<div dir="ltr">Also I don't like using --link-pois-to-ways to put an access=private onto a road - and then remove this road. Because in the case of a park - the footways/pathes on both sides of the gate do exist. So an access=private does not actually apply to the road. So it's correct to show the road, and show the gate that is blocking the road. I think this is better that deleting that road because of the gate.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 10 Oct 2022 at 11:47, Felix Hartmann <<a href="mailto:extremecarver@gmail.com">extremecarver@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hi Gerd,</div><div><br></div>No --<b>add-poi-to-lines</b> creates points from a line that has certain tags.

But as far as I understand right now there is no good solution by mkgmap for this. The same would be for traffic lights - if you remove a road because your map does not show private roads - but a private road has a traffic light - this traffic light should not be in the map either. And yes I know the dilemma - we need points to be looked at pre lines for --link-pois-to-ways to work, but for some other things we would need to look at them later again. So this would need to be some kind of seond_finalize rules in the points file that is executed after the lines file - and removes points from the map again. It's not a big problem - but right now this really makes it inconvenient to put gates into your map - as 75% of gates are just cluttering up the map without providing any information to the user (except if you want to create a cataster type of map showing everything). Leaving gates out completely on the other hand makes it very hard to show for example with parks where people can enter and where not. As very often there are service entries to parks not open to public - so these are the main ones that we want to show in a map.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 10 Oct 2022 at 08:35, Gerd Petermann <<a href="mailto:gpetermann_muenchen@hotmail.com" target="_blank">gpetermann_muenchen@hotmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi Felix,<br>
<br>
my first thought was that --add-poi-to-lines is all that you need, but maybe I've missed something?<br>
<br>
One problem with your suggested solution is that the current implementation in mkgmap processes<br>
(tagged) nodes before lines. I can't remember exactly why but a change probably causes side effects.<br>

Betreff: [mkgmap-dev] Test if POI is part of a line<br>
<br>
I read through the old<br>
poi-tagged-v3.patch<br>
<br>
is_in()function for point on line discussion - but what I want is actually different and should be much easier?<br>
<br>
Could there be a solution to check if a point is a single point vs if it is part of a open/closed line?<br>
Why?<br>
<br>
I would only like to display barrier/highway=gate point icons if they are part of a (best routable) line. Especially for gates most are just useless clutter because they are tagged on private houses and similar.<br>
<br>
If there was a way to delete afterwards/or create only in first place those points that are part of a line would be good, best would be if they are only shown if part of a routable line (so after the lines stye-file is processed).<br>
