Appendix Geospatial Data

Skip past contents information

This appendix describes the data collected for this project, the location of the data, and how to access the data.

Data Format and Projection
All vector data are delivered as Esri shapefiles in the geographic coordinate system (WGS 84). The raster data are in GeoTIFF and Esri grid formats in Universal Transverse Mercator (UTM), Zone 19N, WGS 84 projection. These data can also be accessed through the U.S. Geological Survey Coastal and Marine Geology Program Web Map server (http://coastalmap.marine.usgs.gov/).

All spatial data are distributed with Federal Geographic Data Committee (FGDC) compliant metadata in 4 formats—extensible markup language (XML), text (TXT), hypertext markup language (HTML), and frequently asked questions html (FAQ). Esri ArcCatalog 9.x can also be used to examine the metadata in a variety of additional formats.

Data Access
The complete datasets from this project can be accessed in the following ways, depending on available software:

  1. With ArcGIS 9.2 or later, all shapefile and raster data may be viewed and manipulated, although the Spatial Analyst extension will be required to fully examine and work with the Esri grids. Download the GIS_catalog.zip file (585 megabytes) to a computer and open the ArcMap document 2013_1020.mxd. This map document has all the data layers loaded in the table of contents and uses relative links.
  2. Without any geographic information system (GIS) software, view the data through ArcReader, a free mapping application distributed by Esri for Windows, Linux, and Unix operating systems. Download ArcReader from the Esri Web site (http://www.esri.com/software/arcgis/arcreader/download.html) and follow the directions for downloading and installing the free software. Once ArcReader is installed, all the data can be viewed by opening the published map file (PMF) named 2013_1020.pmf, which was created in ArcMap version 9.3.1.

Data Organization
The data are organized in folders on the Publications Warehouse web site. Data layers can be downloaded individually using the table below or collectively from the GIS_catalog.zip file.
