Re: [Talk-GB] 'C' class roads references.
I don't understand the logic of doing this?
Surely we map for what is there on the ground, not how it renders? If a road
has a reference number or a name, surely it is up to the render if it should
show that information or not, not how we tag it in the database?
In my particular area I have people "helicopting in" to remove the C and U
numbers off the roads, just because they don't like the way it renders! But
the fact is that none of the rural roads have signs giving the name, so just
because my local council can't agree on putting up signs on the road I live
on, it shouldn't have a name on OSM?
Again in my area this is the reason OpenStreetMap is gaining a lot of ground
compared to other maps, because it shows the road names and reference numbers
which are useful for locals and people trying to find their way around. For
example, the local media will give a list of road names and reference numbers
during times of flood to indicate what roads locals should avoid. There are
no other comparable maps which show this information, only OSM and a lot of
people now use OSM because of that.
Just because a local authority doesn't signpost something, does not mean it
doesn't exist or isn't useful to local people.
Just my two cents on the this, and I would very strongly object to this being
carried out in County Fermanagh.

[Talk-GB] 'C' class roads references.
Hi
After many discussions over the years about the referencing of 'C' class
roads there appeared to be a general consensus to keep them in the
database but provide a unique tag to allow them not to be rendered.
This is a list of the discussions (there maybe others):
https://lists.openstreetmap.org/pipermail/talk-gb/2011-May/011632.html
https://lists.openstreetmap.org/pipermail/talk-gb/2013-March/014555.html
https://lists.openstreetmap.org/pipermail/talk-gb/2013-April/014788.html
https://lists.openstreetmap.org/pipermail/talk-gb/2014-August/016392.html

https://lists.openstreetmap.org/pipermail/talk-gb/2015-May/017414.html
However this task was never undertaken. I decided to grab the bull by
the horns.
I used variations of this Overpass query within JOSM to find the
numerous 'C' refs keys (listed below) tagged to the different road
classification.
I uploaded in batches split by geography &/or tag values to make it
easier for me to verify
I used detailed changeset descriptions to make it easier to rectify if
needed. If you spot any errors please let me know.
[maxsize:2073741824];
area(id:3600058447,3600058437,3600058446); // England, Wales, Scotland
//[bbox:{{bbox}}];
way[highway=*highway classification"][~ref~"^C[0-9]{1,4}$"] (area);
//out tags;

*Various keys used for 'C' refs:
(listed most popular down)
* ref

admin:ref

I've amended them to *'highway_authority_ref*'. It was discussed in the
May '15 thread where it was felt official_ref or admin_ref wasn't
specific enough. Feel free to discuss here if you have strong objections
to it. If there's a consensus to change it's quite easy now they're all
under a single tag.
Note I didn't include Northern Ireland as I'm unsure whether they're
signed on the ground or not. Is anyone able to verify?
These are the trunk, primary & secondary roads which previously either
had a ref or highway_authority_ref:
http://overpass-turbo.eu/s/AM7
Similarly these are the pedestrian, service, residential & track
http://overpass-turbo.eu/s/AM8
These still have 'ref' tags: proposed, abandoned, construction, path,
footway & cycleway; possibly copy paste errors or should be prow_ref?:
http://overpass-turbo.eu/s/AMc
Please amend if you have local knowledge & believe any of the above are
an error.
Cheers

[Talk-GB] Open Data 6: Aberdeen, 3 Nov 2018
The 6th UK Open Data Camp is being held in Aberdeen on Saturday 3 November. If you attend, you will meet other OSM UKers, hear about government open data like LIDAR and the Environment Agency, discuss the pros and cons of open data, etc. It is an unconference all about open data, 'unconference' meaning that it does not follow a traditional conference structure: there are no pre-booked speakers; a large number of people pitch sessions on the day and get allocated rooms and timeslots; many sessions are impromptu "i'm interested in subject , come along and we will discuss it"; not everyone has to speak but there is plenty of opportunity to do so in a friendly environment. Myself and a few other OSM UKers have attended previous episodes and found them very interesting. Tickets are free. But they go fast. First ticket release is in just over an hour's time https://www.eventbrite.co.uk/e/open-data-camp-6-aberdeen-tickets-48364030116 then a list of other dates/times on that page. See you there?
