Nigeria. As a regional map, the detail provided is unsurpassed by any other map of this part of the world. It is the most detailed map to date of the West African states of Guinea, Guinea-Bissau, Liberia, and Sierra Leone. As is always the case with Africa, road information is presented in practical terms of road quality, not road designation. This is a practical map for travellers, so information has been provided with the greatest degree of accuracy possible, given that reliable information can be extremely difficult to determine. This is very much a map in progress, and we would welcome comments about it to assist future editions. The spelling of place names is as would be known in English, so Cote D´Ivoire is Ivory Coast.
