EPSG Geodetic Parameters The Surveying and Positioning Committee of the International Association of Oil and Gas Producers (OGP), through its Geodesy Subcommittee, maintains and publishes a dataset of parameters for coordinate reference system and coordinate transformation description. The EPSG Geodetic Parameter Dataset has been included as reference data in UKOOA and SEG positioning data exchange formats, the GeoTIFF interchange format for georeferenced raster imagery, the IHS Energy Iris21, PPDM and POSC Epicentre data models. The dataset is distributed in an MS Access relational database and SQL script files. This package includes the PostgreSQL and mySQL scripts for creating the EPSG database.
