ABSTRACT
The original inhabitants of Guinea were forced out of the area around 900 A.D., and numerous kingdoms were subsequently established. The Federation of French West Africa, which included Guinea as a member, was established in 1895. Guinea includes the Los Islands, an island group west of the capitol city of Conakry. The Guinean Maritime boundary is defined in large part by a single, unique Straight Baseline. The boundary between Guinea and Guinea-Bissau was established through a Franco–Portuguese convention of May 12, 1886. The Guinea–Sierra Leone boundary has a length of approximately 648 km. There have been some other rather curious coordinate systems devised for Guinea during the twentieth century. French Navy Hydrographic surveys of the late 1940s in Guinea were cast on the Fuseau Senegal Grid. As of September 30, 1950, all new surveying and mapping of French Guinea was done on the Universal Transverse Mercator Grid.
