Lidar provides exact measurements for the 46 th FIS Alpine World Ski Championships Cortina d’Ampezzo, February 8-21, 2021.
A long period of preparation is required to stage an alpine event like the FIS Alpine World Ski Championships. With a single goal, the ski slopes will be available to the athletes on day X in the most ideal condition possible for their hunt for medals. In order for this to happen, many highly diverse points have to work together perfectly.

The South Tyrolean company, Alto Drones GmbH , made a significant contribution to this by surveying the site of the FIS Alpine World Ski Championships in Cortina d’Ampezzo. The exact measurement data for the detailed evaluations were provided by the integrated RIEGL miniVUX-1UAV used by Alto Drones on a Soleon LasCO UAV.
Resource management does not stop at ski resorts, and so in recent years there has been increased investment in snow depth measurement with RTK-GNSS on snow groomers. This provides the snow groomer operator with a continuous display of the snow depth under the tracks. This allows the snow groomer to optimally prepare the slope and shift snow amounts so that the slope does not prematurely snow out, and this helps the snow groomer to clear roads and paths of snow at the end of the season. As a basis for these systems, a survey of the terrain without snow is necessary. This is usually carried out between September and November.
Thomas Fontana, founder and CEO of Alto Drones, who has been successfully performing such surveys with UAVs for several years now states, “Due to the dimensions of the project areas, usually a maximum of 400 km 2per ski resort, we have seen in recent years that the miniVUX-SYS systems are perfect for this task: We can cover up to 250 ha of area per day, depending on the terrain conditions, and have been able to roughly triple our performance compared to the “pre-RIEGL miniVUX” way of working. There are many reasons for this: On one hand, the small number of control points necessary to achieve the required accuracy of +/- 5 cm significantly reduces field work. On the other hand, the optimal data density of about 100-200 pts / m² provides sufficient accuracy to model terrain edges accurately – but is low enough that the evaluation is very fast and usually a classified point cloud is available the day after the flight. ”
In addition, updating the data is much more cost-effective than when using helicopters or airplanes, since aerial surveys are worthwhile even for small areas (e.g., after construction work, landslides, new slopes) and the data can be integrated very easily into the overall terrain model.
