Jasná SNOWsat

Ski Slope Maintenance Management System

Project:

- DTM and DOFM updates for the SNOWsat system and the northern part of Jasná ski resort system

- Digital colour-coded orthophoto map of the Jasná territory, Slovakia 

- Classified point clouds

- Digital terrain model 

- Topologically trimmed ski slopes for the SNOWsat system update

Technology:

- Digital colour orthophoto map of the Jasná territory with the following parameters: time-stamped of 2017 (16.10.2017), 0.10 m/pixel resolution, RGB, Datum of Uniform Trigonometric Cadastral Network (S–JTSK), Baltic Vertical Datum – After Adjustment (BpV), UTM34N coordinate system, ellipsoid height, TIFF + TFW formats

- classified point clouds, Datum of Uniform Trigonometric Cadastral Network (S–JTSK), Baltic Vertical Datum – After Adjustment (BpV), UTM34N coordinate system, ellipsoid height, LAS, LAZ formats

- Digital terrain model with a regular 1-metre grid, Datum of Uniform Trigonometric Cadastral Network (S–JTSK), Baltic Vertical Datum – After Adjustment (BpV), UTM34N coordinate system, ellipsoid height, XYZ format

- Topologically trimmed ski slopes for the SNOWsat system update, Datum of Uniform Trigonometric Cadastral Network (S–JTSK), Baltic Vertical Datum – After Adjustment (BpV), UTM34N coordinate system, ellipsoid height, SHP format

Outputs:

SNOWsat is a professional satellite-guided snow and fleet management system. Thanks to the GPS and information obtained from the digital terrain model,  the SNOWsat system can detect the exact depth of snow beneath the vehicle while grooming a ski slope. SNOWsat LiDAR registers the snow depth a whole 10 – 40 meters in front of the pusher blade.  Therefore, the operators can control the pusher blade even more accurately, move the snow where necessary and spread it more efficiently, providing better slope maintenance. As a result, the slope's operations are optimised, grooming vehicles and snow cannons monitored, and the snow and vehicle fuel consumption are economised, bringing considerable savings in overall operational costs.
