Notes

---

      Note: Longitude and latitude are input in the NAD 27
      datum and output in the WGS 84 datum. This datum
      is only for the continental US (conus) an is an
      average. This routine shows how to do a 3
      parameter datum shift when delta x,y,z are known.
      Use this code as an example for datum shifting.
      Will need to know the datum ellipsoid and
      ellipsoid center shift values.
