This document describes the contents of a digital data base that may be used to identify coastlines along the U.S. West Coast that are at risk to sea-level rise. This data base integrates point, line, and polygon data for the U.S. West Coast into 0.25° latitude by 0.25° longitude grid cells and into 1:2,000,000 digitized line segments that can be used by raster or vector geographic information systems (GIS) as well as by non-GIS data bases. Each coastal grid cell and line segment contains data variables from the following seven data sets: elevation, geology, geomorphology, sea-level trends, shoreline displacement (erosion/accretion), tidal ranges, and wave heights. One variable from each data set was classified according to its susceptibility to sea-level rise and/or erosion to form 7 relative risk variables. These risk variables range in value from 1 to 5 and may be used to calculate a Coastal Vulnerability Index (CVI). Algorithms used to calculate several CVIs are listed within this text. The data for these 29 variables (i.e., the 22 original variables and 7 risk variables) are available as:
These data are available as a Numeric Data Package (NDP) from the Carbon Dioxide Information Analysis Center (CDIAC). The NDP consists of this document and machine-readable files available on 8-mm tapes, quarter inch tape cartridges, IBM-formatted high-density floppy diskettes, and CD-ROM. These files are also available through the Internet using the File Transfer Protocol (FTP) from CDIAC's anonymous FTP area which can be accessed directly (cdiac.esd.ornl.gov) or through the World Wide Web (WWW) at http://cdiac.ess-dive.lbl.gov/. This document provides sample listings of the data and detailed descriptions of the file formats; offers FORTRAN and SAS retrieval program listings; describes the methods used in calculating each variable; discusses the sources, restrictions, and limitations of the data; provides five ARC/INFO export coverages and flat ASCII data files containing these data; and reprints of pertinent literature.
