Geocoding
Turn coordinates into an address, and an address into coordinates.
How Geocoding Works
What is Geocoding?
Putting a name to a point on the earth, or a point to a name. Forward geocoding turns a written address into a latitude and a longitude; reverse geocoding does the opposite, and answers what is at a pair of numbers.
Both directions are the same question asked from opposite ends, so one field takes both. Anything that reads as two numbers is treated as a coordinate, everything else as something written.
How to Use
- Paste a coordinate pair, latitude first:
52.5163, 13.3777. A comma, a semicolon or a plain space all separate the two, and degree signs are ignored. - Or write an address.
Pariser Platz 1, Berlinand350 5th Avenue, New Yorkboth work, because the house number is read at either end of the street. - The part after the last comma is the place to search in. Without a comma the whole line is taken as the name of a town.
- Spelling does not have to be exact.
Hoeninger Weg, Kölnfinds Höninger Weg, andHauptstrfinds Hauptstraße. - A reverse lookup answers with the nearest address and the nearest named place, each with how far away it is. In a city the address is the answer; in open country the distance tells you it is not.
- The dice looks up a random example.
Reading the Distance
Every result says how far it is from the point you asked about. That number is the whole answer to how much the result is worth.
| Under 50 m | The address is the building you pointed at |
| 50 to 500 m | The right street or block, not necessarily the right door |
| Over 500 m | Nothing was mapped nearby. The named place is the better answer |
Coverage is not even. Some places are mapped house by house and others are not mapped that way at all.
What This Does Not Do
- It does not rank by fame or population, beyond preferring a city to a hamlet of the same name.
- It does not search while you type. One query, one answer.
- Where your line fits more than one address, all of them are listed rather than one being chosen.
- It does not show a map. That is deliberate, see below.
- The data is a snapshot of OpenStreetMap, refreshed four times a year.
Privacy & Security: what you type is answered on this server and is never forwarded to a geocoding service. There is no map on this page for the same reason: a map would make your browser fetch tiles from someone else, and your address would reach them along with the request for them.
