Sources included the National Atlas (http://nationalatlas.usgs.gov) and Mexico's Instituto Nacional de Estadística, Geografía, e Informatica (http://inegi.gob.mx). This dataset was developed by the U.S. Geological Survey's Border Environmental Health Initiative (http://borderhealth.cr.usgs.gov/index.html). International borders politically divide the landscape but rarely represent barriers for environmental issues. The major issues surrounding the U.S.-Mexico border involve economics and population growth that present challenges to environmental management and natural resource planning. To monitor trends and analyze the stresses to the environment, binationally integrated baseline datasets that portray the status of the landscape are needed. The primary objective of this project is to develop integrated, environmental resource and human health datasets for display and further analysis within a geographic information system (GIS) framework. Datasets created for the Border Environmental Health Initiative (BEHI) follow watershed boundaries as defined by Woodward and Durall (1996). As part of the U.S.-Mexico Border Field Coordinating Committee Issues Team, Woodward and Durall used surface-water drainage basins as the primary basis for defining and delineating the extent of the border area from a shared-water resources perspective. In order to provide integrated datasets in the border region, local and regional BEHI datasets have been clipped to this boundary.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DIV> <DT><I>Purpose:</I></DT> <PRE ID="original">This dataset was created to provide resource managers, public officials, researchers, and the general public with ready access to accurate, impartial, scientific information to strike a balance among human needs for resource utilization, environmental quality, and human health.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DIV> <DT><I>Supplemental_Information:</I></DT> <PRE ID="original">Additional information about the Border Environmental Health Initiative can be found at http://borderhealth.cr.usgs.gov and datasets are available for viewing through an Internet Mapping Service (follow links on the main page to the Internet Mapping Service Viewer).</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> </DL> </DD> <DT><I>Time_Period_of_Content:</I></DT> <DD> <DL> <DT><I>Time_Period_Information:</I></DT> <DD> <DL> <DT><I>Single_Date/Time:</I></DT> <DD> <DL> <DT><I>Calendar_Date:</I> 2/03/2006</DT> <DT><I>Time of Day:</I> unknown</DT> </DL> </DD> </DL> </DD> <DIV> <DT><I>Currentness_Reference:</I></DT> <PRE ID="original">ground condition</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> </DL> </DD> <DT><I>Status:</I></DT> <DD> <DL> <DT><I>Progress:</I> Complete</DT> <DT><I>Maintenance_and_Update_Frequency:</I> None planned</DT> </DL> </DD> <DT><I>Spatial_Domain:</I></DT> <DD> <DL> <DT><I>Bounding_Coordinates:</I></DT> <DD> <DL> <DT><I>West_Bounding_Coordinate:</I> -117.157257</DT> <DT><I>East_Bounding_Coordinate:</I> -96.828152</DT> <DT><I>North_Bounding_Coordinate:</I> 33.094984</DT> <DT><I>South_Bounding_Coordinate:</I> 25.853244</DT> </DL> </DD> </DL> </DD> <DT><I>Keywords:</I></DT> <DD> <DL> <DT><I>Theme:</I></DT> <DD> <DL> <DT><I>Theme_Keyword_Thesaurus:</I> Library of Congress</DT> <DT><I>Theme_Keyword:</I> Environmental Heath</DT> <DT><I>Theme_Keyword:</I> Water</DT> </DL> </DD> <DT><I>Theme:</I></DT> <DD> <DL> <DT><I>Theme_Keyword_Thesaurus:</I> ISO 19115 Topic Category</DT> <DT><I>Theme_Keyword:</I> imageryBaseMapsEarthCover</DT> <DT><I>Theme_Keyword:</I> Imagery and Base Maps</DT> </DL> </DD> <DT><I>Place:</I></DT> <DD> <DL> <DT><I>Place_Keyword:</I> Mexican-American Border Region</DT> <DT><I>Place_Keyword:</I> United States of America</DT> <DT><I>Place_Keyword:</I> Mexico</DT> <DT><I>Place_Keyword:</I> Rio Grande</DT> <DT><I>Place_Keyword:</I> Río Bravo</DT> </DL> </DD> </DL> </DD> <DT><I>Access_Constraints:</I> The data are available for viewing at http://borderhealth.cr.usgs.gov</DT> <DIV> <DT><I>Use_Constraints:</I></DT> <PRE ID="original">There is no guarantee concerning the accuracy of the data.
