Bryce, Most likely the problem is with coordinates. The units of the EXTENT are the map projection units (e.g. feet, meters, degrees, etc depending on your projection). Have a look at Pericles' tutorial at http://hypnos.cbs.umn.edu/tutorial/example1-6.html And don't forget to make sure that your input raster is "geo-referenced". And if your desired output projection is not the same as your input data projection, you will need to add a definition for each in the map file. Brent Fraser GeoAnalytic Inc. Calgary, Alberta
