gvSIG-Desktop 1.12. User manual
Oracle has its own system for cataloguing coordinate and reference systems. Miguel Ángel Manso, on behalf of the Polytechnic University of Madrid, has provided a list of equivalent values for the Oracle system and the EPSG system and this is included in the driver as a DBF file.
Conversions from one coordinate system to another are carried out by gvSIG since its performance has proved to be superior.
