Commit r3843: Improve throughput and efficiency of ShapeMergeFilter

Version mkgmap-r3843 was committed by gerd on Mon, 13 Mar 2017 Improve throughput and efficiency of ShapeMergeFilter - Much faster for tiles with lots of islands (--precomp-sea) - Finds a few more possible merges http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3843

Hi all, I've noticed that ShapeMergeFilter is still consuming lots of CPU time for some tiles with many islands (using the default style). A single tile in a Finland needed > 21 minutes with r3842, with r3843 it is done in ~ 80 seconds. I've also noticed that it is not useful to call WrongAngleFixer only for merged shapes. Looking at this now. Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von svn commit <svn@mkgmap.org.uk> Gesendet: Montag, 13.
