Glacier World Map

About Glacier World Map 🧊

Glacier World Map charts the glaciers of the world — valley glaciers, icefields and the shrinking remnants high in mountain ranges — making visible a part of the landscape that is changing faster than almost any other.

Glaciers come from OpenStreetMap's `natural=glacier` tag, mapped from survey and satellite data. Glacier travel demands proper equipment and experience: this map shows where ice is, never that it's safe to walk on.

Who is behind this site?

Glacier World Map is built and maintained by Emil Björk, an independent developer based in Sweden. The site grew out of a passion for maps, travel and open data, alongside a professional background in IT consulting.

How it works

Every point is fetched from the OpenStreetMap Overpass API, deduplicated, tagged by country and stored as a static GeoJSON file — no database, instant to load. Click any point to see a description from Wikipedia, a photo from Wikimedia Commons (or Mapillary as a fallback) and, where available, its Google rating.

Data freshness

The dataset is automatically refreshed once a month from OpenStreetMap via a scheduled GitHub Action, so the map stays current as the world is mapped.

Spot something missing?

This map is only as complete as OpenStreetMap itself. If you know a glaciers that isn't here, you can add it directly to OpenStreetMap — it's free, open and will appear here at the next refresh.

New to OpenStreetMap? See the how-to-tag guide for glaciers. Edits show up here at the next monthly refresh.

Report an error or a wrong location

Found a glaciers in the wrong spot, with outdated details, or listed twice? The data lives in OpenStreetMap, so the quickest fix is a short note there — a local mapper reviews it and the correction flows back to this map at the next refresh.
