Do you want to know Ground Sample Distance (GSD) or Altitude?

    The Ground Sample Distance is a measure of resolution in aerial photogrammetry. It is the distance between pixel centers as measured on the ground.

    This will determine the Altitude (Above Ground Level (AGL)) required to achieve a specific Ground Sample Distance given a known focal length and pixel size.
