Description: This provisional international boundary was developed by the International Boundary and Water Commission-United States and Mexico (IBWC), to be used as a common boundary for the clipping and geometric integration of binational geospatial data sets and represents the international boundary as agreed upon by the Governments of the United States and Mexico in accordance with the 1970 Boundary Treaty. 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 datsets tied into the boundary line.
