I am looking for sources of geo-referenced data on villages and cities (or all other things there are) in The Gambia (and Senegal if available).
I was able to acquire some 1000 Gambian coordinates from HERE maps, Google maps, and MapQuest, though the respective APIs. But I estimate that this is missing roughly halve of the villages in The Gambia. What is more. Some of these one thousand are rather bad/uncertain matches, so it would be good to compare with additional sources.
Are there any other sources, with a decent level of detail and fairly up-to-date.
