Tongues from Space Glacier sizes Drag a Swiss glacier onto a city and see how big it is.

Tongues from Space Glacier sizes

How big is a glacier? All ten glaciers lie where they really are. Pick one or two, drag them onto a city (or type your own) or onto each other, and turn them with the round handle.

01Glacier

Click a glacier here or on the map. The last two you pick are compared on the right. The outlines are the latest available ones, from the Swiss Glacier Inventory SGI2023 (state of 2023; Unteraar and Trift 2024; GLAMOS). The glaciers have shrunk since.

02Compare with a city

City outlines are the municipal boundaries (swissBOUNDARIES3D), so they include lake area where the boundary does. A city you type comes from OpenStreetMap (administrative boundary, © OpenStreetMap contributors, ODbL, found with Nominatim).
