Open GretaTimaite opened 2 years ago
youthmappers could help us with organisation. Alas, there's no chapter at Leeds Uni.
Missing maps could be helpful (from our teams chat Greta), though this is focused on hosting mapathons to map potential crisis areas to aid in crisis response it seems.
This is active travel crisis @hulsiejames!
Thumbs up from Kylie on the mapathon.
She's asked us to consider the following:
@hulsiejames @Robinlovelace, do you think it is time to contact Gregory Marler (aka LivingWithdragons) for a potential collab? He might help to answer some of these questions as well.
My initial thoughts about the whole thing are the following:
- What is the anticipated resource needed
Finance only or finance and staff support time? Can you estimate a figure you might potentially need
- Venue
computer cluster 11.06 next to LIDA may be available for this depending on the date, and has capacity for 50 persons
- Timings
it seems wise to go for a date in October as this avoids the intensive teaching roster in 11.06 with the new term start in September
Today we're meeting Gregory and Kim, so here's a list of things that we might want to discuss:
I'm sure more questions will arise as we start discussing these things but it's a starting point? Feel free to add any other points that pop in your mind.
=====
Also, I think it might be interesting to measure the impact of this mapathon through added data. I can come up with a couple of simple ways of doing it.
First approach:
Second approach:
These questions look really good and on point. I can't think of anything I would add for now, but will have a muse over lunch.
I think Gregory should be able to help with a lot of the specifics of organising a mapathon (max participants, timings of event etc.)
Looking forward to the call.
Incredibly rough meeting notes on HackMD. I am writing these up in neat and will post here...
Great, many thanks James for doing this!
After the meeting I thought we could have asked to record it 😅
TIME
date and time for the event
- End of October early November (dependant on LIDA room availablilty). Gregory mentioned that you don't really need more than 4 weeks notice unless you're looking to host a large event (nation wide reach). Sautdays & Sundays obviously most desireable with work/academic commitments during the week, but if required Mondays and Fridays work best during the week. duration
- Gregory mentioned that when doing detailed mapping, it becomes quite intensive after an hour of mapping so shorter is sweeter, but suggested two mapping sessions with tea/coffe/snacks inbetween, say 45-60mins mapping, 30-60 min break, another 45-60mins mapping.
- Max 2 hours for into talk, what is OSM and why is it important, how to map features, what tags are actually useful for active travel/accesibility (this can probably be done in less than 2 hrs).
- Finally once mapping is over, meet up for final drink/snacks, and a discussion. Back in the day this was a really useful part of the mapathon as people could discuss mapping ideas and features they discovered whilst mapping "I found this intresting bicycle barrier, how should we be mapping these" etc. Gergory mentioned that this part was always really useful.
- All in all, perhaps max 6 hours give or take(including an intro talk, tiny break, first mapping session, break, second mapping session, final discussion and snacks)
SCALE
how many people do we expect to attend? what's the maximum number of participants we prepared to manage?
AUDIENCE
who's our target audience?
- Gregory mentioned that it is helpful (but not crucial) to have a group of mappers who feel they can get something from the mapping event... i.e a local walking group would likely be a good target when looking to map local walking routes, similarly a local cycling group is useful for mapping cycling infrastructure, acadmeics who may have intrests in analysis of specific types of OSM data, etc. LIDA, School of Geography, ITS
- All seem good suggestions to myself
LOCATION
venue for gathering and training
- Believe LIDA can facilitate - follow up with email. mapping location(s)
- Gregory mentioned the concept of cake slices. Once you have identified an area you would like to be mapped (I asusme centred at the host location), draw a circle around this area. Then, split the circle into numbered segments. When mappers come to the mapathon, allow them to select a segment or two in the teams of two or three, this is then the segments they will walk in the mapathon.
- Building on this, we could plot the density of tags describing active travel infrastructure in Leeds as a heatmap, identify cells of the heatmaps with the lowest densities of active travel tags and use these as our segemtns?
EVENT From the above, the general structure could be something like:
General comments from meeting
It is a good idea to have a mapathon focused on active travel / accessible active travel (in general a specific focus) as Leeds (in general) is already mapped quite well. Gregory liked the idea of using Streetcomplete and IOS go (I think is the name) as facilitates mapping on the go, rather than notepad & pen --> computer editor approach.
Gregory mentioned that mostly individual or small teams (2/3) of mappers is a better idea, with a more experience mapped joinging a team should all team members be novice.
Gregory can do an introduction into OSM, what is OSM and why is it important, how OSM gets used by people and why it is useful to map the world for OSM, and how to map for OSM. Obviously we can split some of this up so not such a large workload
It is a good idea to have someone in the host location at all times. If mappers are getting bored before an hour session is up, or they have already mapped their segments then they can come back to the lcoation, get an early drink and have a chat with one of the hosts, or even ask for a new, nearer location.
After the meeting I thought we could have asked to record it
I wish we had :grinning:
Sounds like a productive meeting! Sorry for missing it, look forward to helping to make it happen, exactly what is needed.
@hulsiejames and I had a quick chat yesterday with Kim. Here are a few key takeaways:
I think the most important consideration is date. Looking at the calendar I think the following days are apt:
Any days that you for sure know you cannot make @hulsiejames and @Robinlovelace? Or any other suggestions? This should be a half-day event in the morning/afternoon, fyi. If all of these days look good for you then I will send the dates to Gregory to inquire if there's the one he prefers most?
Many thanks for instigating this Greta, any of those look good to me!
Hi Greta, Friday and Monday (28th / 31st) work best for me as my tenancy runs out onf Friday 4th November.
I'm not sure how much Halloween on 31st Oct might be an issue? But I'll send an email to Gregory ASAP to find out which days work best for me and will highlight that these are the days that we have some preference for.
I'm not sure how much Halloween on 31st Oct might be an issue?
Hopefully not too much as we are planning on arranging this within the day.
Just thinking if young people might be more into prepping for the Halloween rather than going to a mapathon, but I don't know what's the Halloween culture in the UK.
Halloween themed mapathon? Could be amazing, thinking 'trick or map'!
I forgot to link my commit to this issue. So to keep it updated, here's a link to the mapathon abstract: https://github.com/udsleeds/openinfra/tree/main/abstracts
Just to confirm, @Robinlovelace and @hulsiejames you're on board with the mapathon description? I really haven't had time this week to follow up with you or Kim but will send an email to her by Monday morning to confirm the date (2022-10-31), so she can get the required approvals in time.
I'm onboard, please send a link to the latest version, should know where that is :see_no_evil:
Sorry, I forgot to paste it. See .Rmd here: https://github.com/udsleeds/openinfra/blob/main/abstracts/mapathon.Rmd
Feel free to edit it, so I have the final version.
To do as discussed today:
Gregory mentioned the concept of cake slices. Once you have identified an area you would like to be mapped (I asusme centred at the host location), draw a circle around this area. Then, split the circle into numbered segments. When mappers come to the mapathon, allow them to select a segment or two in the teams of two or three, this is then the segments they will walk in the mapathon.
On this - I want to create a heatmap around LCC based on the density of active travel OSM features (kerb tags, tactile paving tags, etc - additioanal thoughts welcome).
Based on this, we can then create the 'slices' / segments to for mappers to visit.
Thoughts and suggestions are welcome!

We could do this but I'm not sure it's really necessary? And how would you measure density that is not a rather crude approximation?
I think the easiest thing to do is split LCC into equal parts, or maybe by street so we can later use ohsmore (is it what the osm history tool is called?) to explore the difference a mapathon made. Perhaps we can send results to the participants too (I think Gregory suggested this). We can mention this in the email as an incentive.
But if you want and have time to play with the heatmap idea -- go ahead. Even if it fails, it's good to have an empirical evidence of why.
An idea while typing this: maybe we could print out maps so participants can highlight what was covered.
EDIT: approximation is not a bad thing by any means. Sometimes it's all one can measure.
And how would you measure density that is not a rather crude approximation?
I suppose it would be an approximation to be honest, my thoughts were if we split LCC into equal parts using a grid and count accessible active travel features within each grid to make the heatmap, as done here but with collision data: https://urbandatapalette.com/post/2021-08-tessellation-sf/
I think this might be mroe of a fun idea to play around with though rather than target where needs mapping. Just because an area has small amount of mapped accessible active travel infrastructure features, it does not necessarily mean this area "has not been mapped" - there may just be lacking infrastructure there.
As such, the best approach may just be sending people out to specific areas so that we are sure these areas have been covered. Thus, any areas with little accessible active travel features will be due to a lack of features, and not "this area just hasn't been mapped yet"
An idea while typing this: maybe we could print out maps so participants can highlight what was covered.
I think this is a very good idea, as allows us to state the above confidently (Thus, any areas with little accessible active travel features will be due to a lack of features, and not "this area just hasn't been mapped yet" <-- As we know which areas have been mapped!)
Another way we could do the above is by looking at user ID's and changesets to see where people have mapped.
User ID's is a bit tricky I believe - these are not included in data providers extracts (Geofabrik, bbbike, I beieve) but are obtainable from some route. (I remember hearing somewhere, maybe SOTM, that if you query the OSM database when logged in through your own account, one does get access to user ID's)
and count accessible active travel features within each grid (My first paragraph)
Robin made a good point on this after the ITS hackathon yesterday. We should definately try and get involvement from people with disabilities / impaired mobility group(s) as to what features are useful to be mapped to allow route planning for accessible active travel routes, otherwise there may be a number of features we overlook / take for granted!

There's a research group based at Leeds University with whom I met in January to discuss exactly this. We didn't end up following much after, alas. I can connect you and @Robinlovelace with them. Vikki attended that meeting, so maybe Robin remembers them too. I could try emailing them about the mapathon but it's a bit short notice...

I think Gregory also suggested asking participants to create accounts, so we can validate tags. I think this is a sensible approach even if takes extra work for us. Perhaps we could create a second event focused on validation :D
Anyway, I think accounts is a good idea. TBH, both could be combined

Yes I think this is an excellent Idea. Even if nobody is available to participate / help in the mapathon, consulation on the sort of street features that lead to exclusionary infrastructure is important imo!

Yes I like this - be it creating an account on the day or providing us with the user tag of an existing OSM mapper.

Good point, @GretaTimaite could you try contacting them and asking if they would be interesting in participating?
Good points from e-mail discussions.
Ameena Berkowitz
I would suggest you get in touch with a local Leeds disability group, and potentially via the Universities in Leeds. A quick google search under Leeds Disability groups brought up several.
Including ableize - DREAM - LDPO (mentioned below) - DIAL LEEDS - UoL Disability Service also comes to mind along with the Inclusive Public Space Project
You could also potentially engage young people with an interest – you could see if Modeshift has an Active Travel Ambassador school who might be keen to get involved.
Chris Pryor, Active Travel Ambassador Coordinator (South & West Yorkshire)
Could also ask Transport for All to let their members know about this. Obviously this is of specific interest for wheelchair users, but might you think about what criteria would be useful for other disabled people to know about that might be mapped at the same time? I expect T4A could help you with this.
Juan P. Fonseca-Zamora
Has contacted a friend who works with LDPO (Leeds Disabled People's Organisation), although they are currently not in Leeds, they will pass on the information to see if anybody from the organisation can join on the day.
I will look at getting an email sent out to these people/organisations tomorrow for event participation and consulation on accesible features that we should be mapping!

^ Cool project I have just found on mapping accessible infrastructure. However, very limited coverage for now:
Let's organise a mapathon in Leeds focused on accessible active travel infrastructure?
