My Elevation

Click the 'Use My Location' button above. When prompted by your browser, grant location permission. GEO MAP TOOLS captures your coordinates and queries the Copernicus Digital Elevation Model (GLO-90) via an internal server service to display your elevation above mean sea level in both metres and feet.

Elevation refers specifically to the vertical distance of the fixed ground surface above mean sea level (orthometric height relative to the geoid). Altitude describes the vertical position of an airborne or flying object (like an airplane or weather balloon) above sea level. Height (or height above ground) measures the vertical extent of a structure, such as a building or tower, relative to the immediate ground surface beneath it.

This tool uses the Copernicus Digital Elevation Model (GLO-90) dataset produced by the European Space Agency (ESA) and Airbus Defence and Space, queried directly via a self-hosted elevation lookup service under the official COP-DEM-GLO-90-F Full, Free & Open license. Copernicus DEM GLO-90 is a global Digital Surface Model derived from satellite radar interferometry (TanDEM-X and TerraSAR-X).

Copernicus GLO-90 is a Digital Surface Model (DSM), not a bare-earth Digital Terrain Model (DTM). Satellite radar waves reflect off the first physical surface encountered — including dense forest canopies, tree crowns, and built urban structures. In dense woodlands, the reported elevation reflects tree canopy heights rather than bare soil, and in metropolitan centers, it can reflect building rooftops.

No. While global validation reports an aggregated absolute vertical accuracy of less than 4 metres LE90 (Linear Error 90%) on gentle terrain, these are statistical benchmarks and do not guarantee point-level accuracy at any individual coordinate. Accuracy can deviate by 10 to 15 metres or more on steep mountain slopes (> 20°) or multi-tiered vegetation canopies.

The elevation data is provided under the official 'Licence for COP-DEM-GLO-90-F Global 90m Full, Free & Open', which explicitly permits free use for commercial applications including ad-supported web tools, with appropriate attribution to the European Space Agency (ESA) and the Copernicus Programme. By implementing a self-hosted raster query engine directly against the open dataset, GEO MAP TOOLS operates without external API rate limits, paywalls, or third-party subscription dependencies.

In the open ocean, a reported elevation of 0 m is a datum baseline convention representing the EGM2008 mean sea-level geoid surface. Copernicus DEM is an overland terrestrial elevation dataset and does NOT measure underwater bathymetry (seafloor depth). Never interpret an ocean reading of 0 m as a measurement of the seabed floor.

Yes. Depressions and dry geological rift basins located below global mean sea level have valid negative elevation values. Famous examples include Badwater Basin in Death Valley, California (-86 m / -282 ft) and the shores of the Dead Sea in Jordan/Israel (-430 m / -1,411 ft), which is the lowest exposed dry land on Earth.

Elevation in feet is calculated using the international foot definition: 1 metre = 3.280839895013123 feet (standard 1 foot = 0.3048 metres exactly). For example, 1,000 metres equals approximately 3,281 feet.

Consumer smartphone GPS chips measure ellipsoidal height relative to the WGS 84 mathematical ellipsoid, which can differ from true mean sea level (the geoid) by up to 100 metres depending on regional planetary gravity variations. Furthermore, satellite geometry produces vertical positioning errors 2 to 3 times greater than horizontal errors, and phone barometer sensors fluctuate with changing weather fronts.

No. GEO MAP TOOLS does not store, log, or track your coordinates in any database. To look up elevation, coordinates are processed solely in volatile memory by our self-hosted server service during your active session and are never saved to disk or tied to user profiles.

Yes. Click 'Share' to copy a direct coordinate link (e.g., '?lat=39.7392&lng=-104.9903'). When opened, the tool restores the coordinates and queries elevation without prompting the recipient for device location permissions.
