It provides an electronic, spatially referenced representation of the international boundary that may be used for the purposes of displaying the boundary and to integrate binational datasets tied into the boundary line. This dataset was created to provide resource managers, public officials, researchers, and the general public with ready access to the location of the international boundary for use to develop binational datasets that depict various land use/land cover datasets including resource utilization, environmental quality, and human health. Credit for the completion of the international boundary line should be given to the International Boundary and Water Commission, United States and Mexico. Cooperating agencies include the National Institute of Geography and Statistics, Mexico, and the U.S. Geological Survey. underDevelopment Delbert Humberson International Boundary and Water Commission GIS Manager 915-832-4702 915-832-4167 4171 North Mesa, C-100 El Paso Texas 79902 USA Delbert.Humberson@ibwc.gov 08:00-16:30 pointOfContact notPlanned Library of Congress International Boundary IBWC Minute No. 1970 Boundary Treaty theme None US Mexico border region United States of America Mexico Colorado River Rio Grande River Rio Colorado Rio Bravo place None Governmental Units and Administrative and Statistical Boundaries Theme National Geospatial Data Asset NGDA theme NGDA Portfolio Themes 2010-02-01 revision http://www.fgdc.gov/initiatives/resources/2013-2-1-ngda-data-themes-fgdc-sc-revised.pdf The data are released on the condition that neither the USIBWC, its cooperators, nor the U.

Errors of unknown magnitude might have been introduced in areas where the determination of the location of the channel of the Rio Grande/Rio Bravo was difficult, for example, in dense salt cedar stands. Errors, as much as 5 meters, might have resulted from error present in digital orthophotos used to digitize the international boundary along the Colorado River. This representation of the international boundary between US and Mexico is a vector digital line compiled from three separate boundary sources. These sources include a shapefile boundary line for the Colorado River, a shapefile boundary line for the Rio Grande/Rio Bravo River and a shapefile of monument points for remaining areas of the border. The compiled line extends from the mouth of the Rio Grande River to the approximate coastline on the west edge of the US/Mexico border and into the Pacific Ocean. Monument points used to create the western portion of the boundary end just east of the actual coastline, therefore, the line was extended in ESRI ArcGIS software to the approximate edge of the coastline from the westernmost monument point and into the Pacific Ocean based on the IBWC published International Maritime Boundary map of December 12, 1970. The line feature class was visually examined for disconnected portions. The individual line shapefiles were snapped together using GIS software and visually examined to ensure there were no gaps. The line shapefile was compared to orthoimagery as a visual check for consistency. Combined border: All source shapefiles were converted to Geographic coordinate system, NAD83. Monument points in shapefile format were separated into two shapefiles using ArcToolBox Select tool, one shapefile for points west of the Colorado River, and the other for points east of the Colorado River. The individual points were connected within each shapefile and converted into line geodatabase feature classes using Safe Software FME Point Connector transformer. All portions of the boundary line were combined using FME Aggregator transformer. The combined line was then processed through the FME Snapper transformer, using a snapping tolerance of 0.02 decimal degrees. This connected the geometry of the line portions and closed the gaps between them. The boundary line on the west coast ends approximately 150 meters east of the coastline at the westernmost monument point. The line was extended to the approximate coastline and into the Pacific Ocean using ArcGIS. The completed boundary feature class was converted to ESRI shapefile format using FME. Attribute fields derived from the USGS National Boundaries Dataset were retained. 2011-02-01T00:00:00 Laurie Temple U.S. Geological Survey, National Geospatial Technical Operations Center Cartographer 303-202-4485 303-202-4504 PO Box 25046, MS 510, DFC Denver Colorado 80225 USA ldtemple@usgs.gov processor Metadata imported. 2010-08-23T17:13:59 Metadata imported. 2011-02-10T12:09:41 Source Contribution: Surveyed monument points were joined to create the international boundary from the west coast of North America to the Rio Grande River portion of the boundary, excluding the Colorado River area of the international boundary.
