I think the reason why the buildings look different is because, without --order-by-decreasing-area, they get merged into a single area and then a filter (DouglasPeucker), finding the intermediate points are within the tolerance of a straight line, removes all but the 4 corners of the complete block. With --order-by, they are output individually as accurately as possible, but, because we are at/beyond at the limit of accuracy, rounding effects become obvious.
forgot to reply on this. You are right, only it's not DouglasPeucker but RemoveObsoletePointsFilter which removes the nodes at resolution 24. (DP filter is skipped also for shapes at res 24) Gerd -- View this message in context: http://gis.19327.n8.nabble.com/patch-to-write-polygons-in-decreasing-order-t...
