| (documentation NullIsland EnglishLanguage "NullIsland Null Island is the location at zero degrees latitude and zero degrees longitude (0°N 0°E), i.e., where the prime meridian and the equator intersect. Since there is no landmass located at these coordinates, it is not an actual island. The name is often used in mapping software as a placeholder to help find and correct database entries that have erroneously been assigned the coordinates 0,0. The point on the Earth's surface defined as Null Island is located in international waters in the Atlantic Ocean, roughly 600 kilometres (320 nmi) off the coast of West Africa, in the Gulf of Guinea. A weather buoy, named the Soul buoy after the soul music genre, was moored at the location.[Wikipedia]") | Geography.kif 6766-6774 | |
