This data set consists of ASCII raster grids of various resolutions representing bathymetric
and topographic data values relative to Mean High Water for the Seaside-Gearhart and
greater Pacifc Northwest region. These grids were developed for use in tsunami inundation
modeling.
This data set is one of a collection of spatially referenced digital files in a geographic information system related to the Seaside, Oregon, Tsunami Pilot Study.
Federal Emergency Management Agency (FEMA) Federal Insurance Rate Map (FIRM) guidelines do not currently exist for conducting and incorporating tsunami hazard assessments that reflect the substantial advances in tsunami research achieved in the last two decades (Tsunami Pilot Study Working Group, 2006). Therefore, as part of the FEMA Modernization Program, a Tsunami Pilot Study was carried out in the Seaside/Gearhart, Oregon, area to provide information from which tsunami mapping guidelines could be developed. This area was chosen because it is typical of coastal communities in the section of the Pacific Coast from Cape Mendocino to the Strait of Juan de Fuca. There was also considerable interest shown by state agencies and local stakeholders in mapping the tsunami threat to this region. The study was an interagency effort by scientists from the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, the University of Southern California, and the Middle East Technical University. We present the GIS data from that report in this publication.
These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information.
The data sets consists of 3 ASCII raster grids covering the Seaside, Oregon, Oregon-Washington coastal area, and Pacific Northwest, region, with resolutions of 1/3 arc-seconds, 6 arc-seconds, and 36 arc-seconds. The 1/3 arc-second grid consists of bathymetric and topographic values. The lower resolution grids consist of values representing bathymetry only.

Complete.
The horizontal accuracy of each grid is expressed as an estimated root mean square
error (RMSE). The estimate of the RMSE is based on horizontal accuracy tests of
the source data which are selected as equal to or less than the intended horizontal
RMSE error of each grid. Horizontal positioning of the various source points were
compared with each other to verify grid accuracy.
The vertical RMSE is used to determine vertical accuracy of the grid. It accounts
for systematic and random errors. Refer to Venturato (2005) cross reference.
