#107: CF Data Model 1.7 -----------------------------+---------------------------------------------- Reporter: markh | Owner: [email protected] Type: task | Status: new Priority: medium | Milestone: Component: cf-conventions | Version: Resolution: | Keywords: -----------------------------+---------------------------------------------- Comment (by markh): Replying to [comment:31 biard]: > Mark, > > I may have missed a lot as I have followed this stream.

The place where I thought it might be relevant is linked to the description of the [http://cf-pcmdi.llnl.gov/documents/cf- conventions/1.6/ch05s06.html grid_mapping attribute's aim]: `that the true latitude and longitude coordinates be supplied`. This requirement can be delivered in some situations by a pair of derived coordinates linked to the coordinate variables of the data. This isn't so helpful for NetCDF files but could be useful in the more general description. I think it would be plausible to remove all mention of grid_mapping from a derived coordinate description; perhaps it would be clearer, my explanation of this case seems a little contrived to me now. thank you mark -- Ticket URL: <https://cf-pcmdi.llnl.gov/trac/ticket/107#comment:32> CF Metadata <http://cf-pcmdi.llnl.gov/> CF Metadata This message came from the CF Trac system.
