Title
OCHA Global Subnational Administrative Boundaries
Description
Global administrative level 0-4 boundaries (COD-AB) dataset for 110 countries / territories, latest versions. This is an aggregation of [subnational administrative boundaries](https://data.humdata.org/dataset/?dataseries_name=COD+-+Subnational+Administrative+Boundaries&cod_level=cod-enhanced) available in 3 variations: **Edge-Matched**: Subnational boundaries are aligned to fit UN Geodata 1:1M international boundaries. This process results in simplification at the international border, but gaps and overlaps are eliminated. The internal resolution of each subnational boundary layer is not modified by this process. Recommended to use for most use cases. **Original**: Subnational boundaries are unmodified from their original source. There will be gaps and overlaps at the international border. Recomended if maintaining the integrity of the initial source is important. **Extended**: A specialty output to help those performing their own edge-matching when not using UN Geodata 1:1M international boundaries. Metadata about sources used is also available as a table. A version of this dataset is also available with [historic boundaries](https://data.humdata.org/dataset/cod-ab-global-historic).
