PostGIS adds support for geographic objects.......

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.

В· (Paul Ramsey)

System Requirements:

В· A complete configured and built PostgreSQL source code tree. PostGIS uses definitions from the PostgreSQL configure/build process to conform to the particular platform you are building on.
В· GNU C compiler (gcc). Some other ANSI C compilers can be used to compile PostGIS, but we find far fewer problems when compiling with gcc.
В· GNU Make (gmake or make). For many systems, GNU make is the default version of make. Check the version by invoking make -v. Other versions of make may not process the PostGIS Makefile properly.
В· (Recommended) Proj4 reprojection library. The Proj4 library is used to provide coordinate reprojection support within PostGIS.
В· (Recommended) GEOS geometry library. The GEOS library is used to provide geometry tests (Touches(), Contains(), Intersects()) and operations (Buffer(), GeomUnion(), Difference()) within PostGIS.
Program Release Status: Minor Update
Program Install Support: Install and Uninstall
