[Talk-GB] How to Fix a "Fix-Me"

Hi Peter,

These very much look like fixmes which got forgotten. They do not show up
directly in many editors (and only recently in iD). In this case all the
ones you mention look to have been fully resolved by the existing mapping.
In that case it's safe just to remove the fixmes, which is good because it
stops others thinking this area needs a visit.

Obviously not every case is likely to be so clear cut. I suspect many of us
leave fixme tags if we are not absolutely sure that they have been
resolved: a false positive signal is better than a false negative one.
However, with more in-editor QA we may need to be more pro-active in
checking for fixmes which are no longer relevant.

It's always a good policy if unsure to start a discussion on the changeset
where the fixme tags were created. Often fixme tags are somewhat terse. A
direct question to the original author may elicit which information they
really felt they were lacking at the time. For instance in a case like this
I presume aerial imagery with the new roads was not available, or that it
only showed the area during construction. If someone walked or cycled
through to get GPS tracks they may not have been able to survey many of the
nuances of the site.

Personally I try and add multiple source tags to give an idea of what
information I used. For instance I have recently been adding footpaths
which I have seen leading of country roads in Yorkshire & Denbighshire. I
know where the path starts, what type of PRoW the path is and roughly where
it heads. Additional information I cull from old out-of-copyright maps &
aerial images, so the actual true alignment of the path is always an
approximation. If someone walks the path, GPS traces become available etc,
then the fixme can be removed & the source:geometry tag updated.
