Hi Minko, if you can't find any, that is also telling me that the option is rather useless. With --cycle-map mkgmap might produce larger changes when the sum of the road_speed values of two arcs is rather high. The corresponding part of the patch: + if (cycleMap){ +// if (sumSpeeds >= 14) +// maskedMinAngle = 0x80; +// if (sumSpeeds >= 12) +// maskedMinAngle = 0x70; +// if (sumSpeeds >= 10) +// maskedMinAngle = 0x60; + if (sumSpeeds >= 8) + maskedMinAngle = 0x50; + else if (sumSpeeds >= 6) + maskedMinAngle = 0x40; + else if (sumSpeeds >= 4) + maskedMinAngle = 0x30; + } Does that help?
