Note:  This header file was extracted from a digital orthophoto image
       that covers a full 7.5-minute quadrangle in Universal Transverse
       Mercator Coordinates.  The State Library converted that image to
       Montana State Plane Coordinates, units meters, and extracted
       portions of the image that cover a 3.75-minute quarter-quadrangle.
       The coordinates given in this file do not apply to the State Plane
       Coordinate images.
