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 42 individual sediment data layers along with
additional basemap data layers have been compiled into an ArcView™ project file (gome.apr) that is located at the top-level directory of this
publication. The project file is intended to be opened and the data viewed with the Environmental Systems Research Institute, Inc.
(ESRI) ArcView or
ArcGIS software. The project file has been modified to reflect relative paths to the archived data as it has been organized for this publication.
To open the supplied project file and view the datasets, the user must
start the appropriate software, navigate to the top-level of this
publication and open the project file (gome.apr).
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
A 'zip' compressed, downloadable archive file containing the components comprising the ArcView 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 ArcView shapefile, the 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 read the shapefile 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.DIRECTORY: data/seddata
