@bluestarfish Does Missing Maps still do in-person mapathons?

@derickr sadly it's not as common. HOT are trying to do one roughly every three months, but it really depends on their staff movement. I'm not aware of one coming up. I miss them a lot!!

Gina Peter Banyard Mar 3

@bluestarfish I'll see if I can join, and maybe get help to map buildings in Chiswick as my whole neighbourhood is just *empty*.

And I'm not super comfortable with the satellite imagery as Bing's seems to be quite outdated :-/

@Girgias we'll be mapping in Chad and Ivory Coast today, but do please come along if you'd like to. It's a friendly bunch, and some of us *are* Londoners too 😂 (My neighbourhood is also quite devoid of buildings ...)

Derick Rethans Mar 3

@Girgias I would suggest not to use Bing for adding buildings.

Instead, I use the "NLS - OS 1:1,250/1:2,500 National Grid Maps, 1947-63 - TQ" layer as reference.

I draw from that, and then verify it's still up-to-date by walking around and looking what changed. Having an existing reference makes it a lot easier, and on top of that you get (some) address information too.

To do terraced buildings (like south of Chiswick High Street), I created the Uberterracer plugin: https://josm.openstreetmap.de/wiki/Plugins

Gina Peter Banyard Mar 3

@derickr Do you need to line up the layer? Or is Bing just very misaligned?

Derick Rethans Mar 4

@Girgias Probably both! You might need to get a proper GPS (not a phone, which does AGPS) to establish ground truth.

Alerta! Alerta!Mar 4

@derickr How much difference does AGPS vs GPS actually make? In terms of accuracy?

Gina Peter Banyard Mar 4

@derickr yeah thinking of doing that, any recommendations?

Derick Rethans Mar 4

@Girgias I use my sports watch for these things. On multiple days for an average.

Steven Hirschorn Mar 4

@derickr did you do Turnham Green Terrace? Someone mapped that with building parts and separate floor mapping, which I might have botched once by using an editor that didn't make that complexity obvious.

Derick Rethans Mar 4

@milh0use I see @Girgias just updated https://www.openstreetmap.org/way/209434700 — and it indeed looks wrong now (not due to her change). But it was Paul, not me, who added it in the first place (but at a mapping party I was at too). Let me see if I can fix it.

@milh0use @Girgias I've added a building tag, but I see that almost all the bicycle parking stands on that street are doubled (some added by you, and some by @Girgias too).

Gina Peter Banyard Mar 4

@derickr @milh0use there are a *lot* of bicycle stands on Turnham Green Terrace

Steven Hirschorn Mar 4

@Girgias @derickr yeah, do you mean doubled in terms of twice as many nodes as there should be, or are you looking at the capacity?
I've tried on and off to get Ealing Council to record the bike parking they add themselves to OSM with no luck so far. I asked for a list of the recent installations but their data isn't great at the moment.

Gina Peter Banyard Mar 4

@milh0use @derickr Turnham Green Terrace is in Hounslow tho, but yes if the Councils could provide the data that would be great. :)

Steven Hirschorn Mar 4

@Girgias as much because they could then use the data to report where more bike parking is needed, as to put bike parking on maps (which is also useful)
I feel that Ealing focus too much on placing them near shops where you rarely find a shop without a Sheffield Stands outside, but not enough in the gaps in between to lock up when you're visiting residents.

Derick Rethans Mar 4

@milh0use @Girgias No, duplicated nodes, not capacity.

Derick Rethans Mar 4

@Girgias @milh0use I know, but nearly all are duplicated. Nodes nearly on top of each other.

Steven Hirschorn Mar 4

@derickr I wonder if that's my fault and I added them thinking they were missing when I just need to refresh the EveryDoor cache?

Derick Rethans Mar 4

@milh0use It's possible. I didn't see it which ones were first.

Steven Hirschorn Mar 6

@Girgias incidentally, 1) thanks for fixing so many of the notes I added to the map, you must be bored of "Ealing council say there should be a Sheffield Stand here" 2) if there's a big empty gap on the map, you know what you need to do 😉
I added my street. Then the neighbourhood. Then I had to draw a line somewhere and decided to stop at the North Circular. Wynndale (is he on Bluesky?) seems to be filling in the gaps south of the river.

Gina Peter Banyard Mar 6

@milh0use I quite enjoy it actually, and I've been adding a bunch of notes myself! It also gets me out of my flat and get some fresh air! 😁

Currently focusing on adding all the crossings and EV charge stations I find on my walks and update the opening times.

But must say Ealing has been adding quite a few EV charge points where I lobe in the last few months.

Steven Hirschorn Mar 6

@Girgias the crossings you're adding keep coming up on the OSMCha feed I set up! Pedestrian routing FTW!
I did get as far as starting a bulk import wiki page for car charging as I contacted the suppliers for permission to use their data and also worked out how to scrape the data, but stumbled on the risk that they might have created the geo references using a Google geocoder.

Steven Hirschorn Mar 6

@Girgias it would be great to just get a feed of georeferences to add to OSM.

Steven Hirschorn Mar 6

@Girgias I presume you've seen this OSM based game?

@milh0use I have not! I'll have a look. :)

Steven Hirschorn Mar 4

@bluestarfish are these posted to OSMCal? I get to about 1 in 3 of the OSM London meetups by finding out about them via OSMCal. I wondered if HOTOSM/Missing Maps mapathons were still going - it was a mapathon that started my addiction!

@milh0use yes they are! here's the next one https://osmcal.org/event/4232/

@bluestarfish I don't know how I've managed to miss them!

@milh0use they are how I started too! it moved online with COVID and never really moved back offline again, but they still trundle one every month.
