With the 1st strategy it could happen that you have 87 tiles with a 99% fill ratio and 2 with < 50%. The algo also stops if the worst fill ratio is 93% or higher.

Hi Gerd, splitter version 392 is even better, it splat Germany.o5m to only 90 tiles! :) Best regards, Uli -- View this message in context: http://gis.19327.n5.nabble.com/Patch-v1-improve-splitter-tp5807051p5807253.html Sent from the Mkgmap Development mailing list archive at Nabble.com. ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] [Patch v1] improve splitter
Hi Uli, yes, in most cases the patched version is much better, and I have found some nice improvements so I have an even better patch, BUT it is not very good when splitting a whole planet. I still try to understand why the old version is able to find a rather usable split with only a few tests, while the patched version is running much longer to end up with a bad result.

Hi Gerd, i splat ( ;-) ) Germany.o5m with --max-nodes=200 per tile. With version 389 i get 96 tiles, with the improved version i get only 91 tiles with extraordinary equality in size, also the final gmapsupp.img is smaller. I think, it's a good improvement!

Hi Bernd, thanks for the feedback and the data. I am working on some more improvements for large inputs or those that contain large empty areas.

I've made some tests with the patched version, you find my logs here: http://files.mkgmap.org.uk/download/209/splitter.zip For me, it's seems to be a great improvement Bernd ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
