U.S. Geological Survey Digital Data Series DDS-79, Coastal Erosion and Wetland Change in Louisiana: Selected USGS Products
The data supplied on this DVD-ROM are made available with geographic coordinates to allow the data to be incorporated into a Geographic Information System (GIS). The land loss and shoreline change data layers along with additional base map layers have been compiled into an ArcView project file (laproj.apr), which is located at the top-level directory of this publication. The Louisiana base map layers and accompanying unmodified metadata were extracted from the Spatially United Data Sets (SUDS) GIS data repository that is supported in the USGS Coastal and Marine Geology Program's Center for Coastal and Watershed Studies in Florida. The project file was created using ArcView v. 3.2 and requires the MrSID extension which comes standard with ArcView.
For those users without ESRI software or a compatible GIS data browser, the land loss data layers along with additional base map layers have also been compiled into an ArcExplorer project file (laproj.aep) which is also located at the top-level directory of this publication. ArcExplorer is a free GIS viewing software product and is available from ESRI for download at . A User Guide is available at the same site. Once ArcExplorer is installed, the data layers can be accessed through the ArcExplorer program. Please note that ArcExplorer is designed for use on the Windows 95/98/NT/2000 platforms.
Clicking on the layer name under the column header 'Data Layer Name & Description' in the table below will open a new window with a graphical representation of that layer.
'zip' archive file containing the elements that comprise the ArcView shapefile
for each data layer is also provided. The zip files were created using WinZip
v. 8.1. Users may obtain a free copy of the software from
