Global Subnational River Borders

<p>This dataset presents Global Subnational River-Borders (GSRB), a first global&nbsp;geospatial dataset of subnational, as well as national, political borders set by large rivers. GSRB incorporates three previous vector datasets (GAUL, GRWL + +, and WDBII) to map and quantify the use of large rivers as political borders at local (Level 2), state (Level 1), and national (Level 0) scales.</p> <p>When&nbsp;referencing this dataset, please use the full paper citation:</p> <p>Sarah J.
