<p class="MsoPlainText"><span lang="EN-GB">Hi</span><span lang="EN-GB"><o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">I did some more testing on using the add-pois-to-lines and mkgmap:from-node: and got a little confused.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">As far as I understand is the classic implementation of add-pois-to-lines to create a poi for every node on the line.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">By checking for example mkgmap:line2poitype = mid you decide to use it or not.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Nice improvement on performance is the mentioned options to not create useless poi's and the idea to do it for start,mid,end,tagged or all<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">The manual states that all values of the line are copied to the node.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">When testing for highway=turning circle it worked even too well as also the node-tags highway = turning_circle was overwritten by the highway = track value of the way it was part of.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Then Gerd started a 'branch' (if that’s the correct word) with the mkgmap:from-node: feature, and also this worked perfectly<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Yesterday I started a new usage: There is a node barrier = gate on a highway = path where the barrier does not have access tags.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">In my style the default for barriers without an access tag is to not allow access (why would they otherwise be added) and highways without access tags to do allow access (that’s where highways for)<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">But as sometimes forgotten by taggers, to finetune access… I'd like to check if the barrier is on a highway with an official bike/hike route as set in the relation file.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">In that case I like to add foot = yes or bicycle = yes. Always worked for the highways but because not set on the barrier-node the routing breaks.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">I expected to be able to catch the barrier with<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Osmid() = 2486838092<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"> Check, catched but no more tags then barrier = gate<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Current implementation r4521<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"> barrier = gate & highway = track & route = foot {echotags 'all'}<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"> but that failed (add-pois-to-lines ~ true)<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Strange because in the turning_circle situations I even got 2 poi's. One for the node and one for being part of a highway.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">My example where routing broke is a barrier = gate somewhere on a highway = track.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">In this case only the osm() node seems to be created and not the "add-pois-to-lines node".<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">On the other hand (strange?) the highway = track does contain the tag: mkgmap:way-has-pois=true to indicate that the highway has barriers<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Finally ...<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Gerd launched the idea to create the tag mkgmap:copied-as-poi=true<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">If there are two pois created "the osm node barrier = gate" and the "add-pois-to-lines node" version, I only can use the "add-pois-to-line version" because that one gives me access to the line where it was derived
from.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">But this also means that when processing the "osm node version" it must be ignored only if later on, another one comes along. How do you know?<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">If a single stand alone barrier comes along, you do like to use it the same way as it is always has be done<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoPlainText"><b><span lang="EN-GB">Questions </span></b><b><span lang="EN-GB" style="font-family:"Segoe UI Emoji",sans-serif">😊</span></b><b><span lang="EN-GB"><o:p></o:p></span></b></p>
<p class="MsoPlainText"><span lang="EN-GB">Can I expect to have the barrier = gate nodes always to created twice if attached to a highway and add-pois-to-line = true?<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Can I catch it with the future functionality we started for the turning circle as well?<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-GB">Do we best extend the mkgmap:copied-as-poi=true to be available both from the osm node version of the poi as well as the created poi?<o:p></o:p></span></p>

<p class="MsoPlainText">while looking at patch addpois-doc.patch I noticed that poi-tagged.patch has a paste+copy error. The new option "tagged" did not work.<o:p></o:p></p>
<p class="MsoPlainText">Attached is a corrected version which implements tagged-node and changes/adds documentation.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">@Mike: Don't know why I used "other" instead of "inner". My bad. We cannot just change the doc, we also have to support the corrected option.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Reg. "creation of POIS from the lines style file" : It might be possible to add new logic which would add a point object while a line is processed. Up to now the order is "relations, points, lines[+polygons], so POIs are processed before
lines. If we change that we have to find an alternative for the dead-end-check processing. Problem : That wouldn't allow to remove the existing code, it just adds complexity with the risk of breaking existing installations.<o:p></o:p></p>
<p class="MsoPlainText">Without the legacy code I would like the idea.<o:p></o:p></p>

<p class="MsoPlainText">Hi Gerd, I've tried out the --add-pois-to-lines=mid option and it seems to work well, giving me something like a 5% performance improvement. There are a couple of errors in the documentation - it doesn't explain what 'other' does, and
there's no option for 'inner' (should 'other' read 'inner' in the option?). Also it says that the default is to create all possible POI - I assume this is the default if the option is provided with no value and that the default is for no POIs to be added.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">You haven't mentioned whether the patch also allows the creation of POIS from the lines style file - I'm assuming it is just the command line.<o:p></o:p></p>

<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I've implemented the suggested improvements with r4507. Please suggest improvements for the documentation changes.<o:p></o:p></p>
<p class="MsoPlainText">I did not yet document the new prefix mkgmap:from-node: in the style because I found no simple description. Feel free to suggest something.<o:p></o:p></p>
<p class="MsoPlainText">Reg. the implementation:<o:p></o:p></p>
<p class="MsoPlainText">I decided to ignore all tags with the prefix mkgmap: , e,g. those from the LocationHook like mkgmap:admin_level2. It might happen that the values for the node are different to those copied from the way, but I don't assume that anybody
wants to add extra rules for that.<o:p></o:p></p>
<p class="MsoPlainText">Maybe I should change it the other way around so that the generated POI gets the "exact" values from the node (without the mkgmap:from-node: prefix?<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The code should also work for POIs added with the --add-pois-to-areas option when the generated POI is using the location of a node because of the --pois-to-areas-placement option.<o:p></o:p></p>

<p class="MsoPlainText">Hi Joris,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">probably my ideas don't work. Your case is very special because you render the POI only when it is part of a way. The example with entrance=main is probably not a good one as entrance=main & is_in(building,mall,on) [...] already works.<o:p></o:p></p>
<p class="MsoPlainText">I've coded a better patch so that your example will also work when option --link-pois-to-ways is not used. Up to now the patch depends on that.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I do not yet see how mkgmap can avoid the generation of all useless POI without adding a lot of code to analyse the rules in the points file, but I still think about this. Problem is that we have the generated tags like mkgmap:admin_level10
or mkgmap:residential and I fear to break something that uses tricky rules with just these tags.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">> Or we could work the other way around, in stead of render all poi's for all objects and not use them, the mapmaker specifies the explicit objects the poi's are needed.<o:p></o:p></p>
<p class="MsoPlainText">Yes, might be an option. An exclude list might also work.<o:p></o:p></p>

<p class="MsoPlainText">Hallo Gerd,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">This works perfect ! (points - file)<o:p></o:p></p>
<p class="MsoPlainText">mkgmap:from-node:highway = turning_circle & highway = track [0x641a resolution 24]<o:p></o:p></p>

<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Your suggestion will indeed also feature your 'entrance=main' example which is actually a very useful one to avoid cluttering The "add-poi-to-lines" option is still usefull I think ?<o:p></o:p></p>
<p class="MsoPlainText">For example<o:p></o:p></p>
<p class="MsoPlainText">- to give a bicycle route a name-poi<o:p></o:p></p>
<p class="MsoPlainText">- render a symbol for the line leisure = slipway<o:p></o:p></p>
<p class="MsoPlainText">- render a cable car symbol for aerialway = gondola<o:p></o:p></p>
<p class="MsoPlainText">- a warning symbol at the highway = via_ferrata<o:p></o:p></p>
<p class="MsoPlainText">- or incline symbols at the start of steep mountain highways?<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">If those could be solved without rendering thousands of poi's for complex multipolygon lines that would be great of course.<o:p></o:p></p>

<p class="MsoPlainText">Hi Joris,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">up to now we only mentioned nodes with a highway=* tag used in ways with a highway=* tag.<o:p></o:p></p>
<p class="MsoPlainText">I've coded a rather simple patch for that, but while I did that I wondered why this should be limited to highways.<o:p></o:p></p>
<p class="MsoPlainText">I decided to use the prefix "mkgmap:from-node:". Tags with prefix mkgmap: are not copied.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">My understanding is that you want a function which tells you if a tagged node is used in one or more ways with a given tag.<o:p></o:p></p>
<p class="MsoPlainText">For example, you may want to render a node with entrance=main, but only when it is the entrance to a building=mall.<o:p></o:p></p>
<p class="MsoPlainText">This will not work, because only nodes with the tags barrier or highway are treated special.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I think it is possible to implement this as well. We probably just have to check the points rules and look for uses of "mkgmap:from-node:".<o:p></o:p></p>
<p class="MsoPlainText">Maybe this would also allow to get rid of the computational overhead produced by the add-poi-to-lines option. The current implementation of this option is really ugly as it computes lots of points which are never used to generate any
map object. Think of a complex natural=wood polygon (no other tags). If the points file doesn't contain a rule for natural=wood there is no need to generate the POIs.<o:p></o:p></p>

<p class="MsoPlainText">For me that would be perfect, the number of cases this will occur is limited so that it's no problem to explicitly test against this replace value. There are probably more situations around highways where this could occur like highway
