Airborne LiDAR is now the most widely used method of rapid and accurate terrain mapping. LiDAR systems are capable of capturing the height of both the terrain and objects on the terrain such as buildings, in amazing high-resolution detail.
LiDAR, which stands for Light Detection and Ranging (sometimes referred to as LaDAR or Laser Detection and Ranging), is an airborne laser scanning technology that uses a laser light emitter and sensors to measure the distance between the aircraft and the ground, including objects such as buildings and vegetation. When combined with the aircraft's global positioning system data highly accurate and high-resolution height data points can be measured on the ground.
LiDAR is ideal when very high accuracy height measurements are required for large areas and is very cost effective. Off-the-shelf LiDAR data, up to 10cm accuracy, is available for many areas across the UK including most major urban areas as well as rural and flood plain areas.
Bluesky's team of experts can give you help and advice on your LiDAR requirements, and will organise a dedicated LiDAR survey for you if the data you require is not available off-the-shelf.
