Source project UKN002: Wester Hermiston, Edinburgh; South of M8 Claylands-Hermiston, Edinburgh. Wester Hermiston source locality represented by Hermiston settlement near Edinburgh; approximate locality only. Locality representative point only; no site coordinate inferred.
Map points are not surveyed parcel boundaries or electricity connection nodes. The stage is a source-based interpretation at the evidence cutoff, not a current-status check.
