Description:

This dataset was developed as a predictive model for locating potential archaeological sites along the California coastline.


The model is based on NOAA's National Geophysical Data Center's (NGDC) high-resolution digital elevation models (DEMs) created for select U.S. coastal regions. (These integrated bathymetric-topographic DEMs are used to support tsunami forecasting and warning efforts at the NOAA Center for Tsunami Research, Pacific Marine Environmental Laboratory (PMEL).


Bathymetric, topographic, and shoreline data used in DEM compilation were obtained from various sources, including NGDC, the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to the vertical tidal datum of Mean High Water (MHW) and horizontal datum of World Geodetic System 1984 (WGS84). Grid spacings for the DEMs range from 1/3 arc-second (~10 meters) to 3 arc-seconds (~90 meters).
