ENLiDAR (light detection and ranging) is an optical remote sensing technique which acts as a sort of radar with light, painting the target area with lasers and recording the time it takes to reflect back to the instruments. In the case of aerial LiDAR, this distance information is combined with GPS (Global Positioning Satellite) data. The result is a precise set of three-dimensional coordinates for any given point on the ground. During a fly-over of a selected area, thousands of laser pulses are bounced off the ground and the buildings and trees on it. The resulting LiDAR data, with the filtering and processing, can then be used to create accurate surface maps. Lithuanian archaeologists often use LiDAR data in combination with other established methods and techniques (eg., aerial photographs, ortophotographs, historical maps, GIS, field evaluation) for field use, mapping, visualisation, interpretation, and protection. LiDAR data were applied not only to find and map potentially new archaeological objects (barrows, hill-forts, historic charcoal burning sites), but also in reconstructing wetland sites and their environment. Different visualisation techniques enabled to highlight some aspects of the relief. Although the available LiDAR resolution is generally low, it is still indispensable for solving archaeological and cultural heritage issues. [From the publication]
