Readme for Hawaii_Landsat_Mosaic_Bathymetric_Fill.jp2 This satellite image mosaic covers all the main Hawaiian Islands with a bathymetric shaded relief image filled into the ocean areas. The land imagery are composites of multiple images from the Landsat satellite and are substantially cloud-free. They were produced in true color (using bands 3, 2 and 1) and pan-sharpened using band 8 to produce a spatial resolution of 15 meters. The imagery was then resampled to 12.5 meters. The bathymetric (ocean depth) data is derived from the Main Hawaiian Island Bathymetric Data Synthesis dataset developed by the Hawai'i Mapping Research Group (http://www.soest.hawaii.edu/HMRG/cms/). A color shaded relief image was produced from a 2010 version of the HMRG dataset and a land/ocean mask was used to integrate the Landsat imagery and bathymetry into a single image.
