Heya, thanks for adding houses and other detail around Natland, it’s nice to see the map becoming more complete round here.

One thing — the aerial imagery around Natland is offset from ground truth by about -0.97,-1.04 metres, so please adjust the imagery before starting to edit. You can do this with the ‘Imagery Offset’ settings under ‘Background Settings’ on the right.

The aim is to align the aerial imagery to the OSMUK Cadastral Parcels overlay. This is needed because aerial imagery is only very roughly aligned by the supplier, and its relative alignment changes every time it’s updated, and changes across the country. Some places are several metres out of alignment compared to ground truth. So when editing map geometry it’s important to align the imagery before starting.

There’s more information about this on the wiki (osm.wiki/Good_practice#Align_aerial_imagery_before_tracing) but I’m also happy to answer questions if you have any

Happy editing :)

Hi, I’ve re-added this bridge in changeset/159127095 and used a lifecycle prefix (osm.wiki/Lifecycle_prefix#Stages_of_decay) to mark it as missing, so that people editing the area in future can get some context about why the footpath seemingly randomly has a gap in it.

If I’m misinterpreted what you mean by ‘missing’ please say. It’s quite hard to tell from such a brief changeset comment. Please consider providing a little more information in your changeset comments in future, so other editors on this collaborative project can follow along. In particular, listing your sources makes it easier for edits to be checked. See osm.wiki/Good_changeset_comments

Thanks.

Have you surveyed the speed limits here now? What’s the source of your information?

For anyone reading this in future, this is a follow-up to changeset/159067050

5mph seems a bit unlikely for the whole of Mears Beck Close. Have you surveyed this?

I’ve just messaged Roshmaps about it, thank you for the reminder.

What are you trying to achieve with these speed limits edits? Are you trying to make sure that every highway in the network has a speed limit set, even if that means guessing them? I’m interested in understanding your motivations here. It might help us see more eye-to-eye.

Hiya, did you mean to change way/219044962 to access=permissive? That would indicate that the default access for that track is permissive, but the tracks either side of it are marked as access=private.

access=private is the norm for farm tracks

Thanks in advance :)

Are you sure the roads in Ripley St Thomas (e.g. way/433800865) have a 10mph speed limit? I agree there’s a campus-wide speed limit of 10mph on the RLI campus, but Ripley St Thomas is separate.

What’s your source for this information?

Can you please stop adding speed limits to private driveways? It’s not correct.

For anyone looking at this later, this isn’t just an arbitrary deletion of a barn, it’s resolving a merge conflict. See changeset/158898865

Also add some missing service roads/building passages along Stramongate, and roughly adjust the terraced building shape to accommodate them. This terrace needs a lot more work, but I don’t plan on doing that now.

Good point, done in changeset/158813895 ta

Ah, indeed, in this case whoever mapped this has split the driveway at the property boundary, so this edit makes sense.

But more generally, what about the other private driveways you’ve put a speed limit on?

158521457 about 1 year ago

Hiya. Are you sure it’s valid to set a speed limit on someone’s private driveway? As I understand it, speed limits apply to public roads. None of these driveways have a speed limit signed on the ground.

I think perhaps you are being misled by the title which the ID editor applies to crossing=traffic_signals nodes. It does title them as “Crossing With Pedestrian Signals”, but if you look lower down, the Type is “Crossing With Traffic Signals”. I think it’s a bug for ID to title them “Crossing With Pedestrian Signals”.

In any case, the wiki gives the canonical meaning of the tags, not whatever labels ID applies to them. See crossing=traffic_signals

As I have said previously, the wiki documents bicycle=dismount as meaning that no cycling is allowed, but you are allowed to push your bike. See bicycle=dismount

So bicycle=dismount is legally correct here, and more appropriate than bicycle=no because of the “cyclists dismount“ signs. IMO these are an acknowledgement from the council that cycling is not legal for a short stretch here, but that people will want to do it because there are cycle paths at both ends of the dismount stretch.

The wiki documents crossing=traffic_signals as “This tag is used for traffic light controlled pedestrian crossings.”, i.e. the lights are for the traffic, not the pedestrians. That describes what’s here on the ground. Pedestrians cross when the lights are red, and vehicles won’t stop otherwise. IIRC there isn’t a button for pedestrians to request to cross, and that can be represented using button_operated=no. I didn’t add that tagging because I haven’t explicitly resurveyed it to check that.

Could you please stop removing geometric detail from the map? If you think these shouldn’t be crossings, then maybe change them to footway=link, but don’t delete correct geometric detail which others have added to the map.

OK, fair enough. Thanks for the explanation
