U.S. Geological Survey Open-File Report 2009–1003
Digital Seismic-Reflection Data from Eastern Rhode Island Sound and Vicinity, 1975–1980
This report contains seismic-reflection data presented in TIFF, PNG, GIF, and SEG-Y formats. Ancillary vector data, including navigation point and trackline files and a National Oceanic and Atmospheric Administration polygon shoreline, are presented in Environmental Systems Research Institute (ESRI) shapefile format. These vector files are provided in the Geographic Coordinate System in the WGS84 datum. Shot-point text files are in Universal Transverse Mercator projection, zone 19, WGS84 datum, in a format that can be imported into a Landmark seismic-interpretation package.
The top level of Disk A of the DVD-ROMs contains an ArcView 3.3 project file (eris_seis.apr) and an ESRI ArcMap document (eris_seis.mxd) created in ArcMap 9.2, but saved as an ArcMap 9.0/9.1 document to make it accessible in older versions. These files contain the data layers of this report already loaded. If the user does not have access to the ESRI software or a compatible GIS data browser, a free viewer, ArcExplorer, is available from ESRI.
Each GIS data layer from this publication is cataloged below for easy access. The individual data layer name is linked to a browser graphic that will open in a separate browser window and display an image of the data layer. Federal Geographic Data Committee metadata for the individual data layers are provided in HTML, FAQ HTML, and text versions. Selecting associated metadata files from the table below will open the information in a new browser window.
A compressed Zip, downloadable archive file containing the components of each data layer is also provided. Compressed, downloadable files were created by using the Windows program WINZIP v9.0. Users who do not have software capable of uncompressing the archived Zip files can obtain a free version of the software from Pkware, Inc.
TIFF, PNG, and SEG-Y files are linked to the cruise's Seismic Profiles page, where there are instructions in the data listing for downloading the data.
