[mkgmap-dev] Commit: r881: Add option to frig roundabouts.From svn commit svn at mkgmap.org.uk on Fri Feb 13 20:00:00 GMT 2009
Version 881 was commited by robert on 2009-02-13 20:00:00 +0000 (Fri, 13 Feb 2009) Add option to frig roundabouts. Add option to "frig" roundabouts by adding an extra point between each pair of adjacent nodes. The extra points are positioned "outside" of the line joining the two nodes. The effect is to make roundabouts "rounder". Unfortunately, it also makes them ugly as the frigging is being done by a dumb computer with little aesthetic capability. It is not enabled by default, you need to specify the --frig-roundabouts option. By default the "frig factor" (influences how far the new points are away from the centre of the roundabout) is set to 0.25. You can specify a different value as the option value: --frig-roundabouts=0.1 Large values tend to make the roundabout uglier so it would be worth experimenting to see what the minimum frig factor is that will stop the gps from reporting the wrong exit. You can also enable frigging for an individual roundabout by tagging the OSM XML with the "mkgmap:frig_roundabout" tag which can either be set to a valid (floating point) number to specify the frig factor or just some other string that will make it use the default frig factor. This patch also avoids putting in new points if the new point would be less than 5 or more than 100 metres from the adjacent points. - Mark Burton
