Description: A Digital Terrain Model (DTM) is a 'bare earth' elevation model, unmodified from its original data source (such as lidar, ifsar, or an autocorrelated photogrammetric surface) which is free of vegetation, buildings, and other 'non ground' objects. The DTM is derived from LiDAR point clouds (QL1) and has a 1 ft resolution.For more information, contact: GIS Manager Information Technology & Innovation (ITI) Montgomery County Planning Department, MNCPPC T: 301-650-5620
