confusing style for highway=pedestrian

[mnalis]

highway=pedestrian has strange style, with divider line in the middle, which makes it look like two streets.

It is confusing to users, eg. https://www.openstreetmap.org/note/2259724 or https://www.openstreetmap.org/note/2974300

Perhaps it could be drawn to look more like regular footway?

[westnordost]

Sounds like a bug. I can not remember there is some explicit code in the style that would do this.

[mnalis]

Looking around at https://streetcomplete.github.io/streetcomplete-mapstyle/?provider=jawg&style=dark, the problematic "line in the middle of pedestrian street" is visible in both dark and light mode, but not in satellite mode, where it looks normal.

[Helium314]

The responsible part is

streetcomplete-mapstyle/layers/land.yaml

Lines 123 to 126 in 2ecce80

	lines:
	color: global.square_outline_color
	width: function () { return 1/4 * Math.log($zoom); }
	order: 30

which also draws the "double" outline of squares.
IMO things also look quite ok without this part

[westnordost]

Hm well, the outlining works correctly with buildings, so maybe there is a bug.

[mnalis]

hm, that function() is inside pedestrian-areas: yaml section, and highway=pedestrian (which this issue is about) can be used not only as a way, but also as an area. Could that be related to the problem?

i.e. that style should be applied only to areas, and not to regular (non-closed) ways?

It looks like outlines of squares are displayed as roads. When excluding pedestrian roads from normal road style, the outlines of squares are nice, but then of course non-area pedestrian roads are not displayed properly (only as line with square_outline_color).

The extra bubbling outward of the area is also ugly in the places where I encounter it. Mostly around swimming pools, but a couple other places too.

@Joxit Is there any possibility to distinguish "outline of highway=pedestrian area=yes area" and "highway=pedestrian line"?

From what I see Jawg data is not allowing this.

[matkoniecz]

I tried removing

                lines:
                    color: global.square_outline_color
                    width: function () { return 1/4 * Math.log($zoom); }
                    order: 30

and I think that with current limitations it is overall an improvement.

Though one of results is no longer displaying minor inner borders of pedestrian areas, like https://www.openstreetmap.org/way/304011759

(transparency difference is an unrelated issue)

[westnordost]

@matkoniecz what data is exactly in the jawg tile set is documented here:

https://www.jawg.io/docs/apidocs/maps/streets-v2/

Note the map on top, you are able to zoom in and inspect exactly what tags are set on the individual objects.

I did this to confirm that there is nothing allowing distinguishing them.

(oneway and presence of names is not reliable indicator)

Hi there, so you want to distinguish a Line from a Polygon ? With MapLibre GL, the style spec allow us to apply style on LineString or Polygon, is that you are looking for ?
