[mkgmap-dev] Bad tile around East London / Greenwich

Sat Aug 7 19:18:06 BST 2021

Hi Minko,

well, yes, the problem is caused by an extreme density of (Garmin) route restrictions. Those are created for OSM turn restrictions and also for barriers when --link-pois-to-ways is used. Maybe this area contains many type=restriction relations with via ways, those require more bytes compared to simple turn restrictions with one via node.
I think the fix in r4805 is the better alternative compared to using --ignore-turn-restrictions.

Gerd

Hi Gerd and Jan,
I have found the difference  that caused this issue for you and not for me:
I have used the parameter ignore-turn-restrictions . Now I can remember I have seen this issue too in a tile in the UK as well, and by adding this it was solved. Does this make sense Gerd?

Mfrgr, Minko

Hi Minko,

I just tried with the latest version of the OFM style and I can still reproduce the problem with r4802.
I adapted he paths in Jans  args and commented only the DEM options.
I can also reproduce it with these few options:
java -jar mkgmap.jar --route --link-pois-to-ways --style-file="d:\git_repos\minko\styles\Openfietsmap full" e:\jan\10700105.osm.pbf

Hi,
I've tried it too with my OFM full style and mkgmap v 4802 but it doesn't show any issues at all.
Maybe some parameters are different? I don't use:
pois-to-areas-placement
poi-excl-index
nearby-poi-rules
