Description:

Abstract:

This binationally integrated counties and municipios dataset was developed by the U.S. Geological Survey’s (USGS) Border Environmental Health Initiative (<http://borderhealth.cr.usgs.gov/index.html>) using a common international boundary and counties and municipios data from the National Atlas of the United States and the Instituto Nacional de Estadística, Geografía, e Informática (INEGI).

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.

Purpose:

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.

Supplemental_Information:

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).

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

County and municipio names and FIPS codes were not changed from the original datasets and their accuracy reflects the accuracy present in the original datasets.

Logical_Consistency_Report:

The international boundary, used for integration of the counties and municipios in this dataset, was created by the USGS U.S.-Mexico Border Health Initiative for data integration purposes only and should not be considered an official boundary. Otherwise, the data reflect boundaries and topological relationships present in the source data and include any errors present in the source data.

Completeness_Report:

At the time of integration, this dataset included all counties and municipios in the 10 border states of the U.S.-Mexico Border Region.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The horizontal accuracy of the county and municipio boundaries is dependent on the horizontal accuracy of the source data. U.S. county boundaries derive from the National Atlas, while Mexican municipio boundaries are from INEGI. The only exceptions are the parts of the county and municipio boundaries that follow the Rio Grande. These boundaries were digitized from the 2004 National Agricultural Imagery Program (NAIP) orthoimagery. The horizontal accuracy of the NAIP along the Rio Grande determines the horizontal accuracy of the county and municipio boundaries along the Rio Grande.
