Overview

Our LiDAR data is sourced from the Environment Agency, and available as a Digital Terrain Model (DTM) or Digital Surface Model (DSM).

DSM’s measure the height values of the first surface on the ground. This includes terrain features, buildings, vegetation and power lines etc. DSM’s therefore provide a topographic model of the earth’s surface.

DTM’s provide a topographic model of the bare earth / underlying terrain of the earth’s surface. They are usually derived from DSM’s by digitally removing the cultural (man-made) and vegetation features.
