Slope grid derived from 10m gridded bathymetry of Alamagan Island, Commonwealth of the Northern Mariana Islands (CNMI), USA
Description
Slope is derived from gridded (10 m cell size) multibeam bathymetry, collected aboard NOAA Ship Hiialaka'i and R/V AHI. Cell values reflect the maximum rate of change (in degrees) in elevation between neighboring cells derived with the ArcGIS Spatial Analyst extension. This data set is for the shelf and slope environment of Alamagan Island. CNMI and Guam slope maps are all symbolized with the same classified color ramp (with the exception of a unique maximum value) in order to provide a standard for qualitative comparisons between islands.
