2nd pedestrian crossing was actually at Cedar Hills and an entrance into a mall; Jenkins already has crossing marked.

A benchmark appears to be regarding elevation (vertical!), and often in the side of a pillar (though I *think* I've seen them in the side of a wall/building):

With a pillar being used for horizontal positioning?
Although I just tagged the broad hill one with survey_point=triangulation, it may well have a "benchmark", and key=value1;value2 doesn't work well, so maybe man_made=survey_point+triangulation_pillar=yes+benchmark=yes? Possibly a tagging list discussion is warranted; I've not looked on taginfo too much either.

Just looking at trig points and wondering if the man_made=survey_point is specifically a survey_point=triangulation.

I've not surveyed stops for some time, so it's interesting that these longer refs have started appearing. Did you notice the ref on the 'flag' (sign with the common bus numbers and short name?). I'm aware of NaPTAN. Maybe we should aim for various refs so this can start to make more sense (long/short/naptan/atco/local).

Where did you get the longer one from, though? Certainly if bus stops just have the 'flag' part, with or without a shelter, and no time-table, is the longer ref actually openly obtainable?

Great to have these not be bus-stations any more :) Just a little query: the refs seem much longer than that I've put on a lot of other bus stops, where I've taken the one off the sign or the (bottom right of?) the timetable.

As far as I can tell, this does have a wall around it, so am adding this back in. Please comment if you believe this is inaccurate.

I've gone with waste=dog_excrement to make things a little more clear, as it's likely just to be for bags of...that... to go in! Also, reading it literally, it makes me think of bins to throw waste dogs into ;)

Are the waste baskets here more accurately waste=dog_excrement ?

Please see my comment on another of your changesets regarding this.

For tagging of CCTV, please consider tags such as listed here: osm.wiki/Tag:man_made%3Dsurveillance
For example, with
man_made=surveillance
surveillance=public
surveillance:type=camera
Please ask if you need more help; I could retag but I don't know exactly what was there :)

Thanks for the additions.
In future it would be useful if you could split your edits into smaller chunks, with more descriptive text for what you've changed (and why). This makes it easier to see what has changed later.
For example, I can see you added some roads near the high-rise buildings to the north, but also around the pub and housing office.
If you accidentally delete an object, please undo that change before saving, rather than recreating the object. I'm not sure if that's what's happened with the Shopping centre.
I look forward to working with you :)

What's the source of the peak data?

Please explain how there is not a wall around here?
