Method Detail

snapRoundLines

public static Geometry snapRoundLines(Geometry geom,
                                      double scaleFactor)

Reduces precision pointwise, then snap-rounds. Note that output set may not contain non-unique linework (and thus cannot be used as input to Polygonizer directly). UnaryUnion is one way to make the linework unique.

Parameters:

geom - a geometry containing linework to node

scaleFactor - the precision model scale factor to use

Returns:

the noded, snap-rounded linework

snapRound

public static Geometry snapRound(Geometry geomA,
                                 Geometry geomB,
                                 double scaleFactor)
