LiDAR data acquisition

swisstopo is planning another LiDAR survey of Switzerland and the Principality of Liechtenstein as the campaign launched in 2017 will come to an end in 2024. Airborne laser scanning is one of the most effective methods for measuring territory in 3D. It provides valuable, high-quality data in terms of both detail and accuracy. As the basis for digital terrain models, these data also contribute to other products and are used by many applications. 

Spiez Castle and the nearby harbour are shown in the form of a LiDAR point cloud. Each LiDAR point is coloured according to its classification and the intensity of the signal. Thus it is possilbe to distinguish between the ground, building roofs, building facades, vegetation and mobile objects such as boats.
