it seems that I have a problem with DEMViEWER which nobody else had. I cant open any files with the extension .DEM or .dem. Not even GTOPO30 dems. The files are greyed out on my MAC. I could open DTED files.

What could be the reason? My system Intel, OS X 10.6.11

Thanks for any comment.

Very handy tool for creating nice color hillshades, countours, etc. The tools for finding high or low points are also useful. Having greater control over grayscale images would be a nice addition, particularly as a replacement for some of the hillshade tools from gdal.
