Elevation Finder
Find the height above sea level of any latitude/longitude — or your current GPS location. Free, SRTM-based (30 m resolution), runs in your browser.
Tip: the default coordinates are Mt Everest's summit (8,848 m). Click anywhere on the map to look up that point's elevation.
Notable elevations
- Everest summit — 8,848 m (29,032 ft), the highest point on Earth.
- Dead Sea shore — -430 m (-1,411 ft), the lowest land on Earth.
- Denali summit — 6,190 m, the highest peak in North America.
- Sea level — 0 m, the reference for all elevations.
Frequently Asked Questions
How does the elevation finder work?
It calls the free Open-Elevation API, which returns the height above sea level at any latitude/longitude using a global digital elevation model (SRTM-based, ~30 metre resolution near the equator). For points in the United States the data comes from USGS; globally it comes from the Shuttle Radar Topography Mission flown in 2000.
How accurate is the elevation?
Within about ±10 metres for most land points, limited by the underlying DEM resolution. Buildings and trees can add a few metres of error since the radar measured the surface, not the ground. Over open water the API returns 0 (sea level). For survey-grade work you'd need a local LiDAR dataset.
Can I find the elevation of my current location?
Yes — click "Use My Location" and the browser will share your GPS coordinates with the tool. Phones with a barometric sensor report their own altitude too, but this tool returns the DEM value, which is more consistent and doesn't depend on weather.
Why does my phone show a different elevation than this tool?
Phones use a barometer (air pressure) to estimate altitude, which drifts with weather and is less accurate in aircraft or tall buildings. This tool returns the geodetic height from radar-mapped terrain data, which is the value you'd see on a topographic map for the same spot.
