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.
