Geocoding

Geocoding is a tedious operation, based on a huge database of billion addresses in the world associated with a point on a geography map.

Example: Eiffel Tower, Paris (France) has for geolocalization in GPS coordinates: (48.858260, 2.294499)

The addresses are first recorded by the competent groups in each country/territory. Each site or a place name is associated to a position (longitude, latitude) in the cartographic map. Data is then shared (sometimes onerously) for GIS organizations (geographic information system). In recent years free geocoding tools (but limited) have increased thanks to Google Maps and OpenStreetMap.

Specify an address on dCode to receive its GPS coordinates (if the address exists in the database.)

The geocoding process is based on a massive database of addresses data. The working geolocation is only partially automated. An expert called geocoder must complete software tools.

Initially, some addresses are geolocalized manually and the new addresses are encoded on the fly if possible (same street name, same town, same zip-code, infer close location).

Geocoding is an expensive operation that is charged by all geocoding services. Some services share open-data names and locations such as here (link)

The dCode Geocoder is deliberately limited to a few addresses per day and per user.
