GDSAWT

The GDSAWT routine decodes the grib grid description section
           and returns the earth's area covered by each grid point.
           The grid and earth coordinates are also returned. The
           edge points and corner points are given full weight now.

USAGE:    CALL GDSAWT(KGDS,KB,KA,XPTS,YPTS,RLAT,RLON,AWT)

   Input argument list:
      KGDS     - INTEGER (200) GDS PARAMETERS AS DECODED BY W3FI63
      KB       - INTEGER MAXIMUM NUMBER OF COORDINATES

   Output argument list:
      KA       - INTEGER NUMBER OF VALID POINTS COMPUTED
      XPTS     - REAL (KB) GRID X POINT COORDINATES
      YPTS     - REAL (KB) GRID Y POINT COORDINATES
      RLON     - REAL (KB) EARTH LONGITUDES IN DEGREES
      RLAT     - REAL (KB) EARTH LATITUDES IN DEGREES N
      AWT      - REAL (KB) AREA WEIGHTS IN M**2
