Elevations for a list of points

Paste up to 100 points, one per line, as latitude, longitude. Columns copied from a spreadsheet work too.

The same lookup in your app

This page calls the MapSocket Elevation API. Your app can make the same request with a key from your own project: up to 100 points per call, in metres or feet. It's in every plan, including the free Sandbox.

Questions

How accurate are the elevations?
They're interpolated from a global elevation grid: about 30 m between samples over most land, coarser in places and at sea. Expect a few metres of error on gentle ground and more on steep slopes. Sharp summits read low because the grid smooths them: Everest comes out near 8,730 m against its surveyed 8,849 m. Good for maps, route profiles and flood checks; not for surveying.
Where does the elevation data come from?
From Terrain Tiles on AWS Open Data, which combines SRTM, GMTED, ETOPO1 and other open sources. The heights are above mean sea level.
Does it work in the ocean?
Yes. Points at sea return the depth of the sea floor as a negative number, so the middle of the Atlantic comes out several thousand metres below zero.
Can I look up many points at once?
Paste up to 100 coordinates, one per line, and download the results as CSV. Your own app can do the same through the Elevation API: up to 100 points per request.
Can I use this in my own app?
Yes. The Elevation API is in every MapSocket plan, including the free Sandbox. Create a project, copy a key, and call GET /v1/elevation. The request this page makes is shown under the map.
What happens to my location?
The page only asks for it when you press “Use my location”, and only sends those coordinates to the MapSocket API to read their elevation. It isn't added to the page's link.

MapSocket also serves your PostGIS tables as live vector tiles and turns the same shapes into geofences. See every service.
