Hello Randy
Is the image regular in location and resolution (with respect to a defined
coordinate reference system)?
If so, could an approach be to create a regular coordinate type which can
simply encode all of this information in one place?
such a type could be expanded at will to provide all the points and all the
resolutions required

Subject: [CF-metadata] how to capture horizontal spatial resolution of imagery
in a standard way
Although it works, using boundary variables to capture the horizontal spatial
resolution of imagery is inefficient.
Using cell methods with the keyword "interval" could be used to capture the
horizontal spatial resolution of imagery, but it implies the data values
represent specific points rather than areas. (I guess a "resolution" keyword
could be added for use with cell methods.)
Another option is to establish a standard_name for horizontal spatial
resolution and relate the value to the data variable using the
"ancillary_variables" keyword.
Does anyone have any thoughts on this ?
very respectfully,
randy
