GPS Control Data for Benthic Habitat Mapping of the Mariana Archipelago

The goal of the work was to incorporate previously developed mapping methods to produce coral reef habitat maps for American Samoa, Guam and the Commonwealth of the Northern Mariana Islands.

GPS field observations were used to establish the thematic accuracy of this thematic product. Control GPS data was collected on registered survey markers and RMS circular error was calculated to establish the quality of the GPS collected during field surveys.
