EA LiDAR Height Data

Summary

High accuracy mass capture dataset available in a range of resolutions and formats, including contours, suited to more detailed applications.  Samples below

Digital Surface Models (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. DSM's can be used to create 3D fly-throughs, support location-based systems and augmented simulated environments.

25cm, 50cm, 1m and 2m EA DSM (LiDAR)
The EA LiDAR data has an accuracy of +/-5cm to 15cm, with the spatial resolutions ranging from 25cm to 2 metres. The dataset has been developed to show the DSM (Digital Surface Model; where all surface objects are included). This data can be used in a range of GIS and CAD formats. The elevation data produced is suitable for a range of environmental applications, including flood risk assessment.

Digital Terrain Models (DTM)
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.

25cm, 50cm, 1m and 2m EA DTM (LiDAR)
The EA LiDAR data has an accuracy of +/-5cm to 15cm, with the spatial resolutions ranging from 25cm to 2 metres. The dataset has been developed to show a 'bare earth' Digital Terrain Models (DTM). This data can be used in a range of GIS and CAD formats. The elevation data produced is suitable for a range of environmental applications, including flood risk assessment.
