This section describes the qualitatively derived data interpretation files, the location of the files, and how to access the data.
Data Format and Projection
Vector data are delivered as Esri shapefiles in the Geographic Coordinate System, referenced to the World Geodetic System of 1984 (WGS 84). Raster data from Pendleton and others (2013) are in the Universal Transverse Mercator Horizontal Coordinate System referenced to WGS 84, and the elevation data are relative to the North American Vertical Datum of 1988. Spatial data are distributed with Federal Geographic Data Committee (FGDC)-compliant metadata in text and FGDC Classic and FAQ (in hypertext markup language [HTML]) formats. Esri ArcCatalog can also be used to examine the metadata available in the Esri extensible markup language (XML) format associated with each geographic information system (GIS) data file.
The datasets from this report can be accessed in the following ways, depending on available software:
The data from this report are organized in folders. Links to source data published by Pendleton and others (2013) are included in the table below to provide easy access to related layers.
