[talk-au] Fwd: Assistance with ongoing disagreement regarding intersections

[osm.talk-au at thorsten.engler.id.au]

This is nonetheless correct mapping!

 

What you are seeing it the resulting impedance mismatch from using linear ways to map what on the ground are actually areas.

 

That sort segment at a sharp angle only exists for connectivity purposes. And the data makes perfect sense when seen in the context of all tagging around it.

 

Please look at this:

as you can see from the dotted outer lines on that “connectivity” way, it’s tagged as placement=transition

 

That tells any data consumer that wants to care about it that the position of the way does not actually reflect a fixed relation to the area of the way.

 

>From the available data, a data consumer can derive the information that the actual “per lane” connectivity and lane area follows the line that I drew in red.

 

As I’ve said before. OSM is not a map. It’s a geospatial database. A data consumer that wants to draw a map is able to derive the necessary information from the totality of geometry and tags used.

 

Cheers,

Thorsten

Hello,

Things have escalated somewhat: https://www.openstreetmap.org/changeset/118091243

Yeah, we now have the situation where turn left slip lanes have been mapped as sudden sharp angles, rather than gradual turns, which just looks wrong!

Thanks

 

Graeme
