Nova Scotia Topographic Database - Digital Terrain Model (DTM)

Part of the Nova Scotia Topographic Database (NSTDB), DTM is a vector data set of spot elevations collected from aerial photography. An elevation point is collected at ground level approximately every eighty meters in an irregular grid pattern. These spot elevations, or mass points, can be used to create profiles of the ground or Digital Elevation Models (DEM).
