[mkgmap-dev] Splitter question

Try increasing the resolution. The resolution controls the minimum tile
size. Note that increasing the resolution by 1 quadruples the memory use of
one of the internal arrays used to determine split points. I suggest using
13 or 14. Alternatively, you can split the geographic extent of the
too-large tile manually in areas.list.
