Not to distract from the 2026 Q2 Quarterly Project: Addresses that just started; it would be good to have ideas of what topics could be the Q3 or Q4 projects.
While the talk page on the wiki has a number of suggestions. Please post in this thread what ideas you have for what might make a successful quarterly project (including any that already exist on the wiki).
What do you think makes for a successful quarterly project topic?
Looking on the talk page, I do feel like looking at NaPTAN again would be useful. I do a lot of rural landuse mapping, and bus stops are few and far between and not obvious from imagery.
In Wales, thereās Welsh language CommonName fields now too (although I am noticing some typos as I look through the Ceredigion stop data)
I would say that schools could definitely be revisited. There are various new and unmapped schools and also outdated objects where schools have closed or moved. Then there are school campus details which could be added or updated, like buildings, access roads, car parks, paths etc.
With updated Esri imagery in large parts of England/the UK? i have been fixing quite a few missing schools, buildings etc. Q3 could be a good time to review whatās already mapped and fill in the gaps.
StreetComplete is apparently the second most popular editing app by userbase these days so a building tracing sprint might actually do more for addresses in the long run than the this quarterās focus on addresses.
Winter is for tracing buildings, summer is for surveying :)
But I do agree, without (accurate) buildings, itās very hard to survey addresses. Itās very rewarding seeing people surveying addresses across Hertfordshire where Iāve spent hundreds of hours adding or splitting buildings.
Schools is a project we have done previously way back in 2016 and could benefit from revisiting. There is discussion on how to manage spread out campuses on universities too, so could include that?
Additional benefit of term time ending soon to make surveying easier?
Tracing aerial is better for the darker months, so if we are certain the imagery is better, we could have a campaign focusing on various areas in q4?
Any other suggestions?
A few ideas from my own mapping experience in Wiltshire:
**AEDs / Defibrillators**
AED coverage across the UK is patchy and data quality varies significantly ā many locations are missing entirely, and existing entries often lack `access=*`, `opening_hours`, or accurate operator information. Thereās also useful reconciliation work to be done against NHS and ambulance trust datasets (e.g. SCAS publish their AED locations). The real-world stakes make it a good project for engaging newer mappers who might not otherwise see the impact of their contributions.
**Public Rights of Way**
Summer seems like the natural time for this. PRoW data in England and Wales is inconsistent ā many footpaths lack `designation=public_footpath`, bridleways go unclassified, and PROW IDs from county definitive maps are rarely captured in OSM. Each council publishes its own definitive map data so thereās a ready cross-reference source. Rob Whittakerās UK-focused QA tools at [osm.mathmos.net](https://osm.mathmos.net) include some useful views for identifying gaps and inconsistencies, and would be worth highlighting as a resource alongside StreetComplete for any PRoW-focused quarter.
**Military heritage / WWII structures**
More niche, but thereās a real data asset available here. The Defence of Britain database and local Historic Environment Records contain thousands of pillboxes, anti-tank obstacles, and other structures that are either unmapped or tagged inconsistently. Cross-referencing against eDoB and council HER data could make a structured sprint feasible, and the subject tends to attract engaged contributors.
On the building tracing point ā fully agree that accurate buildings underpin so much else. If Q4 does go that direction, open street-level imagery (Mapilio, KartaView etc.) has improved a lot for UK rural areas and could be called out as a resource alongside the updated Esri imagery mentioned above.
Happy to help develop any of these further if useful.
Cheers,

Iām not against having another go at defibrillators, but from the comparison tool it looks like a significant chunk of the published list are considered restricted access even the ones that are considered public can still be inside buildings. Iām not sure what level of completeness we can really expect here.
I agree. Thereās little chance of verifying many AEDs that pop up on SurveyMe. Thatās certainly my experience of trying to find some of them. If they are not obvious outside mosr buildings then they remain unchecked.
SurveyMe should only be showing missing AEDs that are recorded as being public 24/7 ones in The Circuit, or are listed in the NDDB (accessibility isnāt defined for those, but I think theyāre mostly public ones). Some of the Circuit ones may be incorrectly classified, but I think most are probably mappable.
If you look at the second-to-bottom graph at Defib Matching History you can see how well weāre doing against public 24/7 AEDs in the Circuit. Weāve currently got just under 30% of them.
Thatās a fair point, completeness against the published lists probably isnāt the right goal, especially given how many are building-internal or restricted.
What I had in mind was more about tagging quality on the nodes that are already mapped: adding access=*, opening_hours, and operator information where itās missing, so that apps like OpenAEDMap can present accurate results to someone in an emergency. Even a small number of well-tagged, genuinely public AEDs is more useful than a large number of poorly-tagged ones.
If thereās appetite, a Q3 project scoped around āaudit and improve existing UK AED tagsā rather than āfind all the missing onesā might be more achievable.
Cheers,

I can only go by those Iāve mapped or not around Exeter. I think your tools are great, but you can only show what youāre given and that is limited by what others have entered. I need to check a recent new one near me that I suspect is inside a care residence, TBC. In the past Iāve spoken to various first responders on courses and they have varying opinions on the ābestā system to use.
Something Iāve been thinking would be a good project for some time is improving the mapping of public toilets, possibly combined with drinking water fountains / bottle refill stations. Both are important for tourists (particularly in the summer months) and other visitors, particularly those with various medical needs. Having these facilities well-mapped and searchable via apps like Organic Maps, OsmAnd and Co Maps would be really useful and is a great advert for OSM.
I can think of two that Iāve mapped that are listed as public 24/7 that donāt appear to be mappable 24/7:
I donāt think I actually succeeded in adding that many of them so this leaves me a little dubious as to the accessibility of the 24/7 locations. Maybe the Circuit have a way of letting you into the buildings if thereās an issue?[1]
In case of emergency wake the vicar? ā©ļø
The Circuit has two fields to express the accessibility of each AED. āAccess Typeā is either āPublicā or āRestrictedā, while āAvailabilityā is either ā24/7ā or āVariableā. My understanding/interpretation is that anyone should be able to physically get to āPublicā ones without assistance (apart from perhaps needing a cabinet code from the 999 operator), whereas the āRestrictedā may need someone to be contacted or asked to get hold of it. All four combinations are possible and occur in the data. (So e.g. an AED held in a permanently staffed security office would be āRestricted 24/7ā, while one on the wall inside a shopping centre would be āPublic Variableā.)
However, The Circuitās data isnāt always correct, so some AEDs may well be marked as Public 24/7 when theyāre not. The DefibFinder website also includes more specific opening hours that arenāt included in the data. A while ago, when I looked at some suspicious ones I think I found examples of AEDs that were claimed to be 24/7 but had restricted opening hours recorded. I was surprised there werenāt some data consistency checks.
If anyone wants to formally propose any of the ideas here, or anything else, for the Q3 project, please see the 2026 Q3 Project Proposal Thread.
@campbelltree Similar project: Ceirios performed a project to update all Welsh language teaching schools in October 2025.
Not quite done with this - I still have North Wales counties to go! 
I also need to think of a way of tagging dual stream/transitional schools, but the categories have changed fairly recently so Iāve been holding off on tagging those.
I donāt think Iāve seen it mentioned before, but speed limits might be an interesting one. Speed limit data is pretty spotty in the UK, and many areas have or are rolling out new 20 mph limits in urban areas.
