OpenStreetMap

Compare to Google Maps

Google Maps be considered a major provider for "free" map services. Unfortunately Google as well as Yahoo seem only focus on the "developed world". Especially on city level, the OpenStreetMap project already provides a higher accuracy.

Google Maps

Addis Ababa: OpenStreetMap vs Google Maps: compare
Google Maps features only very few major roads. The placement is highly inaccurate.

Ethiopia: OpenStreetMap vs Google Maps: compare
Google Maps features the major roads. On OpenStreetMap many roads are missing - but the existing ones are mostly very accurate.

Yahoo Maps

Yahoo seems to use the same data as google. Within Addis Ababa Yahoo obviously just connected the major roads in the city center. compare
