About the EPSG Dataset

The IOGP’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. Registry users may query and view the data, generate printable reports and create Well-known Text (WKT) compliant with ISO 19162. The online registry supports anonymous (guest) access, but also permits the user to register for additional services, such as the export of the entire Dataset.
Approximately twice a year snapshots of this data are also made available through MS Access files downloadable from here.  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 section. The Registry GML schema files are also available there.

The EPSG Geodetic Parameter Dataset is maintained by the Geodesy Subcommittee of the IOGP Geomatics Committee. For more information about the Geomatics Committee please visit http://www.iogp.org/geomatics or contact the Geomatics Committee Manager at lks@iogp.org.
