GeoAvalanche Avalanche danger index processing
- 2. MYGEOSS 2016 What is GeoAvalanche? Ecosystem of geospatial applications for snow avalanche data able to share information through maps and calculate the risk with a higher level of accuracy and precision Helps users avoiding to visiting places at high avalanche risk by increasing their awareness of snow and avalanche conditions and helps them plan their excursion in safer conditions It exploits an ATES-based innovative algorithm that merges elevation models, crowdsourcing and earth observation data to geoprocessing the risk by doing • Full-text searching for mountain places or peaks which are present in OpenStreetMap data • Navigating different basemaps and then drawing a point or a route • Uploading a GPX track (much more time consuming depending on points number)
