The Border Environmental Health Initiative Study Area dataset follows watershed boundaries defined by Woodward and Durall (1996). As part of the U.S.-Mexico Border Field Coordinating Committee (FCC) 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. This dataset contains the study area boundary with 8 subareas described by Woodard and Durall. Boundaries in the United States were extracted from the 8-digit Hydrologic Unit Codes (HUCs) from the National Atlas (&lt;http://nationalatlas.usgs.gov&gt;). Boundaries within Mexico were derived from cuenca (watershed) boundaries from the Instituto Nacional de Estadística, Geografía, e Informatica (INEGI, &lt;http://inegi.gob.mx&gt;) Datos Vectoriales de la Carta Topografica a escala 1:250k along the border. In order to provide integrated datasets in the border region, other local and regional BEHI datasets have been clipped to this boundary. 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.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DIV> <DT><I>Purpose:</I></DT> <PRE ID="original">This dataset provides a binational study area boundary based on watersheds and 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 BEHI 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>Multiple_Dates/Times:</I></DT> <DD> <DL> <DT><I>Single_Date/Time:</I></DT> <DD> <DL> <DT><I>Calendar_Date:</I> unknown</DT> </DL> </DD> </DL> </DD> </DL> </DD> <DIV> <DT><I>Currentness_Reference:</I></DT> <PRE ID="original">publication date</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> -117.424505</DT> <DT><I>East_Bounding_Coordinate:</I> -96.289287</DT> <DT><I>North_Bounding_Coordinate:</I> 34.565055</DT> <DT><I>South_Bounding_Coordinate:</I> 25.391430</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> Mexican-American Border Region</DT> <DT><I>Theme_Keyword:</I> Environmental Health</DT> <DT><I>Theme_Keyword:</I> Rio Grande</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> </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">For reference only.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DT><I>Point_of_Contact:</I></DT> <DD> <DL> <DT><I>Contact_Information:</I></DT> <DD> <DL> <DT><I>Contact_Organization_Primary:</I></DT> <DD> <DL> <DT><I>Contact_Organization:</I> US Geological Survey</DT> <DT><I>Contact_Person:</I> Public Information Officer</DT> </DL> </DD> <DT><I>Contact_Address:</I></DT> <DD> <DL> <DT><I>Address_Type:</I> mailing and physical address</DT> <DIV> <DT><I>Address:</I></DT> <PRE ID="original">8027 Exchange Drive</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DT><I>City:</I> Austin</DT> <DT><I>State_or_Province:</I> Texas</DT> <DT><I>Postal_Code:</I> 78754</DT> <DT><I>Country:</I> USA</DT> </DL> </DD> <DT><I>Contact_Voice_Telephone:</I> 512-927-3500</DT> <DT><I>Contact_Facsimile_Telephone:</I> 512-927-3590</DT> <DT><I>Contact_Electronic_Mail_Address:</I> gs-w-txpublic-info@usgs.gov</DT> </DL> </DD> </DL> </DD> <DIV> <DT><I>Data_Set_Credit:</I></DT> <PRE ID="original">Acknowledgment of the Border Environmental Health Initiative and (or) the U.S. Geological Survey would be appreciated in products derived from these data.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DT><I>Native_Data_Set_Environment:</I></DT> <DD>Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.1.1332</DD> </DL> </DD> </DL> <A HREF="#Top">Back to Top</A> <A name="Data_Quality_Information"><HR /></A> <DL> <DT><I>Data_Quality_Information:</I></DT> <DD> <DL> <DIV> <DT><I>Logical_Consistency_Report:</I></DT> <PRE ID="original">Topology tests were run to ensure that there were no gaps, dangles, or open polygons within the subarea dataset.
