Summary
In May 2014 the Geophysical Institute at the University of Alaska Fairbanks (UAF) developed integrated bathymetricâtopographic digital elevation models (DEMs) of Skagway and Haines, Alaska, for the National Tsunami Hazard Mitigation Program (NTHMP). The DEMs are designed to fit within a nested hierarchy of similar DEMs of larger spatial extent but coarser resolution. The gridded DEMs will be used to support modeling of tsunami generation, propagation, and inundation. This report describes the various source datasets, data processing tasks and techniques, the surface interpolation, and quality assessment of the seamless 8/15-arcâsecond (~15 m) bathymetric-topographic DEMs. The data files are provided as ASCII raster grids with an [...]
