How it works

Every 24h we process ESA and NASA satellite and ground station data to uncover terrain conditions and risks. Our algorithms calculate a Feasibility Index per trail and activity type.

Satellite data

Every day, we acquire the latest optical and radar data from the Sentinel, Landsat, VIIRS and MODIS family of satellites (operated by NASA and ESA).

Ground data

At the same time, thanks to our partners, we gather ground observer station data on weather and terrain conditions, such as rainfall and snow depth.

Machine Learning

Models on elevation, solar radiation, river catchments and other features give us the context needed to teach the computer to process the data.


A complex geographical data merging and processing algorithm searches for specific terrain conditions on the data acquired: e.g. snow cover, river flows or landslides.


For difficult areas covered by clouds or dense forests, a extrapolation-based statistical algorithm calculates the most likely conditions.

Feasibility Analysis

Based on the terrain conditions and weather forecast, a Feasibility Index is obtained for each trail and type of outdoor activity to be practiced.
