LiDAR Data

LiDAR (Light Detection and Ranging) is a technique using lasers to measure the distance between a survey aircraft and the ground

LiDAR types available

Digital Terrain Model (DTM)

Height data captured with a high vertical accuracy of +/- 5 to 15cm, great for modelling tasks where accuracy is important and is available in a variety of resolutions (25cm to 2m depending on your area). DTM strips out the surface features for a ‘bare earth’ model.

Digital Surface Model (DSM)

This also includes ground surface including buildings and other ground features such as energy and utility infrastructure, roads, street furniture, railway tracks and vegetation.

Both data options are available to purchase as a zip pack and include:

  • Plain text (CSV) for use in any application that reads text files (e.g Revit)
  • ASCII file format for use in GIS applications
  • DWG files for use in CAD come in the following types:
  • 2D / 3D contours with height written on each contour line
  • Point cloud can be used to create your own surface in CAD


Available in 25cm, 50cm, 1m and 2m resolutions. The accuracy of the data is between +/-5cm to 15cm.
