[PATCH v1] - tweeze arc headings to improve routing instructions
by Mark Burton 04 Oct '09

04 Oct '09

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

Creating DEM-like maps using TYP customisation

Very nice. Has anyone tried this with mkgmap? http://www.cgpsmapper.com/download/Creating%20custom%20types%20to%20represe… What's needed is to simply (?) convert the contour line to polygon. -- cheers, maning ------------------------------------------------------ "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ ------------------------------------------------------

Commit: r1259: Fixed the reading of the label offsets.

Version 1259 was commited by steve on 2009-10-04 11:14:24 +0100 (Sun, 04 Oct 2009) BRANCH: mdr Fixed the reading of the label offsets. 8 bit was consistently wrong, 6 bit was sometime accidentally correct, hence how some streets could be found for 6 bit labels. Searching for streets now works.

Commit: r1258: Read NET so that we can add streets that have their label
by svn commit 04 Oct '09

04 Oct '09

Version 1258 was commited by steve on 2009-10-04 09:33:06 +0100 (Sun, 04 Oct 2009) BRANCH: mdr Read NET so that we can add streets that have their label in NET. This works about 50% of the time for finding streets in files that have LBL format 6 encoding (no --latin1) I think this is because the label offset is read incorrectly.

[PATCH v1] - name motorway exit roads from the exits' names
by Mark Burton 03 Oct '09

03 Oct '09

Annoyingly, motorway exit POIs don't show up on my Nuvi so I thought that the next best thing would be to label the exit roads with the exit name (number). This patch does that in a generic way. It introduces a new facility: If a way (of highway type X) has a POI for its first point and that POI has a tag called X_name, set the way's name to that tag's value. So, if the exit POI (which should be positioned on the first point of the exit ramp) set's motorway_link_name to its name/ref, then the ramp will get that name. So the points style file has something like: highway=motorway_junction & ref=* { add motorway_link_name = '${ref}' name '${ref}' } highway=motorway_junction & name=* { add motorway_link_name = '${name}' name '${name}'} With the patch in place, you need to use the --link-pois-to-ways option for this to work. All feedback appreciated. Mark

Commit: r1257: Add MDR 7 for street names.
by svn commit 03 Oct '09

03 Oct '09

Version 1257 was commited by steve on 2009-10-03 15:04:42 +0100 (Sat, 03 Oct 2009) BRANCH: mdr Add MDR 7 for street names. Does not yet work with routable maps. With non routable, you can see the street names, but cannot find them. Next step will be to make it work when there is a NET section, it might be that it will only work when there is.
