Airborne LiDAR (Light Detection and Ranging) is a form of indirect data capture whereby a laser scanner mounted either within a aircraft or Unmanned Aerial Vehicle (UAV) is used to capture surface data over large areas. From targeted sub-centimetre surveys to larger landscape based surveys, this data can be used to accurately map minor topographical variations - cutting through thick vegetation to reveal a wealth of archaeological detail.
Airborne LiDAR data has revolutionised the way in which archaeologists understand and manage the historic environment
Typically capturing a 3D measurement every 10-200cm LiDAR can be used to reconstruct complex three dimensional data for the chosen area within a Geographic Information System (GIS).Such models can be used for analysis and interpretation, as LiDAR captures minute variations within the elevation of the ground surface even features with relatively little surface expression, invisible to the naked eye, can be easily identified.
We have extensive experience of applying LiDAR data within archaeological survey and assessment. Using such data our staff can rapidly assess large areas for archaeological potential, create detailed visualisation and setting models and derive detailed topographic information relating to sites.
