Coastal Vulnerability to Sea-Level Rise:
A Preliminary Database for the U.S. Atlantic, Pacific and Gulf of Mexico
U.S. Geological Survey
Digital Data Series - 68
The data provided on this CD are
furnished as ArcView shape (.shp, .dbf, .shx) files and Arc export (.e00) files. The shape
files are viewable through a series of project files (.aep) set up for use
with ArcExplorer, a free GIS viewing software available from ESRI.
In addition, the shape files can be accessed through a project file (.prj)
for PC ArcView.
The data are stored in an attribute
table associated with a
1:2,000,000 shoreline at 3 minute resolution. Thus, for each 3 minute (~5
km) section of shoreline, there are data for each of the following
variables -geomorphology, relative rate of sea-level rise, coastal slope, mean
wave height, tidal range and erosion and accretion rates, as well as their
ranked values ( 1 - 5 ) and the
calculated coastal vulnerability index (CVI). These data, with the corresponding metadata, are located in
the Directory DATA,
within the subdirectory corresponding to the shoreline of interest -
Atlantic, Gulf of Mexico, and Pacific. You may either copy the export files directly
from the subdirectory to your GIS workspace, or, once opened following the links below, perform
a "Save As" and save them to your workspace. The base
data provided on this CD-ROM for the states and provinces of the United
States, Canada, and Mexico are derived from ESRI sample data. For further
information about data processing and data sources, please refer to the open-file
The ArcExplorer project files
(.aep), one project file for each of the Atlantic, Pacific, and Gulf of
Mexico Coasts, are located in the DATA\ Atlantic, DATA\Gulf, DATA\Pacific
directories. The ArcView project file (.prj) is located in the DATA
directory and accesses the data for each of the three coasts, Atlantic,
Pacific, and Gulf of Mexico. These ArcView project files were created
in ArcView 3.2 for use with PC ArcView.

file as well as all subsidiary data files. In addition, each folder
(Atlantic, Pacific,and Gulf) contains the .aep project file for each
The ArcExplorer projects
require the installation of ESRI's ArcExplorer 1.1, available for download at http://www.esri.com/software/arcexplorer/index.html.
User Guide is available at the same site. More information on
ArcExplorer and other ESRI products is available at http://www.esri.com.
Once ArcExplorer is installed, the project files (.aep) can be accessed
through the ArcExplorer program. ArcExplorer
is designed for use on the Windows 95/98 and Windows NT platforms.
