USGS East-Coast Sediment Analysis: Procedures, Database, and GIS Data
By McMullen, K.Y., Paskevich, V.F., and Poppe, L.J.
Data on this publication are provided with geographic coordinates to allow the data to be integrated into a Geographic Information System (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 solving. 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.
The data in this version of the publication have been updated from Poppe and others (2005). Errors in the previous version have been corrected and samples analyzed between 2005 and 2011 have been appended to the database. A suggested citation for the new version of the database is:

This project uses the Environmental Systems Research Institute's (ESRI) ArcView™ and ArcGIS™ software as its Geographic Information System (GIS) mapping tool. Data layers archived here should not require additional processing to be utilized within the ESRI software. This does not mean that a user will not wish to do additional processing, especially if utilizing a different GIS software package or spheroid, but that it is not necessary to do additional processing simply to utilize the data in its minimum archive format
For those who don't have the
software or a compatible GIS
data browser available on their computer, a free viewer,
ArcExplorer™, is available from
ESRI. Currently ArcExplorer™ version
9.1 software is available for Microsoft Windows, UNIX, and Linux
ArcExplorer™ version 9.0 is available for the
Macintosh OS X platform. There is no prepared project file for use with
ArcExplorer™. If the user chooses
ArcExplorer™, it will be necessary to add the
selected data layers to their defined project file.
Federal Geographic Data Committee (FGDC) metadata for the individual data layers is provided in three versions (HTML, FAQ, text). Selecting associated metadata files from the table below will open the information in a new browser window. An "Extensible Markup Languge" (XML) version of the metadata are also available in the individual data directories. This version of the metadata is made available for use with ESRI's ArcCatalog software.
A 'zip' compressed, downloadable archive file containing the elements comprising the ESRI shapefile for each data layer is also provided. Compressed downloadable files were created using the Windows program WINZIP v8.0. For those users who do not have software capable of uncompressing the archived zip files, they may obtain a free version of the software from Winzip Computing, Inc. or Pkware, Inc. In addition to the ESRI shapefile, the surficial sediment data layers are available in an ASCII text format and Microsoft Excel spreadsheet formats to allow users who may not have access to GIS software to have access to the source data in an alternate way to view and examine the datasets. The first record of the ASCII file and Excel spreadsheet contains the name of the data fields for that file.
