PostGIS

Export to PostGIS.

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). PostGIS follows the OpenGIS Simple Features Specification for SQL and has been certified as compliant with the "Types and Functions" profile.

SIS Desktop 9 supports exporting of OGC simple features directly into PostgreSQL databases. SIS Desktop 9 can also create new columns and index columns directly in the database.

This is a cursor dataset and supports PostGIS 2.0.
