The OGP’s EPSG Geodetic Parameter Dataset is a collection of definitions of coordinate reference systems and coordinate transformations which may be global, regional, national or local in application.
The primary EPSG Dataset is maintained in the online registry
, from which data may be accessed through a graphic user interface or through a service interface. The online registry contains the most current data. The Registry GML schema files are available here
Approximately twice a year snapshots of this data are also made available through files downloadable from here. The downloadable Dataset is in the following formats: MS Access, MySQL, Oracle, PostgreSQL. Area polygons are downloadable as a Shapefile. To download these files them you need to log in (requires having previously registered) and then go to the Download Dataset
The EPSG Geodetic Parameter Dataset is maintained by the Geodesy Subcommittee of the OGP Geomatics Committee. For more information about the Geomatics Committee please visit http://info.ogp.org.uk/geomatics
