Airborne Laser Scanning, also known as LIDAR (Light Detection and Ranging) enables highly accurate, remote capture of the terrain surface. Average accuracy is 15cm. In its many applications the system in addition to being cost effective also has the advantage of delivering good results for areas which are difficult to penetrate, such as forests and wooded areas. LIDAR is virtually the only cost effective method available for capturing elevation data from forest areas.
