Hi Gert, yes, I think it must be useful, I also see it in Minkos styles at http://www.openfietsmap.nl/ I don't fully understand the "better than nothing" part . The current code adds a POI to each point, so each point has a mkgmap:line2poitype=* tag with values start,end,mid, or inner for the rest. The option should be handled with great care, it is likely to produce a large number of POI for highly detailed ways created by some imports. I already thought about an addtional parameter for the option, something like --add-pois-to-lines=n where n gives a value in meter for the minimum distance between two generated POI when the way has more than 3 points.

If I got you right, you would like to specify something like --add-pois-to-lines=tag1,tag2,tag3,...,tagn and mkgmap should then create POI for all lines having at least one of the tags, and those POI would not have any other than the listed tags (besides the mkgmap:line2poi tag and those from the boundaries) ?

Hi Gerd, at the moment if you add the option add-pois-to-lines the code will add all pois to all lines. In many cases this does not matter, because line tags are not used very often in points file, but if they are used, you have to delete these added POIs if you do not want them to be shown. I have given some examples of what I am deleting, but this would depend on your points file. If it would be possible to say --add-pois-to-lines=aerialway and only aerialway pois are generated, this would be super plus perfect, but I’m also happy with the existing solution. The only disadvantage of the existing solution is, that you should not forget the delete the not used pois, otherwise some lines would look really ugly.

Hi Gerd, a closed loop is an interesting example. I don’t know, what mkgmap:line2poitype=mid would do here. At the moment I would expect to get additional POIs with all 4 tags aerialway, leisure, name, sport If I do not need leisure and sport, I would delete them, so the POIs would only keep aerialway + name. With --add-pois-to-lines=aerialway,name I would expect the same result like after the deletion.

Hi Walter, sorry, did not notice that the way is a polygon, but you probably got me right anyway. On the other hand, I still don't see how the parameters would work . Assume you want to create POI for aerialway=* and aeroway=* and maybe more. I assume you would always have to add the delete rules to make sure that you get what you want, so the only advantage that I see is that we might save a few bytes and cpu cycles when we interpret the parameters so that ways are ignored if none of the given tags are found.

Hi Gerd, I think you are right. The advantage of such an extra parameter might be very little. When I first started with this option, I’d expected having to delete a lot of not needed parameters. But when I got more experience I noticed, that most of the generated POI are ignored by default and need no extra deletion rule.
