OpenStreetMap: A Global Guide to Administrative Boundaries for Every Country
OpenStreetMap: Admin_level for All Countries
I have compiled a comprehensive reference for mapping administrative boundaries across the globe using OpenStreetMap. This guide details the specific admin_level tags required for countries ranging from Afghanistan to Cameroon, ensuring accurate data representation for provinces, districts, and municipalities. By standardizing these tags, we can improve the consistency and utility of geographic data for users and developers worldwide.
Use name=* to indicate the name of the commune, and ref:ONS=* to indicate the unique identifier given by ONS.
