Hello all I have learn today that ESRI publishes under Apache 2 license a database of Coordinate Reference System (CRS) definitions, in complement with EPSG database. The ESRI database contains entries for some CRS not yet in the EPSG database, together with entries for other planets than Earth.
https://github.com/Esri/projection-engine-db-doc/ The same entries are available in various formats; the most convenient format for us may the the CSV tables, which we could translate to SQL statements for the database. Martin
