First, DEM is not a file format. DEMs can be represented in numerous formats (shp, tiff, etc). The GDAL tools are very simplistic, but they'll get the basic job done. If you want an accurate representation of the DEM, I would recommend getting familiar with GRASS GIS. At a minimum, you'll learn how to correctly deal with different/conflicting datum/projections. I put together a tutorial on this some time ago that was geared towards Xastir users. Should still be somewhere on the GRASS site. -- 73, de Brad KB8UYR/6 <rez touchofmadness com> _______________________________________________ Xastir mailing list Xastir@xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
