Hi, unfortunately --no-trim has not helped, i can still observe such gaps.

The splitter command:
java -Xmx1200m -jar ../mkgmap/splitter-r597/splitter.jar \
--output-dir=norden/splitted/ \
--mapid=77700001 \
--max-nodes=1500000 \
--no-trim \
norden/norden.o5m > norden/splitted/splitter.log

Kind regards
Karl
