DSM, DEM, and DTM are all different ways of visualizing three dimensional relief of the landscape. All begin with overlapping aerial photos which can be viewed in stereo as 3D images by our photogrammetrists. A regular grid of points, called spot heights, is superimposed on the images where elevations are measured and recorded. The spot […]
