supplementalInformation: In addition to giving the Bounding Coordinates in latitude and longitude, the limits of coverage for the gridded and projected data sets are also given in units of measure of the projection. This is usually the distance from a central meridian (the x-coordinate), or base latitude (the y-coordinate), in meters or kilometers of the given projection. For this data set those boundaries are:The Western-most boundary: -204 kilometersThe Eastern-most boundary: 188 kilometersThe Northern-most boundary: 5622 kilometersThe Southern-most boundary: 5040 kilometers
