Paragraph 5.6 Coordinate Reference Systems, Grid
Mappings, and Projections, first sentence:
When the coordinate variables for a horizontal grid are not longitude and
latitude, it is required that the true latitude and longitude coordinates be
supplied via the coordinates attribute.
Are there any exceptions to this "rule" ?
The reason for asking is based on a scenario where the coordinate system and
constituent locations for the data points associated with the gridded data set
can be determined solely based on the grid mapping.
The reason for wanting to do this is to minimize the size of the netCDF file,
and the hardware resources required to process, store, and distribute the file.
