In Living Atlas there is a very useful UK feature layer provided by
ESRI called OS Open Boundary-Line, which gives county and electoral
boundary lines (wards, divisions, constituencies, etc). However the
Polling District boundaries (for Farnham at least) are out of date -
the border changed for the May 2023 local election, but the Polling
District layer is still showing the old Polling District Boundary. It
shows it going down Bear Lane for example, but it now goes down St
Cross Road (and has done since the May 2023 election). I realise this
information comes from the Electoral Services department, possibly via
the Office for National Statistics, and Ordnance Survey - but when
will it be updated?
