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

Thu Mar 24 21:16:09 GMT 2016

Gerd,

Sorry, your explanations came in during I was writing up the test 
results ...

Think it's all clear so far.

As we're creating lot of different maps I'm just wondering if I 
can/should drop the option --no-trim for all map building or if I would 
suddenly run into other/new problems...

I'll contact geofabrik with the details.

Many thanks and happy Easter.
Patrik
