3D maps created from aircraft mounted lasers are helping the National Trust uncover secrets at the historic Canons Ashby estate in Northamptonshire, UK. Working with specialist archaeological and heritage practice ArcHeritage, the National Trust commissioned aerial mapping company Bluesky to complete a LiDAR survey of an area of 690 hectares, around and including the estate. From the millions of individual laser measurements collected, Bluesky created high-resolution 3D models of the bare earth surface and of its surface features, including building and trees. Analysis of the Bluesky models has already uncovered evidence of more than 300 potential archaeological features within the survey area, whilst comparison with aerial photographs, dating back to the 1940s, is helping to identify more recent features and activities. www.bluesky-world.com
