[mkgmap-dev] [PATCH v3] - tweeze arc headings to improve routing instructionsFrom Mark Burton markb at ordern.com on Wed Oct 7 10:13:51 BST 2009
v3 - now based on r1265. Added --adjust-turn-headings option to enable this functionality. Reports now downgraded to info (from warn). ------------------------ v2 - various changes - should now work with junctions that have more than 1 side road - should be able to treat exits from roundabouts in the same way as side roads. ------------------------- The attached patch (which also includes the drive-on-left patch because it's based on that) attempts to improve the quality of routing instructions so that when a turn off a road that doesn't involve a big heading change is required, the GPS should say "turn left/right" rather than "keep left/right". It can also reduce the number of "keep left/right" instructions you get when you are not leaving the main road but passing a junction that has a shallow turn (e.g. sometimes happens on motorways when it tells you to keep left/right even though you are not leaving the motorway). I have tested it a little and it appears to work. I expect there are situations where it does the wrong thing so it would be great if people could give it a go and see if it behaves OK. There isn't any option to enable the feature at the moment. If you use the patch, it will be enabled. It's currently issuing a warning for each change it makes but later that can be downgraded to info. Cheers, Mark -------------- next part -------------- A non-text attachment was scrubbed...
