The TOPO enhancement was designed for images that had elevation values that range from about -12420 m to +8910 m. The range of values was chosen to break the display brightness range right at 148 (a value of 148 is "water" and 150 is "land" (using 128 image colors so that the values are grouped by twos)). >Anything inland >is just a mass of alternating black and white colors. This sounds strange to me. When I display the image, it looks correct especially if I use the image enhancement (or use EB to roll the enhancement table). >What enhancement should I use?.. I would start with the TOPO enhancement and modify it to maximize the contrast while keeping the breakpoint between water and land "correct" (correct means that Florida does not disappear or become huge). >or where did I go astray? I don't think you went astray anywhere (if you used the MAKEAREA positionals I sent you earlier). Does the image look weird if you use the IMAGE enhancement? Tom
