2023 quarterly projects ideas and feedback

GL Gareth L Public Seen by 86

We want to announce all the quarterly projects for 2023 in advance.

This will be in early December.

Tell us what quarterly project ideas you have or think are good! Here's an email sent to talk-gb earlier this month:

We had a call on 1st of November to discuss potential topics. Here’s a digest of what was raised.

I’d appreciate it if you could:

  • Add to these any other topics to consider with potential data sources, metrics, outcomes etc.

  • Add to the already mentioned topics ideas that could make it a good quarterly project.

We referred to https://wiki.openstreetmap.org/wiki/Talk:UK_Quarterly_Project as a starting point to the conversation.

There was a recap of what a quarterly project should be or achieve.

Easy to measure metrics can make it much clearer to monitor progress and success of a QP.

Some quarterly projects are to bring in brand new mappers, or get novice mappers to map more.

Other quarterly projects are to focus on enhancing a particular subject area on the map, resulting in more detail, coverage and/or tools.

Buses and public transport.

  • Are all bus stations mapped in detail (or at all?)

  • Are bus stops in the correct location?

  • Maintenance on bus route relations

  • Is there a better way we can present the NAPTAN dataset to mappers to help identify misplaced bus stops or missing bus stops? There was an idea floated of having an overlay that could be shown in iD/rapiD/josm etc. that could do a diff of where NAPTAN thinks a data point is compared to if/where it exists in osm and indicate that visually. This wouldn’t necessarily show the exact location of it as recorded in NAPTAN but just highlight a square on the map to direct in person survey, aerial use, streetlevel imagery etc. Added stretch goal doing a diff within NAPTAN itself so it would highlight where something has moved in that database since last update.

  • There was additional discussion on detail mapping other transit stations (like railway stations) though surveying these and tagging for these can be quite complex.

Places of worship.

  • Adding locations that are missing.

  • Enhancing existing datapoints with religion, denomination, wikidata links, etc.

  • Are there compatible 3rd party datasets which could help measure progress and direct surveys?

  • What other adjacent mapping activities could be included?

EV charging points

  • A lot of discussion on this as there are many databases that are all partial.

  • A guide to clearly identify and record the capabilities of common chargers in the UK (compatibility, power delivery, etc.)

  • The government has lots of plans about making this more open in the future using ‘OCPI data standard’ however this looks unlikely to be implemented in 2023.

  • Possibility of scraping through planning applications to direct surveys

  • Including H2 filling stations

Galleries, libraries, archives and museums + public art

  • Could we compare with local authorities lists for libraries (even with more libraries being volunteer run)

  • Public art installations, compare with wikidata and link to node in osm if possible.

  • Verify art installations still exist

  • A lot of metrics would need to be calculated up front.

Notes and fixme’s

Meta quarterly project

  • Nothing to do with the company

  • Focus on improving the wiki or other documentation sources

  • Collate and share data sources for the UK in one place.

  • Where to find the dataset, how you could use them – Think how many times you find a useful data set later than you’d like.

Welcome new mappers

A road and motorway corridor detail + motorway gantries?

  • Using the ample streetlevel imagery, enhance the detail along the corridors of A roads and motorways.

  • Include motorway gantries as they were reportedly under-mapped in 2020 (need to recheck current state)

  • Difficult to measure any metrics on this.

Regarding charging points, I mentioned on the last call that I had permission from Source London, who are one of the big suppliers in London, to use their charge point data.

Would someone be able to help me conflate them if this is a potential way forward? I have the dataset available.

Having one supplier sharing their data may help persuade other suppliers to supply theirs too.

It would be a great start to an EV Charging Points project. I'd also like to know about the current vested interests in charging point mapping. Sites exist, can they be convinced to use and contribute to OSM as a datasource?....in short, these don't need to be done ahead of a Quarterly Project, they are the QP


Steven H Sun 27 Nov 2022 8:48AM

When you say "vested interests" do you mean ZapMap or the charge point providers themselves?

It would be great if the providers could use OSM as their master map. I wonder why they don't already? Maybe one fear is the risk of someone maliciously adding phantom charge points to the map. Is there an OSMCha query they could run to monitor this?

I did fill out a page of the OSMWiki about the potential data source I made most progress with. Looking back at the article I might have made it sound like the data was generated on a gmap - I don't know how the geopoints were generated, and was speculating about a potential problem.

I've not read the details on the wiki yet, but I'll try and help with the conflation process.


Steven H Sun 27 Nov 2022 10:12PM

Thanks @Cj Malone and @joeldn for the offers of assistance, what's the best way to proceed with this? I don't want to swamp this thread with charge points chat if it's not relevant to the monthly project! I've not used Loomio much before, do we start a separate thread here, or on the talk-gb mailing list, or something else?


Jez Nicholson Sat 26 Nov 2022 12:21PM

An idea from Jerry's post on Talk-GB: a focus on pubs. Resurveying/detailed mapping/FHRS/closures


Jez Nicholson Sat 26 Nov 2022 12:23PM

Another idea from when I put a call out to map buildings in my Mother-in-law's village when I was visiting: a group blitz of remote building mapping + on-the-ground StreetCompleting for specific places.


joeldn Sun 27 Nov 2022 4:22PM

hi @Steven H, i'd be keen to help out with conflating ev chargepoints from open data. with thanks to @RobJN, i previously conflated a batch import from GLA charge point data in 2019 (OGL is compatible with ODBL) although never went ahead with the final import. that particular instance of ilya zyerev's osm conflation tool has now stopped running on glitch, but i could get it going again or review other options.

Places of worship

So it's "Religious Buildings" included in some OS Open Data products. It is close to our definition of place of worship. In terms of location, there accuracy is obviously perfect. In terms of metadata, there is nothing, also it's not great on age. It has some old things in there, and presumably missing new ones.

Metadata is more interesting. I don't know of any usable dataset for this, but that just means our dataset is more valuable, we should draw attention to it. It's possible to get data for for some of the big ones, but it's not usable for us.


Gregory Marler (former Director) Mon 9 Jan 2023 10:02PM

If OS Open Data has a religous buildings layer then that could be helpful, as would looking at existing OSM data. I wonder how many are mapped but without religion/denomination or name? You often get that data by OSM's favourite method: going outside and looking at the signs!

I've already done a video tutorial about mapping religious buildings: https://www.youtube.com/watch?v=7lVuKtNgrkY

If there was a quarterly project on this I would let some people know that might want to put some time into it.
