Abstract
|
In September 2010, the National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), developed three bathymetric-topographic digital elevation models (DEMs) of Southeast Alaska. The DEMs were developed for the National Tsunami Hazard Mitigation Program (NTHMP; http://nthmp.tsunami.gov/) in support of the State of Alaska's tsunami inundation modeling efforts led by the Geophysical Institute at the University of Alaska at Fairbanks (UAF). The DEMs are nested at 8 arc-second, 8/3 arc-second, and 8/15 arc-second, with the highest resolution grid centered on the harbor at Juneau. The coastal DEMs will be used as input for the university-developed modeling system to simulate tsunami generation, propagation, and inundation (http://www.aeic. alaska.edu/tsunami/). The DEMs were generated from diverse digital datasets in the region (grid sources shown in Fig. 7) and were designed to represent modern morphology. This report provides a summary of the data sources and methodology used to Southeast Alaska DEMs.
