However, reading the previous statement [1] and yesterday's letters from
the Secretary of State [2], it should be possible to create boundaries
in OSM for the new authorities based on existing open data. The areas
will comprise either:
- a combination of existing Councils
- existing Councils plus/minus some parishes from neighbouring
authorities (The proposal from Leicester to spilt some parishes was
rejected)
- existing Councils plus/minus some electoral wards from neighbouring
authorities
Yes; the new authorities will almost certainly all be based on existing
electoral geography. Doing it otherwise would require a full review by
the Local Government Boundaries Commission for England, and there simply
isn't time for that. The granularity will be different - some new
authorities will be based on a simple aggregation of existing districts,
while others will go down to parish and ward/division level. But the
building blocks will all still be there.
So it will be possible to construct boundaries for the new authorities
based on the descriptions which will be given in the relevant Structural
Changes Orders when they are published. Some of these will be simpler
than others, but a definitive dataset will always be possible.
AFAIK Parish boundaries are all on OSM already, so the first two seem
plausible to create if you can find a list of the parishes affected.
The third scenario will be more difficult because very few electoral
wards are on OSM and many of those are out-of-date too.
Electoral wards are in OS Boundary-Line, which is OGL. So even if it's
not currently in OSM, the necessary underlying data is readily available.
