The passage of the North American Trade Agreement (NAFTA),establishment of the Border Environmental Cooperation Commissionas well as the EPA U.S./Mexico Border XXI Program has focusedattention to the environmental social-cultural, and economicconditions in the United States-Mexico frontier and to theenhanced necessity of a binational, transborder approach inaddressing problems. Towards this end, this U.S.-Mexicoborderlands Thematic Mapper selection is designed to be utilizedas fundamental part of a basic geographic information systemdatabase for natural resource, environmental, and land-managementstudies.

A paper copy of the Geologic Map of the Catalina Core Complexand San Pedro Trough (Dickinson, 1992) was scanned anddigitized by U.S. Geological Survey staff and contractors atthe Southwest Field Office (Tucson, AZ) in 2000-2001 for inputinto an ArcInfo geographic information system (GIS). Theresulting geologic map database (in ArcInfo format) can bequeried in many ways to produce a variety of geologic maps.Digital base map data files. (topography, roadways, towns, andhydrography) are not included: they may be obtained from avariety of commercial and government sources. Geologic mapgraphics and plot files that are provided in the Open-FileReport are representations of the digital database and are notdesigned to be...

A spatial database was created for the Drewes (1980) tectonic map of southeast Arizona: this database supercedes Drewes and others (2001, ver. 1.0). The west tectonic map (Drewes, 1980) was converted to digital format by Optronics Specialty Co., Inc. and published in 2001. Staff and a contractor at the U.S. Geological Survey in Tucson, Arizona developed a digital geologic map database for the east map in 2001, made revisions to the previously released digital data for the west map (Drewes and others, 2001, ver. 1.0), merged data files for the east and west sheets, and added additional data not previously captured.
