Geospatial Data


A total of 33 data layers are included in this online open-file report. Detailed descriptions of the geospatial data layers are provided in the metadata files. Twenty-four of the layers have associated metadata files. For more information on the data layers, also see the map text andreport background.

Data sets are zip files of ESRI shapefiles or, where noted, jpg or tif image files, or the MrSID compression file for the LandSat data. Metadata for the layers are included with the downloads except where noted.
