This digital terrain model of the Icy Bay, Alaska region consists of elevations acquired using airborne Interferometric Synthetic Aperture Radar (IFSAR) merged with bathymetry interpolated from various hydrographic surveys. Hydrographic information for Icy Bay and the lower 9 km of Taan Fiord was primarily from hydrographic surveys and a nautical chart published by the U.S. National Oceanic and Atmospheric Administration (NOAA). Near the head of Taan Fiord, hydrographic survey points were from Meigs and others (2006). The reach of Taan Fiord between the study of Meigs and others (2006) and the NOAA hydrographic data was interpolated using manually drawn contours.
