[mkgmap-dev] [PATCH v1] - tweeze arc headings to improve routing instructionsFrom Mark Burton markb at ordern.com on Sun Oct 4 11:26:52 BST 2009
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...
