[Talk-GB] Fwd: Source of extra street imagery

[Rob Nickerson]

-- Forwarded message -
From:Rob Nickerson (OSMUK)


All,

Comma.ai was suggested at our OSM UK annual gathering as a potential source
of more street level imagery. They have hardware, some of which taps
directly in to the cameras already being installed in some cars.

A quick check on GitHub suggests that this might be a goer. Anyone
interested?

[Talk-gb-westmidlands] July Meetup

[Brian Prangle]

Hi everyone
This month we revert to our Trursday setup which is this week July 4th. As
part of our summer wanderings this month we're in Bromsgrove. Haven't had
time to select a pub yet so if anyone knows a good pub with decent food get
in touch. When we know where we're meeting I'll let you know but we'll meet
at 8 after the usual early evening mapping

Regards

Brian

Re: [Talk-GB] Importing NaPTAN Data

[Silent Spike]

Hey Tony,

Glad to hear I'm not the only person interested in using this data!

Wasn't aware of the conflation plugin, will have to give it a look now.
Always interested in collaboration, sounds like you've come to the same
conclusion as myself regarding getting import authorisation.

Cheers

Re: [Talk-GB] Importing NaPTAN Data

[Silent Spike]

Thanks for sharing your insight and expertise Stuart.

I can see why there might be resistance to importing data. Personally, I
take the view that it saves a lot of time even if it's not perfect
(progress being incremental and all). The majority of bus stops near me in
OSM were added by myself and that's taken a long time. If the data had been
imported already then it would be much quicker to see where stops are and
then simply verify/update the data that's there. With that in mind, that's
basically all I'm proposing - a set of human reviewed mechanical edits
specifically for the Aberdeen area as I'm familiar with it. Looking at the
data already I can see that most of it matches up with bus stops I've
mapped and some are a couple of meters off the true position.

To more accurately define the scope of what I'd like to do:

   1. Import data specifically for the Aberdeen admin area (ATCO code 639)
   2. Import stops of type BCT ("On-street Bus / Coach / Trolley Stop.")
   3. Import BCT stops of type MKD ("Marked (pole, shelter etc)")
   4. Manually conflate and review the data before upload
   5. Split the edits up according to the "LocalityName" data field
   (basically districts from what I can tell)

If I'm able to make it through that process then a methodology will have
been established which perhaps others can use for their areas too. Then
perhaps I can investigate other types of stop (hail and ride, custom,
flexible) and transport.

As for `naptan:` tagging (
https://wiki.openstreetmap.org/wiki/NaPTAN/Tag_mappings), I guess I'm just
not sure why much of that data has to be present in OSM. Surely just the
identifier is enough as it provides a link to the NaPTAN data itself.

Re: [Talk-GB] Importing NaPTAN Data

[Tony Shield]

Hi Spike

I'm interested in importing my local area - Chorley, Lancashire.

I've filtered the Naptan file to get Chorley csv file. I've then 
imported into JOSM conflation plug-in. I'm starting to understand how 
the conflation tool functions and I think the results are good. I've 
done several dry runs to get the technique correct. I'm planning to 
manually review each bus stop - not too bad when there are 3-400.


I too am trying to realise what Naptan codes and fields need to be 
populated for each bus stop, and agree with following the PTv2 scheme.


I haven't performed the import as I haven't been through the import 
authorisation process, and as Naptan is an established data import I 
think that it will not be too difficult as long as the process is correct.


Happy to work with you if you wish.

Regards

TonyS999

[Talk-GB] National Trust talk - leaflet

[Nick Allen]

Hi,

Many thanks to the team from OSMUK who set up the talks at the recent
AGM - I thoroughly enjoyed them & hope to contribute more on the
subjects.

I have one slight problem - I've lost my copy of the National Trust
handout of tags, and am hopeful that some kind soul will scan their
copy and send it to me.

Thanks in anticipation

Nick

Re: [Talk-GB] Polygon Coverage of Cornwall

[SK53]

Hi Emma,

A quick look suggests lots of landuse//landcover has not been mapped in
Cornwall, which is fairly typical of OpenStreetMap in general.

Given that you are using OpenMapTiles adding additional features to OSM is
probably the quickest way to get things which you are interested in
available in the tiles. This may not be too arduous if you are able to
assume that blank areas default to farmland.

If you use OSM data direct (e.g., from Geofabrik and loaded it into PostGIS
with osm2pgsql) or via geojson output from Overpass-Turbo and pull it into
a GIS package you could infill the gaps with something like CORINE data.
Obviously this is a long way from usable vector tiles, but probably gives
you decent complete coverage more quickly. There are some helpful
tabulations of how CORINE
and Urban
Atlas  data
codes correspond to OSM tags on the wiki. I may also have additional
residential/urban area polygons calculated from OSM which cover areas where
there are no landuse=residential polygons.

HTH,

Jerry

Re: [Talk-GB] Importing NaPTAN Data

[Stuart Reynolds]

Hi Spike,

There are two aspects to your question. The first is around mechanical edits 
(i.e. importing NaPTAN), and I’ll defer to the group for that because while I 
would like to use NaPTAN (matained, mostly) to update OSM (not maintained, 
mostly) across the UK, there is resistance to that - and it is because of that 
“mostly” issue, because in some areas bus stops have been more accurately 
surveyed.

However, one of my many hats (as a consultant) is as the DfT’s “Public 
Transport Data Standards” expert (Transport is a devolved power, but the 
Scottish Parliament usually keeps Scotland broadly aligned with England). If 
you want to know specific things about NaPTAN fields, then I can tell you what 
they are for and why we need them - either email me direct, or reply here if 
you think that it would be more widely interesting. That is particularly true 
of stop points which are “Custom & Practice” or “Hail & Ride” which are not 
marked on the ground at all (so are perhaps irrelevant from a mapping 
perspective), but are nevertheless valid stopping points (and very important 
from a PT perspective)

As a general note to both you and the wider community, the (English) Bus 
Services Act 2017 provides powers to compel Local Authorities to maintain 
NaPTAN data, and there are steps being discussed to assist in bulk 
“improvements” to the stop data ahead of the timetable provision which is 
intended to commence Jan 2020, mandatory by Jan 2021 (these dates all in the 
public domain, by the way). There is a similar Bill going through Holyrood at 
present, but I don’t know precisely what powers it will contain or what dates 
it will mandate.

Hello all

I'm using OpenMapTiles for some mapping work in Cornwall and the information 
that they are providing is really great. I have downloaded the landuse and land 
cover layers but there are gaps in coverage. Does this mean that the polygons 
need creating or are there polygons in existence somewhere that need 
classifying?

Many thanks
