This is a Raster data set. It contains the following raster data types:
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest 2.0
Ordinates (y-coordinates) are specified to the nearest 2.0
Planar coordinates are specified in Meters
The horizontal datum used is NAD83.
The ellipsoid used is GRS80.
The semi-major axis of the ellipsoid used is 6378137.00 meters.
The flattening of the ellipsoid used is 1/0.003352811.
