IIRC EnhancedPrecisionOp uses CommonBitsRemover. The BinaryOp tries with original precision first, then tries with CommonBitsRemover then tries with SNapping ie: it applies different heuristics struggling to give some meaningful result. Compare EnhancedPrecisionOp with BinaryOp ---strk; _______________________________________________ geos-devel mailing list geos-devel@geos.refractions.net http://geos.refractions.net/mailman/listinfo/geos-devel
