Haxel 2005 Preliminary integrated databases for the United States - Western States: California, Nevada, Arizona, and Washington Version 1.0 vector digital data U.S. Geological Survey Open-File Report OFR 2005-1305 Reston, Virginia, USA U.S. Geological Survey Original source of this data was the Arizona Geological Survey. pubs.usgs.gov/of/2005/1305 These digital maps are a reformulation of previously published maps, primarily maps of states. The reformulation gives all the maps the same structure and format, allowing them to be combined into regional maps. The associated data tables have information about age and lithology of the map units, also in a standard format. Provide digital maps and databases that, because of their common structure and format, allow creation of regional maps that depict age and lithology of map units.
The data is provided in decimal degrees and in Lambert Conformal Conic projection. The data is provided in both coverage and shapefile format, and includes supplemental attribute tables. No attempt was made to reconcile differences in mapping across state boundaries. 2005 publication date Complete None planned -115.692550 -108.394050 37.506613 30.723759 none geology lithology geologic age maps none USA Arizona No warranty, expressed or implied, is made regarding the accuracy or utility of this data for general or scientific purposes, nor shall the act of distribution constitute any such warranty.
