Rugosity grid (5 m) derived from gridded bathymetry of Saipan Island, Commonwealth of the Northern Marianas

Metadata Updated: February 7, 2018

Rugosity is derived from gridded (5 m cell size) bathymetry from two sources: Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and NOAA Ship Hi'ialakai; multibeam bathymetry collected aboard the US Naval Ship Sumner by the Naval Oceanographic Office, and lidar, also collected by the Naval Oceanographic Office. Rugosity is derived using the Benthic Terrain Modeler with rugosity methods by Jeff Jenness (2003). Cell values reflect the (surface area) / (planimetric area) ratio for the area contained within that cell's boundaries. They provide indices of topographic roughness & convolutedness. This data set is for Saipan Islands, Commonwealth of the Northern Marianas (CNMI).
