Morasko crater field: DTM 2

There is a digital terrain model for the Morasko crater field (western Poland) prepared using the Delanyay triangulation interpolation method. The input elevation data are represented by points nad breaklines. The points were collected from the digitization of contours from topographical map at 1: 10 000 scale. The breaklines represent special topographic features i.e. ridge lines, valley lines, and upper and lower edges of natural scarps. The breaklines were edited through some of the points as simple 2D polyline objects.
