Method Detail

validateGeometry

public org.locationtech.jts.geom.Geometry validateGeometry(org.locationtech.jts.geom.Geometry geom)

Validates the given polygon-based geometry. Tries to simplify the geometry. Simplification is used for multipolygon elimination. This is much experimental, use it at your own risk.

Parameters:

geom - -- polygon-based geometry

Returns:

bufferValidate

public static org.locationtech.jts.geom.Geometry bufferValidate(org.locationtech.jts.geom.Geometry geom)

Validate given geometry using buffer(0.0) trick

Parameters:

geom -

Returns:

simplifierValidate

public org.locationtech.jts.geom.Geometry simplifierValidate(org.locationtech.jts.geom.Geometry geom)

Validate the given polygon-based geometry using D-P simplifier setEnsureValid is set to true

Parameters:

geom -

Returns:

polygonizerValidate

public static org.locationtech.jts.geom.Geometry polygonizerValidate(org.locationtech.jts.geom.Geometry geom)

Get / create a valid version of the geometry given. If the geometry is a polygon or multi polygon, self intersections / inconsistencies are fixed. Otherwise the geometry is returned.

Parameters:

geom -

Returns:

a geometry
