Hi UW Maddie,

I'm looking at this changeset, specifically the intersection of 18th and Jefferson, for example way 901474220

2. Why does west...
2 ~ 1 month agoUW Maddie 1. I have no idea why and I did not put the cycle tags on them according to the edit history. Some mappers have decided to tag pedestrian crossings that connect wider cycle paths/routes as cycle paths or cycle & foot paths. I don't always know the route details or their reasons, and that is...

FYI it sounds like the general consensus is that this scored surface treatment (on https://www.openstreetmap.org/node/8279999097) doesn't count as tactile paving--see https://www.openstreetmap.org/note/5132105 etc.
2 ~ 2 months agoUW Maddie Alright I've taken this into account. I was waiting for word of a consensus to change them. At some point I will do a mass replacement in the gigantic area of Seattle that I added these to
3 ~ 2 months agopwbriggs
♦218
Sound good, but I don't know how these could be mass-edited: i.e. how do you differentiate between proper tactile paving with tactile_paving=yes and ramps with surface treatment that are tagged (incorrectly, we've now decided) as tactile_paving=yes too?
4 ~ 2 months agoUW Maddie That is visible in imagery. It is possible to manually de-select objects in JOSM to only apply the tag change to some of the ones that were searched for, so I can de-select any that are genuinely tactile (or not visible aerially too). This will not be done until after the 2025 King County Orthoimage...
5 ~ 2 months agoUW Maddie The last point is about there possibly being survey-verified new construction in the short period between 2025 KCOI captures and its release date. There will be a small number of them I'm sure, but that's more than 0 so I'll need to check manually for any curb edited last by someone e...
6 ~ 2 months agoUW Maddie I intend to, around the same time, use a search for "tactile_paving=no" to find examples where 2025 imagery shows a tactile paved curb tagged as not tactile in order to locate crossings that need updating, though for those it will require geometry edits too

I was curious what was the idea with https://www.openstreetmap.org/relation/11207531/history I've not seen anything like it. Maybe an experiment that didn't pan out? hmmm
2 ~ 1 year agoUW Maddie Yes, I was under instruction to make relations out of "complex intersections" at the time. I do not know what these relations were supposed to be for, but they don't seem to need me to add them anymore so I stopped a while ago.

Hi 0wu,

I think you're being much too generous with what counts as a "footway" in changesets like this. I just walked along Dayton Ave N an hour ago, and some of the sections you've tagged as footway are just a gravel shoulder. The east side, just north of N 85th St, doesn...

Hello! This changeset reverts the updated alignment of reconstructed curb ramps and crossings along N 80th St. This is one of the streets that I sent in the list that you asked for.

Please check the version history of an element before adjusting it with outdated imagery.

Thanks!
2 ~ 3 years agoUW Maddie I wasn'y using outdated imagery for this, I saw your message about the construction, this is referencing the streetside imagery which is new enough to include the newly constructed curbs, some of which were actually missing
3 ~ 3 years agoUW Maddie And I know they're all new because they have tactile pads absent from the aerial imagery and match mapillary feeds from 2021 and 2022

Hi 0wu, thanks for the reply. I'm referring to the angles of the curb ramps which changed after the construction. For example, this changeset moves some ramps back to the ~45 degree angle shown in the older Bing aerial imagery. However, the construction replaced a few of these with straight ang...

To access the imagery in the editor on openstreetmap.org, open the "Background Settings" panel on the right, and choose the "King County Orthoimagery (2021)" option. The imagery offset settings are at the bottom of the panel.

To improve the representation of those wide curbs when using two nodes, we could connect both nodes with a way tagged with:

barrier=kerb
kerb=*
tactile_paving=yes

This way they're connected by a single feature for anyone who happens to want that data.
9 ~ 3 years agoCy R

Ah, I figured out how to get the KC 2021 imagery into the tasking manager:

1. Open the background settings panel
2. Choose the "Custom" option

10 ~ 3 years agoUW Maddie I got it to work. And yes I like this idea of mapping the wide curbs as 2 rather than 1 for this purpose so I'll start doing that, but I'm not sure if the extra way is necessary

At least ways 788344891 and 788344901 appear (at ground level) to be shoulders, not footways. Is there some indication I'm not seeing that would make them footways instead of shoulders?
2 ~ 3 years agoUW Maddie How do we tag shoulders? We're tagging these as footways to specify a walkable path separated from the road for opensidewalks. I don't see any documentation about how to tag shoulders for this purpose. The only thing the wiki calls "shoulders" is something for cars to pull aside ...
3 ~ 3 years agoUW Maddie The reason why I didn't label them as sidewalks is because these paths are not separated from the road in any way like a proper sidewalk, making them not technically sidewalks but rather a type of foot path without a specific tag designated for them. I cannot use the existing shoulder tag becau...

2 ~ 3 years agoUW Maddie But those were not sound signal tags, they're foot signals tags I was told to input for when visual pedestrian signals are present.

Hi 0wu,

I was biking down Sand Point Way today, and the sidewalks you added along that street mostly don't seem to exist. Rather, I just saw a regular shoulder on each side, which can be used for car parking and isn't dedicated to pedestrians.
