Answers to: JOSM: Simplify way - simplify-way.max-error parameter meaninghttps://help.openstreetmap.org/questions/10541/josm-simplify-way-simplify-waymax-error-parameter-meaning<p>What does exactly simplify-way.max-error parameter mean? I found in a discussion from 2009 it was supposed to be mean an error counted in meters (m). But the function seems to run pretty high even with a parameter smaller than 1. I used 0.25 and it seemed to me the error was still counted in several meters... cound not find a real clue here myself.</p>enSun, 26 Feb 2012 13:05:34 +0000Comment by Kozuch on bastik's answerhttps://help.openstreetmap.org/questions/10541/josm-simplify-way-simplify-waymax-error-parameter-meaning#10811<p>Please stay calm, I am not touching data of others.

<p>Application of this function has to be considered a <strong>kind of automated edit</strong> and is therefor subject to the special rules we have for this kind of edits.</p>
