Abstract The National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), has developed two bathymetric-topographic digital elevation models (DEMs) of Port Townsend, Washington. A 1/3 arc-second DEM referenced to North American Vertical Datum of 1988 (NAVID 88) was carefully developed and evaluated. As NAVID 88 to mean high water (MHW) 1/3 arc-second conversion grid was then created to represent the relationship between NAVD 88 and MHW in the Port Townsend region. A 1/3 arc-second MHW DEM, combining the NAVD 88 DEM and the conversion grid, will be used as input for the Method of Splitting Tsunami (MOST) model developed by the Pacific Marine Environmental Laboratory (PMEL) NOAA Center for Tsunami Research (http://nctr.pmel.noaa.gov/) to simulate tsunami generation, propagation and inundation. The NAVD 88 DEM was presented from diverse digital datasets in the region. The MHW DEM will be used for tsunami inundation modeling, as part of the tsunami forecast system. Short-term Inundation Forceasting for Tsunamis (SIFT) currently being developed by PMEL for the NOAA Tsunami Warning Centers. This report provides a summary of the data sources and methodology used in developing both Port Townsend DEMs.
