ABSTRACT
Dominica is bordered by Guadeloupe to the north and by Martinique to the south. Slightly more than four times the size of Washington, DC, the lowest point is the Caribbean Sea, and the highest point is Morne Diablotins. “Dominica’s first inhabitants, the Ortoroids, arrived from South America around 3100 B.C., and lasted on the island until around 400 B.C. In 1996, the US National Geodetic Survey (NGS) visited the island and performed GPS observations at the airport, but all observations were made only at newly monumented positions by NGS. No local control on the Dominica 1945 Datum was collocated by NGS. There is no currently published information to transform Dominica 1945 Datum to any other datum.
