They are ignored for resolution 24, in which the WrongAngleFixer is used to guess how an object can be placed on the Garmin raster so that it looks as much as possible like the OSM described by the OSM data. If you want to play with that: The WrongAngleFixer has a few constants, e.g. you may increase the value MAX_DIFF_ANGLE_STRAIGHT_LINE = 3; or change the method calcMaxErrorDistance() to allow larger errors.

I have a similar issue with the way polygons display on my Garmin device. What appears as a smooth curve on the OSM slippy map are very blocky on the device. I have played with the reduce-point-density=4 and reduce-point-density-polygon=8 parameters in an attempt to smooth those curves but they seem to have no effect. I can live with the distortion but I wonder, what do these two parameters actually control?

One can't draw precisely a line, which length is near to this resolution. You can try to assign the same Garmin object type to all these segments, then probably mkgmap will be able to merge them and smooth. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev -- Dave Swarthout Homer, Alaska Chiang Mai, Thailand Travel Blog at http://dswarthout.blogspot.com _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
