EPSG geodetic parameter dataset v6.10 release

Version 6.10 of the EPSG geodetic parameter dataset was released in April 2006 and may be downloaded without charge from www.epsg.org. This release contains a number of additions to data in the previous v6.9 (Feb 2006) release as well as the following:

Changes as documented in Change table records through 2006.29, but with actions still remaining on some earlier change requests.

Transformations included in the Guidance Note on Transformations for the Gulf of Mexico published by the Americas Petroleum Survey Group (APSG)

Data not previously available in EPSG database for Data for Alaska, Greenland, Faroe Islands, Finland, Mauritania, Mauritius and Malaysia

Typographic corrections to projection formulae for Oblique Stereographic, Lambert Azimuthal Equal Area, Albers Equal Area, Modified Azimuthal Equidistant, Krovak, and Cassini projection methods. Similar corrections have been made to Guidance Note 7 part 1 – Use of the EPSG Geodetic Parameter Dataset.

As for previous releases, the v6.10 dataset is available in two forms: either an MS Access database which also includes a data reporting capability, or as a series of SQL scripts for populating an alternative relational database application. There are several different SQL scripts for different SQL variants. In each format, the v6.10 release is accompanied by an updated version of the ReadMe file, in both PDF and MS Word formats.

If you have not seen this earlier, please note that the former European Petroleum Survey Group reformed last year as the Surveying and Positioning Committee of the International Association of Oil and Gas Producers (OGP). Similarly, the EPSG Geodesy Working Group has become the Geodesy Subcommittee of the OGP Surveying and Positioning Committee. This Geodesy Subcommittee continues with the same members as the previous EPSG Geodesy Working Group. This OGP Geodesy Subcommittee will continue to maintain the EPSG dataset. The dataset will continue to be known as the EPSG (geodetic parameter) dataset.

Best regards,

Jim Cain,
Member, Geodesy Subcommittee of the OGP Surveying and Positioning Committee
