[CF-metadata] how to capture horizontal spatial resolution of imagery in a standard way

Hi Randy,

Thanks for the explanation - that cleared things up a lot for me and I
certainly see what you're getting at now. I liked the "resolution"
proposal and could see us and many others using that too. I think this
requires no standard name and is just an addition to the cell methods
part of CF?

I don't know how much you want to flesh that out further; it would be
potentially useful to be able to express non-square pixels, different
units for resolution (angles, kilometers, etc) and perhaps even a means
to link to a sampling function.

However, I think it would be a useful addition even in the simplest
form, so I'd suggest avoiding getting hung up on too many details that
can be added later and just get something in.

Cheers,

Mike.
