District boundaries around here seem a little odd - along a good chunk of the Thames they seem to run slightly inland of the river bank, rather than either aligned with the bank or the middle of the stream, either of which would seem to make a bit more sense.

Is this just an artefact of two data sources having slightly different ideas of where the river is, or is it intentional?

This site was sold off for housing development by the MOD a few years ago, though the development itself seems stalled waiting for planning permission. MOD have built a new Army Cadet building in one corner of the site - see eg/ http://www.glrfca.org/managing-the-estate/projects.html - but otherwise no longer use the site.

As such, not sure if we should remove the "TA Centre" area, or leave it in place pending new building work

Two newbuild apartment blocks here ("Aqua"); not on aerial imagery. Construction currently finishing up.

Should the boundary here follow the river? It looks vaguely like it should (same sort of pattern) but no way for me to practically check.

There is a connecting footpath through this area east to west - signposted, and shown on other maps, but not clear on the ground quite where it actually is.

What is this strange line? A railway? Hard to tell from the aerial imagery
