What data source does this tool use?

It uses the Open-Elevation API (api.open-elevation.com), a free, open-source elevation service built on SRTM (Shuttle Radar Topography Mission) data from NASA. No API key is required.

How accurate is the elevation reading?

SRTM data has a horizontal resolution of about 30 meters and vertical accuracy of roughly ±16 meters in most regions. It is suitable for general terrain lookups but not precision surveying.

What coordinate format should I use?

Use decimal degrees — for example, latitude 48.8584 and longitude 2.2945 for the Eiffel Tower. Negative latitude is south of the equator; negative longitude is west of the prime meridian.

Why did I get an error or no result?

The Open-Elevation API is a public free service and may occasionally be unavailable or slow. If the request times out, wait a moment and try again. Also verify that your coordinates are valid (latitude -90 to 90, longitude -180 to 180).

Can I look up ocean coordinates?

SRTM data covers land surfaces only. Coordinates in the middle of an ocean will typically return 0 meters (sea level) or a small negative value.

Try an example

Enter coordinates and click "Get Elevation" to see the terrain altitude.

Summary

Enter latitude and longitude to instantly retrieve terrain elevation in meters and feet via the Open-Elevation API.

How it works

Enter a decimal latitude (e.g. 40.7128) and longitude (e.g. -74.0060).
Click "Get Elevation" to send the coordinates to the Open-Elevation API.
The API returns the elevation in meters for that point on Earth.
The tool converts meters to feet and displays both values side by side.
A Google Maps link opens the exact location in a new tab for visual reference.

Use cases

Determine terrain height for hiking or trail planning.
Check ground elevation before a drone flight.
Validate GIS data or cross-check coordinate datasets.
Find altitude of a specific GPS waypoint.
Research elevation profiles for engineering or construction projects.
Confirm elevation of a city center or landmark for academic work.
