Hill data from the Database of British & Irish Hills v18.3 (CC BY 4.0); boundary from DataMapWales (Open Government Licence) — contains Natural Resources Wales information © Natural Resources Wales and database right, contains Ordnance Survey data © Crown copyright and database right. Hills are assigned by summit position against a generalised boundary, so a top within roughly 100 m of the edge can fall on the wrong side.
