My Elevation

Press the button for your current elevation from GPS, or search any place on Earth. Elevation is decoded from terrain-model tiles and shown in feet and meters with a visual gauge.

Quick answer: One-tap GPS elevation — how high you are right now, in feet and meters. Coverage: Worldwide. No account is required.

Worked examples

  • Eye height near sea level — With eyes about 1.7 m above sea level, the refracted-horizon estimate is roughly 5 km.
  • 100 m viewpoint — At 100 m elevation above a clear horizon, the estimate increases to roughly 39 km.
  • Antipode example — New York's antipodal coordinate is approximately -40.71, 105.99.

Limits & appropriate use

Terrain intelligence carries one dominant limit: the model sees bare earth at ~90 m spacing with metres of vertical error, and is blind to canopies, walls and wires. Every downstream answer inherits it — profiles show terrain truth with noisy amplitude, line-of-sight verdicts are pending trees, horizons assume open ground, and solar radiation averages assume an unshaded panel. The second limit is temporal: climate letters and hardiness zones are thirty-year character, not this year's behaviour, and seismicity is a mood, not a hazard model. Each result here is printed with its recipe precisely so these boundaries travel with the number.

The value proposition is screening-grade truth at zero cost: orientation for sites, gardens, antennas, shoots and curiosity, with the upgrade points clearly marked. When money or safety attaches to the answer — tower siting, flood insurance, structural shading, avalanche terrain — the escalation is professional: licensed survey, certified shade studies, regulatory flood determinations and geological hazard services. A good free tool makes that ladder visible instead of pretending to be the top of it.

  • Construction and tower siting → licensed topographic survey.
  • Flood decisions → regulatory determinations (FEMA/FIRM in the US).
  • Solar finance → certified shade and production studies.

Data & methodology

Elevation and radiation use Open-Meteo's open API on Copernicus/ERA5 datasets; visibility math adds standard refraction (k = 0.13). US hydrology/flood layers come from USGS and FEMA public services.

Frequently asked questions

How accurate is the reading?

Elevation comes from a single 30 m terrain-model pixel (Terrarium tiles, SRTM/ASTER based) — good for trip planning, not survey grade.

Why does it differ from my phone's altitude?

Phone GPS altitude can wander by 10–30 m, especially indoors or in cities; the tile value is the modelled ground height.

Can I check elevation without GPS?

Yes — search any place or click the map for the same lookup.

Does it work below sea level?

Yes — negative values like the Dead Sea (−430 m) are shown correctly.

Is my location sent anywhere?

No — the GPS reading stays in your browser; only the public elevation tile is fetched.
