European Alps Map

Daily updated snow cover map at 20 meters resolution

The Alps are the highest and most extensive mountain range system that lies entirely in Europe, and stretching approximately 1,200 kilometres across eight Alpine countries: France, Switzerland, Monaco, Italy, Liechtenstein, Austria, Germany, and Slovenia.

Due to the key importance of this area in Europe and globally in terms of population, visitors and human activity, DeFROST operates and serves a daily snow cover map with 20 meters resolution for its extent.

If you make any request for a tile outside the above covered area, the DeFROST server will return a 404 Not Found response code.
