[mkgmap-dev] gmappsupp size with 20% bigger when using latest splitter

Thu Oct 23 07:29:55 BST 2014

Hi Enrico,

splitter r412 should produce fewer tiles, so one explanation might be that the last for 
tiles were not produced by r412. Since your listing shows different timestamps for them
I'd say you did not start with a clean directory.

I updated my splitter version from 314 to 412 - now, it's pretty late but I read about the new split algorithm that might cause some different sizes than before,  maybe I searched too quickly but I can't seem to explain why the final gmapsupp went from  87MB  to 107MB.

Looking at the split output in 412 and 314, it's clear 412 creates bigger files. Strange enough the last 4 files have the same size...

Does this sound right to you?
