Ticket Resolution Summary Owner Reporter
#34 fixed Add new grid mappings cf-conventions@… edavis
Description

1. Title

Add new grid mappings to the existing list.

2. Moderator

John Caron

3. Requirement

A number of grid mappings are being used that are not listed in CF. Make additions to the existing list.

This is a follow-up proposal to the proposal in CF Trac ticket #18.

4. Initial Statement of Technical Proposal

Add the following projections:

  • Lambert Cylindrical Equal Area (EPSG 9834 for spherical earth, EPSG 9835)
  • Mercator (EPSG 9804 for one standard parallel, EPSG 9805 for two standard parallels)
  • Orthographic (EPSG 9840)

5. Benefits

Allow existing data using non-CF defined grid mappings to be CF compliant.

6. Status Quo

Data that is otherwise CF compliant using grid mappings that are not supported by CF.

7. Detailed Proposal

CF Wiki page: GridMapNames - currently at version 11

#35 fixed delete "associated" in CF standard, chapter 5, introduction, paragraph 3 cf-conventions@… jonathan
Description

This was raised by John Caron, and Brian Eaton and Jonathan Gregory agree.

Change

We recommend that the name of a multidimensional coordinate variable should not match the name of any of its dimensions because that precludes supplying an associated coordinate variable for the dimension.

i.e. delete "associated", which has a technical meaning in the CF standard that is not meant here.

#36 fixed Correction proposed to subsection headings of Appendix D cf-conventions@… jonathan
Description

The various vertical coordinates described by Appendix D of the CF standard should be titled as unnumbered subsections, not as examples. They were unnumbered subsections in the beta CF standard document, and the formatting was changed when the document was translated to docbook. There was a similar problem with Appendix F, which was corrected by ticket 18.
