#80: Add missing CF parameters to translate Coordinate Reference System properties to/from OGC Well-Known Text format -----------------------------+---------------------------------------------- Reporter: etourigny | Owner: [email protected] Type: enhancement | Status: new Priority: medium | Milestone: Component: cf-conventions | Version: Resolution: | Keywords: projections wkt -----------------------------+---------------------------------------------- Comment (by jonathan): Dear Etienne Thank for the final draft. Since no-one has commented further and three weeks have passed, this ticket should be accepted and included in the next version of the CF standard. At that time, Etienne should be added to the list of additional authors. Regarding your hesitation above, I would agree that it would be more logical to put it as a note to Table F1, where you have put some other remarks. I have therefore prepared a slightly modified version https://cf- pcmdi.llnl.gov/trac/attachment/ticket/80/issue80-2.txt of your attachment, with this small change made. Is that OK with you? We still need to consider what additions should be made to the conformance document. It seems to me that there are three, arising from these footnotes. * `reference_ellipsoid_name`, `prime_meridian_name`, `horizontal_datum_name` and `geographic_crs_name` must be all defined if any one is defined. * If `projected_crs_name` is defined then `geographic_crs_name` must be also. * If there is a CRS (Coordinate Reference System) definition, `semi_major_axis` must be defined, and either `inverse_flattening` or `semi_minor_axis` must be defined. We can't require `longitude_of_prime_meridian` in the last one, because there is a default. In this last point, what exactly does it mean to say there is a CRS definition? I mean, what formal criterion should the CF checker use to decide this?
