Method Detail

snapRoundLines

public static org.locationtech.jts.geom.Geometry snapRoundLines(org.locationtech.jts.geom.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 org.locationtech.jts.geom.Geometry snapRound(org.locationtech.jts.geom.Geometry geomA,
                                                           org.locationtech.jts.geom.Geometry geomB,
                                                           double scaleFactor)
