Topographic and image maps of archaeological landscapes can be made using airborne LiDAR (Light Detection and Ranging) data. Such maps contain more three-dimensional data than conventional maps and may be more spatially accurate. In addition to providing a record of topography, LiDAR images may reveal surface indications of archaeological deposits unnoticed when using more conventional discovery techniques. LiDAR data and derived imagery need to be integrated with existing forms of archaeological data for their full potential to be realized.
