[mkgmap-dev] Problem with splitter: Failed to find a correct split

Thu Mar 24 21:03:49 GMT 2016

Gerd,

Yes, alaska.osm.pbf is small.

It works without --no-trim. And it also works with the polygon file that 
belongs to alaska.osm.pbf (also downloaded from Geofabrik) which, 
according to documentation, anyway would disable --no-trim option.

Do you still need the resulting densities-out of the failure ? It's 
about 700 kb... if yes, how should I provide it ? Just attach it here ?

You have to excuse my question, I'm not the crack: is this now a problem 
of the pbf file, or the splitter ? ... or just the way I try to use it ?

Thanks already now for your help.
Patrik
