Large Scale International Boundaries (LSIB)

Large Scale International Boundaries Version 10, Release Date: March 10, 2020.

The Office of the Geographer and Global Issues at the U.S. Department of State produces the Large Scale International Boundaries (LSIB) dataset. These lines and those generalized from this dataset are the only international boundary lines approved for use on U.S. Government maps, databases, and other geographic products such as annotated imagery. They reflect U.S. Government policy, and not necessarily de facto control. The lines are believed to be accurate to within 100 meters. Sources for these lines include treaties, relevant maps, and data from boundary commissions as well as national mapping agencies. The research and recovery of the lines involves analysis of satellite imagery and elevation data. Where available, the dataset incorporates information from courts, tribunals, and international arbitrations.

Attributes The dataset uses the following attributes: Attribute Name Explanation Country Code Country-level codes are from the Geopolitical Entities, Names, and Codes Standard (GENC). The UU code denotes a line representing the boundary of an area of unusual sovereignty. Country Names Names approved by the U.S. Board on Geographic Names Label Text label required for the line segment where scale permits Rank/Status Rank 1: International Boundary Rank 2: Other Line of International Separation Rank 3: Special Line Rank 4: Special, scale dependent line Usage: Ranks 2 and 3 must be shown in a manner visually subordinate to Rank 1 lines.
