By laser scanning from aircraft or helicopters, also known as LiDAR (Light Detection and Ranging), you can determine the height of the landscape with great accuracy.
We operates two multi pulse laser scanners
The market demand for height models with high accuracy has resulted in COWI investing in the ALS LiDAR system from Leica.
The ALS has a heightrange of 200 m to 6000 m for both corridor and wide area applications. The ALS70 operates with a maximum pulse rate up of 500 kHz with multiple returns and intensities, ensuring a high accuracy result.
As well, this LIDAR system has an adaptive roll compensation tool for a full data coverage.
