If you use the option reduce-point-density then the line is straightened using the douglas peucker algorithm. All segments between two endpoints or T-crossings are straightened. The points of crossings are not touched. Find a description of the algorithm at wikipedia. http://de.wikipedia.org/wiki/Douglas-Peucker-Algorithmus Regards, Johann Minko schrieb:
On the dutch osm forum this particular roundabout has raised some questions about how mkgmap deals with filtering those nodes. Does it calculate an avarage position of a cluster of nodes that are (too) close to each other and group them into one node? Is this the reason why those jagged lines show up on the garmin img? _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev .
