I suspect this is one that must have been tried before, so i'm interested if there's history.

But it seems we have a gap around political boundaries. For instance I've been trying to query overpass turbo for nodes within my ward. But it appears that data is only partially present across the UK

I'd suspect this data should be easy to obtain and license.

I think it's important because it would allow users to connect ground truth features in an area to political representatives that might be able to change them. Perhaps a lack of amenities in one ward could be connected to a representative who could then be asked to take action within local government?

I'm particularly interested in wards, but would suggest a candidate list could be something like this:

• Local government 'electoral division' (wards for parish / district councils, electoral division for county councils) boundaries

• Directly elected mayors - Boundaries here are likely to be more complicated, in some cases I suspect it maps to the administrative borders of a local authoirty, in other cases it may unite a few (eg London boroughs?)

• Perhaps police and crime commisioners for Englad and Wales (they map to the 41 police force areas, not sure if there are already administrative boundaries?)

• Devolved government constituency boundaries (NI Stormont, Senedd, Scottish Parliament?)

• Parlimentary constituencies - Not sure if these are already mapped?

After that I somewhat lose track of other forms of democracy, city of london has some unusual mechanisms, and there's some older stuff like aldermen and honorific roles i'm even less sure about.

Apologies if i'm re-tredding preivously considered territory here. Happy to take a previous discsusion to go read up on?

I agree that it would be nice to have political boundaries in OSM. It is a huge pain though to continuously maintain the validity of those boundaries and easy to break boundaries while editing features which are tied to the boundary. I have myself fixed the French and Spanish constitutional admin districts a few years ago and it is a very manual labour. Happy to participate looking at UK admin boundaries.

I'm going to suggest waterways/courses.

I've been doing some mapping in Wales (family nearby) and it highlights to me how much stuff traced from NPE is still there. Waterways change a lot.

There's opendata streetview layer which is very useful for this. The latest Bing imagery is, on the whole, very well aligned when compared to multiple gps traces and streetview layer.

The clarity available is allowing many bridges/culverts and redirected waterways be picked up.

Progress on this might be tricky to quantify though.
