Paper Abstract

There are many applications for which there is a strong need to analyze digital terrain elevation data (DTED). However, the availability of DTED is limited. For some areas of the world, DTED is not available at all, and for other areas it may be only partially available. This introduces significant problems if analysis is required for areas of constrained DTED availability. On the other hand, compressed arc digitized raster graphics (CADRG) maps provide a guaranteed source of digital data that contains a limited amount of elevation information, namely elevations that occur along the contours in the maps. Unfortunately, CADRG maps typically contain a significant amount of additional visual information that obscures features of interest, making difficult the automated locations of contours and the subsequent transformation into DTED.
