| Title: | Administrative Boundaries of Senegal |
| Version: | 0.1.1 |
| Description: | The administrative boundaries of Senegal are provided at several levels, including regions, departments, arrondissements and communes. The Global Administrative Areas database, or 'GADM' https://gadm.org/, is the primary source for these layers. The dataset is complemented by the incorporation of additional geographic layers, such as localities, universities, roads, or health facility locations. |
