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

Sun May 31 08:06:11 BST 2020

Hi Gerd

Thanks for the answer, always nice if it makes sense again. Then it was worth the testing 😊
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 = bus_stop, highway = speedcamera, and traffic signals.

Kind regards,
Joris

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.
