Site Location Information City or Town : Yamoussoukro State or Province : Country : Cote d'Ivorie Tectonic Plate : African Plate Approximate Position (ITRF) X coordinate (m) : 6306440.2132 Y coordinate (m) : -578381.0131 Z coordinate (m) : 757956.3277 Latitude (N is +) : +065214.16 Longitude (E is +) : -0051424.36 Elevation (m,ellips.) : 270.4983 Additional Information : The GPS station is located in Yamoussoukro : about 250 km NNW of Abidjan in the Republic : of Ivory Coast. The marker is encased on : top of a prominent 5 m concrete pillar : across from the ENESTP, about 5 km NNE of : the downtown area. The pillar is adjacent : to an enclosed building housing the GPS : receiver and ancillary equipment. The base : computer is located in the FHB Fondation : building. The mark is atop a 3 mm nob : physically present on the surface of the : plate. 3.
