). Since we started the PostGIS project in 2001, we have had the goal of supporting all the functions in the SFSQL specification, so finally completing that goal is a big step! We have included the OpenGIS SFSQL test script in the distribution so you can test it out yourself. Among the (many) new SFSQL functions we have added are: - Contains(), Within(), Touches(), Disjoint(), - Overlaps(), Intersects(), Crosses(), Relate() - Intersection(), GeomUnion(), Buffer(), Difference() - ConvexHull(), SymmetricDifference() Also some non SFSQL functions, inspired by the spec: - Aggregates: GeomUnion() in-memory geometry aggregate - Aggregates: MemGeomUnion() memory-safe slower aggregate Version 0.8.0 also includes support for the recently released PostgreSQL version 7.4. PostGIS is open source software licensed under the GNU GPL. For more information, see http://postgis.refractions.net __ / | Paul Ramsey | Refractions Research | Email: pramsey@refractions.net \_
