GCDIST

The GCDIST function computes great circle distance
           between two points on the earth.

USAGE:    ...GCDIST(RLAT1,RLON1,RLAT2,RLON2)

   Input argument list:
      RLAT1    - REAL LATITUDE OF POINT 1 IN DEGREES
      RLON1    - REAL LONGITUDE OF POINT 1 IN DEGREES
      RLAT2    - REAL LATITUDE OF POINT 2 IN DEGREES
      RLON2    - REAL LONGITUDE OF POINT 2 IN DEGREES
 
   Output argument list:
      GCDIST   - REAL GREAT CIRCLE DISTANCE IN METERS
