Oh ! Right, user AtonX  added them

Looks the right way of doing it then.

Mathieu, what you did is what Seppe is suggesting to do in Ghent, if I
understand correctly.

In Brussels you have both areas and lines.  The routing uses the lines. In
Ghent, in a lot of places, the lines were removed.

Re: [OSM-talk-be] road axes in pedestrian areas

2016-02-23 Thread joost schouppe 
We map rivers as lines, then -add- water polygons to them. The same logic
should prevail when it comes to roads IMHO : the abstract road axis should
remain after someone maps the exact walkable area in detail. I'm cases
where the axis is missing, I'd say add it in.
To increase practical usability, I believe it is best to share a node where
the axis line enters and leaves the polygon.

Re: [OSM-talk-be] road axes in pedestrian areas

2016-02-18 Thread Santens Seppe 
Hi Glenn,

To be clear: I didn't mean merging datasets, but just drawing the axes from the 
GRB WMS. I'm asking this question because I'm looking at pedestrian routing 
through the pedestrian zone in Ghent. Say we take Poeljemarkt / Emile 
Braunplein and Sint-Baafsplein as an example. A route planner seems to guide 
you along the edges of the pedestrian area or make a detour along highways that 
are already in OSM, e.g. like this [1]. If you look at the GRB map [2], you see 
that Agiv has drawn road axes through (most of) these squares/areas. Of course, 
there are endless possible ways to cross a square (but also some impossible 
ways). However, the road axes in the GRB usually seem to be a "logical" or 
often used way. When adding these axes to OSM, the routing algorithm could 
"snap" to them, like in this example: [3]. I added the road axes in this 
example myself, but afterwards wondered whether I should continue doing this, 
hence my email. Maybe this is too much mapping for the renderer/router?

Hi Seppe,


I would hold off merging GRB data like axes into OSM.which is the
dataset you found these in?  See
http://wiki.openstreetmap.org/wiki/WikiProject_Belgium/GRB

What is the added value in your view ?

Re: [OSM-talk-be] road axes in pedestrian areas

2016-02-18 Thread Marc Gemis 
On the help forum, someone asked a similar question the other day:
"what can I do to improve pedestrian routing ?" [1]
So far, there was only 1 answer: stating "do not add separate lines
for sidewalks, improve the algorithm" and pointing to some thesis.
Perhaps you can get inspiration from reading the link in the answer on
the help site on what we need to do for pedestrian routing.

[OSM-talk-be] road axes in pedestrian areas

2016-02-18 Thread Santens Seppe 
Hi all,

Are there any sensitivities I should know of when adding "road" axes in 
pedestrian areas? My idea is to add to OSM the axes that are in the GRB (Agiv) 
to aid pedestrian routing. I've seen this in some places, in others not (yet?). 
Is it considered ok to do this? Or would you advice against this because these 
"virtual axes" cannot be verified in the field?
