[mkgmap-dev] Missing addr:place addresses

Mon Dec 3 15:54:15 GMT 2018

Hi Lorenzo,

attached is a small patch to change mkgmap so that it doesn't try to find a name for unnamed roads with road class > 0 or road speed > 2.
It helps for the problem with way 209592070.
Possible problem:  I also see many roads in this area which are tagged as highway=unclassified which probably should be
tagged highway=service or residential, for example way 582373155.
Another problem is e.g. unnamed way 582525015:
- Some numbers close to it have addr:place=Contrada Castelletta
- One has addr:place=Contrada Spirito Santo addr:housenumber=6 (node 5967518378)
Because of the different addr:place names the road gets two labels:
label0 = "", label1=Contrada Castelletta and label2=Contrada Spirito Santo

Now, when I search in MapSource for Number 6 , Street=Contrada Castelletta I find multiple places,
one is the correct one from node 5993083300, the others are wrong. One of the wrong ones
is the above node 5967518378.
The patch doesn't help here, mkgmap has to split those roads instead of adding multiple labels for different
addr:place values.  Needs more work...

Gerd

If I understand correctly I would say yes.
unclassified roads should be tagged with name=* in osm if they have a name and should not take names from nearby roads.

This doesn't happen because of road merging, it is a - normally - wanted result of the housenumber processing.

Maybe I should change the code so that unclassified roads are not treated like service roads here.

It seems to me that road merging in presence of addr:place addresses causes the incorrect propagation of labels to nearby streets.

For example, I see this unnamed road gets the label "Strada Provinciale Potentina".

<https://www.openstreetmap.org/way/209592070>

https://www.openstreetmap.org/way/209592070

This name does not come from an address, it is the name of a nearby street and should not be here.

Hi Lorenzo,

an unnamed service road should solve the problem because the numbers are not assigned to the same road.

Ok Gerd, no worries :)

I guess a service road should also have a name and different from the main road to avoid merging because in my previous example there were already several unnamed roads around the housenumber. Right?

Hi Lorenzo,

I don't see an easy solution for that problem in mkgmap. All I can suggest now is to map a service road where this happens :-(
