DeFROST Overview

Get a glimpse of how to integrate DeFROST in your website or mobile app.

You can integrate snow data from DeFROST in two main ways:


The DeFROST Maps allow you to display snow cover and depth as a map and integrates quickly with the most popular mobile & web mapping frameworks. Maps are delivered via the Tiled Map Service standard and allows you to customize the look and feel of the tiles on the fly.

You can read through our quickstart to get started with Leaflet, Mapbox, OpenLayers and Google Maps. Check the DeFROST Maps section for an in-depth introduction to the two different snow maps offered: the European Alps map or the Global map.


Do you want to power a custom, more advanced use case? DeFROST API lets you query snow data for a point, along a path or over an area programmatically. Check below for a quick example on a query to find out whether or not there is snow at the top of the Matterhorn:



Obtain the latest snow status data for a specific coordinate expressed in latitude and longitude degrees.

Path Parameters




Latitude measured in degrees



Longitude measured in degrees

    "lat": 45.9766,
    "lng": 7.6585, 
    "snow": true,
    "depth": 1,
    "date": "2019-08-19T12:15:00Z",

The DeFROST API is a RESTful API compliant with the OpenAPI 2.0 standard, so it can be integrated easily in your application. As such you can use it in any environment connected to the world wide web using a TCP/IP library of your choice. The response data format is in the JSON format, which is widely supported by all major programming languages and frameworks. That means you can integrate the API in most platforms including all major web browsers, Android, iOS, Python, C/C++, Node.js. You name it.
