Answers to Questions

How to geolocate addresses?

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: Tour Eiffel, 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.

In recent years free geocoding tools (but limited) have increased thanks to Google Maps and OpenStreetMap.
