Taking part
LiDAR - Ground truthing exercise
WHAT IS LIDAR?
LiDAR stands for (Airborne) Light Detection And Ranging.
The LiDAR laser can measure the height of the ground surface and other features in large areas of the landscape with incredible accuracy, providing highly detailed and accurate models of the land surface.

The Neroche Scheme undertook a LiDAR survey of our project area in 2008. The results of this survey will be used for a variety of purposes including ‘ground truthing’. Ground truthing is a voluntary field-based exercise involving teams/groups/individuals checking for the presence of any apparent archaeological features identified as a result of the survey.
The LiDAR image shown here is of the hillfort at Orchard Hill. This hillfort was only discovered in 1986, and the area is woodland. Ordinary aerial photography cannot detect the features, but lidar, which is able to 'strip' off the woodland, clearly shows the ditch surrounding the hillfort.
We are currently looking for any volunteers who may be interested in assisting with a ground truthing exercise. If you are interested please contact Tanya James, Neroche Community History Officer on 07881 850660.
