Mosaic of gridded multibeam bathymetry and bathymetry derived from multispectral World View-2 satellite imagery of Rota Island, Territory of Mariana, USA
Gridded multibeam bathymetry is integrated with bathymetry derived from multpectral World View-2 satellite data. Gridded (5 m cell size) multibeam bathymetry collected aboard NOAA Ship Hiialaka'i and R/V AHI. Multibeam data were also collected aboard the NOAA Ship Oscar Elton Sette in 2010, a 224? (68 m) United States National Oceanographic and Atmospheric Administration research ship. Bathymetry values shallower than ~20 m were derived by gauging the reletive attenuation of coastal, blue, green and yellow spectral radiance as a function of depth. A multiple linear regression analysis of coastal,blue, green and yellow band spectral values against depth determined the variables of y-intercept, coastal,blue, green and yellow slope values. Variables then used in multivariate slope intercept formula to derive depth. Digital image processing to derive depths conducted with the ENVI 4.8 software program while data editing and integration was performed using ArcGIS 10. This data set is for the shelf environment of Rota Island, Mariana.
