Using the EPSG geodetic parameter dataset (Guidance Note 7-1) This document gives detailed information about the Dataset contents and its maintenance. It includes annexes covering Data Naming Conventions and Rules for Deprecation. New updated version of the Guidance Note will be available soon. Coordinate Conversions and Transformations including Formulas (Guidance Note 7-2) This document provides the formulas for executing coordinate conversions and coordinate transformations using the coordinate operation methods supported in the EPSG dataset. Geodetic parameters in the Dataset are consistent with these formulas. EPSG Geodetic Parameter Registry – Developer Guide (Guidance Note 7-3) This document has no relevance to GeoRepository and it has been withdrawn. EPSG Geodetic Parameter Relational Database – Developers Guide (Guidance Note 7-4) This document is intended to assist computer application developers in using the EPSG geodetic parameter relational database and SQL scripts. It may also be useful to other users of the data. Readers are recommended to have read Part 1 of the guidance note before this part. New updated version of the Guidance Note will be available soon.
