[mkgmap-dev] internal error: found no housenumber road

Sat Feb 27 20:52:30 GMT 2021

Hi Joris,

reg. house numbers on footway:  If you don't want them you can add a rule like this
highway=footway {add mkgmap:numbers=false}

Hi Gerd,

If I understand correctly...
For me searching the roadname really matching the addr:streetname would make the most sense even if it is not the closest way.
The closest way could be divided from the address by a 'river' or 'fence/hedge/barrier' anyway?

As far as i understand it only happens in odd situations. So using the first highway segment that matches the name is a solution to me.

Kind regards
Joris

Met vriendelijke groeten,

Hi all,

I've uploaded a file with the problematic area: http://files.mkgmap.org.uk/detail/501
I see no obvious error in the housenumber data, all looks plausible, only some building=yes tags on nodes are probably wrong, but that isn't a problem here.

I really wonder what result I want to get from this data. There are two addr:interpolation=odd ways along the footway https://www.openstreetmap.org/way/775843679, so I think mkgmap should produce data so that the address for e.g. the node https://www.openstreetmap.org/node/1025525702
addr:housenumber=477
addr:street=Royal Parade
is found on that footway, as well as the interpolated numbers 459 ... 477 and many more numbers which belong to "Royal Parade", even though the footway has no name and is not connected to "Royal Parade" but to "Ievers Street".

The alternative would be to use https://www.openstreetmap.org/way/573320541 as it has the right name, but it is not as close. All the other highways named "Royal Parade" should be dismissed (which isn't easy to compute) because way 573320541 is also split into fragments because of the --link-pois-to-ways processing.

So, as so often with house numbers we have a lot of correct information and the heuristic in mkgmap should find out that footway belongs to "Royal Parade", but that doesn't work. The "internal error" is produced because node 1025525702 appears in two addr:interpolation intervals. The program tries to find a single road to use for the interpolation and that goes wrong here. The details are too complex to explain here. In short the data is "corrected" too often.

The failing code exists to avoid cases were a single, obviously wrong addr:interpolation way would generate lots of wrong address nodes. IIRC  I added it to detect nonsense in the imports of Canvec data (Canada). I have to find out if this code is still needed and if yes, how to improve the heuristic to avoid the internal error.

Hi Carlos,

yes, it requires the footway, probably also other roads and a special order in the addr:interpolation way and maybe more. I found a possible fix but I need more time to understand in what case this will cause problems.
The map is usable, a few house numbers may not be found.

Gerd

Thanks for investigating it. I've been using those two rules for several years, it's strange the problem didn't arise till now.
