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
