C SUBPROGRAM:  GDSAWT     GRID DESCRIPTION SECTION AREA WEIGHTS
C   PRGMMR: IREDELL       ORG: W/NMC23       DATE: 96-04-10
C
C ABSTRACT: THIS SUBPROGRAM DECODES THE GRIB GRID DESCRIPTION SECTION
C           AND RETURNS THE EARTH'S AREA COVERED BY EACH GRID POINT.
C           THE GRID AND EARTH COORDINATES ARE ALSO RETURNED.
C           EDGE POINTS AND CORNER POINTS ARE GIVEN FULL WEIGHT NOW.
