GIS Data Layers

Data in this publication are intended to be integrated into a GIS. A GIS is defined as a system of hardware and software to support the display, manipulation, and analysis of spatial data for mapping and complex data analysis. This integrated package provides researchers the ability to integrate, analyze and map the various datasets to help with economic and social policy-making decisions regarding the environment.

Individual data layers for this publication along with additional basemap layers have been compiled into an Internet Map Server. The Coastal and Marine Geology Internet Map Server, viewable at http://coastalmap.marine.usgs.gov/, brings the usefulness of a GIS into your computer via a web browser. An introduction and help page for the Internet Map Server is available at http://coastalmap.marine.usgs.gov/ArcIMS/aimshelp/.

There are nine GIS data layers (shapefiles) offered for each state along the U.S. Southeast Atlantic Coast. These include: four vector shorelines, an offshore baseline used for generating shore-normal transects, transects for long- and short- term shoreline change rates, transect/shoreline intersection positions, and a vector layer to show the spatial extents of beach nourishment projects. The GIS data layers from this publication are cataloged below by state for easy access.

Federal Geographic Data Committee (FGDC) compliant metadata for the individual data layers are provided in HTML format. Selecting associated metadata files from the table below will open the information in a new browser window.

A 'zip' compressed, downloadable archive file containing the components of the ArcView shapefile for each data layer is also provided. Compressed downloadable files were created using the Windows program WINZIP v8.1. For those users who do not have software capable of uncompressing the archived zip files, they may obtain a free version of software from Winzip Computing, Inc.
