OpenStreetMap

OpenStreetMap is a free project for the joint development of public maps and diagrams of cities, streets, roads with the help of manual or automatic data entry, as well as obtaining data from portable GPS-receivers.
The project site runs on the MediaWiki engine, similar to Wikipedia.

A map of the whole world in 3D.
The OpenStreetMap database is used, which also indicates the number of storeys of buildings, which helped to create a map in 3D.

There are no photos of buildings on maps, which would simulate reality, but it is faster loaded and covers the whole world, even small settlements, due to this number of storeys, the ratio of buildings is quite correct and recognizable.
