Contour lines, range rings, watershed analysis, view shed analysis, high and low point location can be calculated and marked on the surface of solid terrain models. An example is shown below.

Green Mountain, West of Denver, Colorado


Size: 11" x 12" x 1.68", scale: 1" - 400'. Shape is from Colorado GeoCache lidar data . The image is from USGS .6 meter data. Contour lines are on 10 meter intervals. Four circular range rings have a 200 meter spacing and are centered on the peak of Green Mountain. Calculated water drainage is marked as valley "stream bed" lines. Line width for all lines was 3 pixels. The image resolution is 500 pixels per inch.
