[mkgmap-dev] splitter r440 released

Wed Nov 16 11:31:36 GMT 2016

Hi all,

I've fixed a major bug in splitter which results in wrong output files when
you pass a --split-file which contains
overlapping areas. See also 
http://www.mkgmap.org.uk/websvn/revision.php?repname=splitter&rev=440

Splitter doesn't generate such a file, but one can create such a file in an
editor (intended or accidentially)

I am not sure what happens when you create a gmapsupp with overlapping
tiles, I'd expect problems with routing at the tile boundaries. So, I think
splitter should stop when overlaps between tiles with the same mapid prefix
are found, e.g. overlapping tiles 63240010 and 63240013 are not allowed,
while
overlapping tiles 12340001 and 43210001 would be considered okay.
I've not yet implemented this test, what do you think about it?

Gerd
