[mkgmap-dev] is_in() function for point on line

Sat May 30 17:38:56 BST 2020

Hi Joris,
yes, it is a special case. The generated POI gets the tags from the way, so highway=turning_circle is replaced by highway=track.
The node 7131748927 appears only with the tag highway=turning_circle (and maybe the address tags)

Not sure what to do. Maybe store the replaced tag(s) with a prefix, e.g. mkgmap:replaced:highway=turning_circle in this case?

Hi Gerd

Could it be possible that in this case the highway tag of the line is ignored because the point turning_circle is of type highway as well?

It's like there is a point {highway = turning_circle} on a line {highway =  track}
It looks like I cannot catch it with the mkgmap:line2poitype and mkgmap:line2poi.

Somewhere else I already use
leisure = slipway & mkgmap:area2poi != true & mkgmap:line2poitype = mid  and that works fine

Kind regards,
Joris

Hi Joris,

is_in() only works with polygons. You can use --add-pois-to-lines, but be aware that it produces a lot of points for which you probablly don't want to add an object to the map. See the help for the details.

Hi

Does the is_in() function should also work for a point on a line in stead of in a polygon?

highway = turning_circle & is_in(highway, track, in_or_on) = true      [0x641a resolution 24]

It returns false for this situation where the turningcircle is attached to a highway = track.
(mkgmap:cache_is_in_POINT_highway_track_in_or_on=false)

Would there be another way to know if the point is attached to a highway = track rather then a for example highway = residential?
I use add-pois-to-lines, and link-pois-to-ways but as far as I can see, that doesn't give me more information.
