[Talk-dk] Tagging of No Pedestrian Crossings

[Theodore Ahlvin via Talk-dk]

Hejso! The Apple team has recently been investigating pedestrian navigability 
in Denmark and we’ve come across some issues that would be best handled with 
consensus from the OSM Denmark community.

Often streets intersect with dual carriageways where there are no crossings 
marked for pedestrians. For example, how Fyensgade intersects with Viborgvej at 
56.4631795, 10.0156701 (way 30155258). In this situation, and similar 
situations across the country, it could be dangerous or illegal for pedestrians 
to cross the dual carriageway. These crossings can also be all but impossible 
for individuals with disabilities using OSM to navigate. Our team has been 
adding ‘foot=no’ tags to these sections, but after a conversation with user 
MikkoLukas (https://www.openstreetmap.org/changeset/76508518 
) we’ve decided to 
investigate a solution which the rest of the OSM Denmark community agrees on.

There are several potential solutions to this problem. It could be argued that 
‘foot=no’ could be inferred from Danish law on jay-walking and added to these 
sections. It could also be argued that ‘sidewalk=no’ or ‘sidewalk=none’ can be 
added to these sections, and would be accurate to ground truth, and used to 
discourage pedestrian crossings. Finally, it could also be argued that 
‘crossing=no’ could be added to these sections, as it true to what is on the 
ground and the most accurate tag to describe why pedestrians should not be 
using these crossings.

I think this information would be very valuable to include in OSM for both 
individuals with disabilities as well as for pedestrians. What solution to this 
issue would the OSM Denmark community prefer going forward? Our team can go 
back and add whichever tags are decided on in place of the ‘foot=no’ tags 
previously added. Med venlig hilsen,

Re: [Talk-dk] MapRoulette challenges for Denmark

[Andrew Wiseman via Talk-dk]

Hi all,

I just updated the MapRoulette challenges in Denmark with new OSM data, take a 
look: https://maproulette.org/browse/projects/39285 


Hope it’s helpful! Thanks!

 Hello OSM Denmark,
 
 This is Andrew from Apple’s Maps team. We’ve been working on the a few 
 road issues and buildings for some time 
 (https://github.com/osmlab/appledata/issues/69 
  and 
 https://github.com/osmlab/appledata/issues/118 
 ) and recently used our 
 Atlas data analysis tool (https://github.com/osmlab/atlas 
 ) to look for a few types of potential 
 issues, such as roads with sharp angles and buildings that intersect 
 roads. I posted the results of those checks on MapRoulette, a tool that 
 lets you go through potential issues one by one and either correct them or 
 indicate they are not a problem. I wanted to let you know they are 
 available in case others wanted to try fixing some of them — I also plan 
 to go through some of them myself. 
 
 In MapRoulette you can either pick a random task to fix or click on a 
 specific one. If you want to do tasks around a certain location, such as 
 somewhere you are familiar with, you can click “more options” then “load 
 tasks by proximity.” 
 
 The checks are:
