Sierra Leone administrative level 0-4 edge-matched gazetteer, shapefiles, geodatabase, and geoservice. This dataset was updated in January 2024 to correspond to the COD-AB with the newer five-regions administrative structure. COD-EM datasets do not replace the authoritative [COD-AB available here](https://data.humdata.org/dataset/cod-ab-sle); however COD-EM datasets may be preferred for cartographic purposes. See caveats. These layers are suitable for database or GIS linkage to the [Sierra Leone - Subnational Population Statistics](https://data.humdata.org/dataset/cod-ps-sle) tables. Vetting and live service provision by Information Technology Outreach Services (ITOS) with funding from USAID.
