High Resolution Coastal Data for Hawaii

JALBTCX has collected valuable datasets in the state of Hawaii in 1999, 2000, and 2007. Applications for the data include coral reef mapping, tsunami modeling, and nautical charting. In 1999 and 2000, SHOALS measured bathymetry on a 4- by 4-m grid for all of Maui, Oahu, and Kauai, the western shore of Hawaii, and the southern shore of Molokai. The data were delivered in XYZ ASCII format and paper map sheets. In 2007, CHARTS measured topography on a 1- by 1.5-m grid on the northern shores of Maui, Oahu, Kauai, Hawaii, and Molokai. The data were delivered in LAS format with several derived digital information products including first and last return DEMs, bare earth models, coverage maps, RGB orthomosaics and hyperspectral image mosaics. Advanced digital data products like the basic land cover classification and color-balanced mosaic were generated using a combination of the lidar data and hyperspectral imagery.
