Administrative boundary CODs include:
Geographic boundaries in shapefile, geodatabase, and other formats, often including live geoservices. Some countries also have edge-matched administrative boundary variants. (See COD-AB-EM.)
COD-AB datasets can be linked by database or GIS to COD-PS datasets, when available using the P-codes as a key.
Boundaries and gazetteers reflect the country’s specific administrative hierarchy.
COD-AB datasets are adopted by the country or regional Information Management Working Group as the standard.
