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.

To display the DeFROST European Alps snow cover map as a layer over the base map of your choice, use the URL string below as the Tile Server endpoint:
https://maps.defrost.io/{z}/{x}/{y}.pngPay attention to the fact that as any DeFROST endpoint, JWT Authentication is required for the Tile Server. This means a valid JWT token has to be set in the HTTP Authorization request header. Read more about Maps Authentication in the Maps Overview section.
