Package 'mapSenegal'

Title: Administrative Boundaries of Senegal
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.
