ABSTRACT
American Samoa is slightly larger than Washington, DC. The lowest point is the Pacific Ocean, and the highest point is Lata Mountain. Samoa is slightly smaller than Rhode Island, the lowest point is the Pacific Ocean, and the highest point is Mount Silisili. During the German’s Administration of Samoa early in the 20th century, German surveyors started the first ever surveying system in 1914 and used as the basis for all surveys in Samoa. This triangulation system was established and called the Observatory Origin. Samoa used the Western Samoa Integrated Grid, which was adopted in 1988. The grid was based on the WGS72 Datum with the Western Samoa Integrated Grid.
