In other words, the old and the new way will never be more than e.g. 3 m apart. The tool uses the [https://en.wikipedia.org/wiki/Ramer–Douglas–Peucker_algorithm Ramer–Douglas–Peucker algorithm] for way simplification, but makes sure that tagged nodes and nodes with more than one parent way are not deleted. [[Image(Simplify_way.png,link=)]] == See also == * [[Image(/pluginicon/SimplifyArea.jar/images/preferences/simplifyArea.png,24,link=,middle)]] SimplifyArea plugin - despite the name, also simplifies ways. Uses a different algorithm and has more parameters for tuning. In particular for nodes A, B, C the node B is not deleted unless * area of the triangle ABC is lower than 5 m^2 * distance of B to the line AC is lower than 3 m * angle ABC doesn't deviate more than 10° from 180° * [[JOSMImage(distribute)]] [wikitr:/Help/Action/DistributeNodes Distribute Nodes] ---- Back to [wikitr:/Help/Menu/Tools Menu Tools] \\ Back to [wikitr:/Help/Menu Main Menu] \\ Back to [wikitr:/Help Main Help]
