My Elevation

What My Elevation is designed to answer

My Elevation is built for people who need a practical answer about my elevation without opening a full GIS package. 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. The result is most useful as a transparent planning or reference output: you can see the inputs, inspect the map where relevant, and compare the answer with related MapBench tools before treating it as a decision.

This page focuses specifically on my elevation and what is my elevation. That distinction matters because nearby tools may use a different geographic model — for example straight-line geometry, road-network travel time, an administrative boundary or a public dataset. Use the method and limitations sections below to understand what the number or map represents before reusing it in a report.

When this tool is useful

Use My Elevation when the question matches the method the page actually uses. Typical workflows include:

• Use the output as a planning or teaching reference, then move to an official or specialist source if the result affects legal, safety, engineering or financial decisions.
• Run the same workflow for locations in different countries while keeping units and assumptions consistent.
• Answer a one-off question about my elevation and keep the result tied to a visible map or explicit input.

Worked examples

These examples are meant to show how to interpret this kind of output, not to replace the values produced from your own inputs.

• 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.

How to interpret the result

The most common errors come from using a correct result to answer the wrong geographic question. Keep these points in mind for My Elevation:

• Remember that elevation models see bare terrain: no buildings, no forest canopy. A line-of-sight 'clear' verdict can still be blocked by a wood, and a horizon distance assumes open ground — treat results as the terrain baseline, then add land cover from local knowledge.
• Include your height inputs explicitly (eye height, mast height, deck level) when sharing visibility results: the same hill answers differently for a child, an adult and a 10 m antenna, and unstated heights make numbers unreproducible.

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.
