      PrecipMap

Purpose

---

      This is a program that demonstrates how to place an IDL map projection
      onto an image that is already in a map projection space. It uses a NOAA
      precipitation image that is in a polar stereographic map projection, and
      for which the latitudes and longitudes of its four corners are known.
      For additional details, see http://www.idlcoyote.com/map_tips/precipmap.html.
