Abstract

The Office of the Geographer and Global Issues at the U.S. Department of State produces the Large Scale International Boundaries (LSIB) dataset, currently at version 10.2 (published 28 May 2021).

Sources for these data include treaties, relevant maps, and data from boundary commissions and national mapping agencies. Where available, the dataset incorporates information from courts, tribunals, and international arbitrations. The research and recovery of the data involves analysis of satellite imagery and elevation data. Due to the limitations of source materials and processing techniques, most lines are within 100 meters of their true position on the ground.

Attributes -- The dataset uses the following attributes:
Country Code: Country-level codes are from the Geopolitical Entities, Names, and Codes Standard (GENC). The Q2 code denotes a line representing a boundary associated with an area not in GENC.
Country Names: Names approved by the U.S. Board on Geographic Names (BGN). Names for lines associated with a Q2 code are descriptive and are not necessarily BGN-approved.
Label: Required text label for the line segment where scale permits. 
Rank/Status: Rank 1: International Boundary, Rank 2: Other Line of International Separation, Rank 3: Special Line
Notes: Explanation of any applicable special circumstances.

Cartographic Usage -- Depiction of the LSIB requires a visual differentiation between the three categories of boundaries: International Boundaries (Rank 1), Other Lines of International Separation (Rank 2), and Special Lines (Rank 3). Rank 1 lines must be the most visually prominent. Rank 2 lines must be less visually prominent than Rank 1 lines. Rank 3 lines must be shown in a manner visually subordinate to Ranks 1 and 2. Where scale permits, Rank 2 and 3 lines must be labeled in accordance with the “Label” field. Data marked with a Rank 2 or 3 designation does not necessarily correspond to a disputed boundary. 

Additional cartographic information can be found in Guidance Bulletins published by the Office of the Geographer and Global Issues (https://hiu.state.gov/data/cartographic_guidance_bulletins/).

Purpose

The Office of the Geographer and Global Issues at the U.S. Department of State produces the Large Scale International Boundaries (LSIB) dataset. These data and their derivatives are the only international boundary lines approved for U.S. Government use. They reflect U.S. Government policy, and not necessarily de facto limits of control. This dataset is a National Geospatial Data Asset.

Supplemental Information

The lines in the LSIB dataset are the product of decades of collaboration between geographers at the Department of State and the National Geospatial-Intelligence Agency with contributions from the Central Intelligence Agency and the UK Defence Geographic Centre.

Changes from Prior Release

This version of the LSIB contains changes and accuracy refinements for the following line segments. These changes reflect improvements in spatial accuracy derived from newly available source materials, an ongoing review process, or the publication of new treaties or agreements. Changes to lines include:

· Armenia / Azerbaijan

· Cambodia / Vietnam

· Cameroon / Nigeria

· Congo (Brazzaville) / Congo (Kinshasa)

· France / Spain

· Greece / Turkey

· Guyana / Suriname

· Guyana / Venezuela

· Israel / Jordan

· Italy / Vatican City

· Kyrgyzstan / Tajikistan

· Lithuania / Russia

· Spain / United Kingdom (Gibraltar)

· Tajikistan / Uzbekistan

This release also contains topology fixes, land boundary terminus refinements, and tripoint adjustments.
