By 2021, 18 LIA® laser scanners had been installed worldwide.
- 3D Laser measurement of changes in the snow accumulations in the avalanche release area (initiated by snowfall, wind and avalanche releases)
- Completely Autonomous Operation
- Easy to mount: attachable to Wyssen avalanche towers LS12-5 and LS6-5
- Low cost due to using power supply and data connection from the Wyssen Avalanche Tower
LIA® scans the surface of the snow-cover in customizeable intervals. Each scan collects up to 44’000 points. Each point represents a distance from the snow cover (or any other object) to the scanner unit. These measurements are then immediately sent to the servers to be evaluated. The illustration on WAC.3® is a powerful tool which helps to measure not only snow height over time at different points but also lets you see the distribution of snow as well as results of avalanche control and even natural releases.
