About Where Am I Tool

Where Am I Tool answers "where am I?" in one tap: your street address, city, county, state, ZIP code, coordinates and ground elevation, together on one screen. We built it because every other site we tried answered one of those questions per page, loaded a heavy map before showing anything, and rarely said where its numbers came from or how far to trust them.

Where the data comes from

• Your position comes from your own device, through the standard browser location feature, only after you allow it.
• Addresses, cities, counties, states and postcodes come from OpenStreetMap, the open map built by volunteers and public data imports, through its Nominatim search service. OpenStreetMap data is © OpenStreetMap contributors and available under the Open Database License.
• Ground elevation comes from the AWS Terrain Tiles open dataset, which in the United States is based on the USGS 3D Elevation Program and elsewhere on global sources such as the Shuttle Radar Topography Mission. We tested it against the USGS's own elevation service before launch: a point in downtown Denver read 1,596.7 metres from the tiles and 1,596.4 metres from USGS.
• Map images are OpenStreetMap's standard tiles.

How accurate it is

The position is only as good as your device's fix, which is why every result shows an accuracy radius. Outdoors on a phone that is usually a few metres; indoors or on a laptop it can be hundreds. The address is the nearest mapped address to that position, so in rural areas or large buildings it can name a neighbour. The elevation data is generally good to a metre or two in the United States and several metres elsewhere.

For anything with legal weight, such as a property boundary, a flood elevation certificate or the county that taxes a parcel, use the official record: a licensed surveyor, your county assessor or the USPS. We say so on the pages where it matters.

Privacy

There is no account, no database and no server of ours in the path of your location. The page runs in your browser, which fetches the address and elevation directly from the services above, and the result is gone when you close the tab. The privacy policy lists exactly which services receive a request.

Who runs it

Where Am I Tool is a small independent project run from India by a software engineer who builds single-purpose web tools. It is free to use and free to embed on your own site. If a result looks wrong for a specific place, or you have an idea for the site, write to hello@whereamitool.com. Reports that include the coordinates from the result are the quickest to check.
