I'm currently working on it. Have you tried the patch together with routing? In my trials the routing was completely broken after applying the patch. That is because the merging is done *after* all the routing info is generated. So if two ways are merged into one, the references in the routing part of the map point nowhere. Also the turn restrictions break, because they also refer to the unmerged ways. I'm trying to apply the merging *before* the routing info and the turn restrictions are generated, but up to now I run into all kinds of trouble doing that. I hope I get it working soon, but if you like to work on it as well I can post my current diffs. Regards Thilo Am 12.08.2009 um 17:10 schrieb Clinton Gladstone:

Find attached an patch of my working copy. It is based mainly on my old simplifyWays patch. Its diffed against the current R1102.
The main idea is to merge the lines directly before input them to the filters. It improves drawing speed on my etrex considerably on very low zooms. I'm not sure, if it is the optimal place to do the merging, but it seems to work.
I tested this patch, and it seems to work well. I have not yet thoroughly tested it, and I have not done a speed comparison, but I think the patch is quite worthwhile. Are you considering further work on it, or getting it committed?
Cheers and Thanks. _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
