Method Detail

fromWkt

public static <P extends Position> Geometry<P> fromWkt(String wkt,
                                                       CoordinateReferenceSystem<P> crs)

Decodes the specified WKT String to a Geometry.

This method uses the default WKT dialect (Postgis v1.5 EWKT)

Parameters:

wkt - the WKT string to decode

crs - the Coordinate Reference System for the result

Returns:

The decoded Geometry in the specified reference system

fromWkt

public static Geometry<?> fromWkt(String wkt)

fromWkt

public static <P extends Position> Geometry<P> fromWkt(String wkt,
                                                       CoordinateReferenceSystem<P> crs,
                                                       Wkt.Dialect dialect)

Decodes the specified WKT String to a Geometry.

This method uses the default WKT dialect (Postgis v1.5 EWKT)

Parameters:

wkt - the WKT string to decode*

crs - the Coordinate Reference System for the result

dialect - thw WKT Dialect of the WKT String

Returns:

The decoded Geometry in the specified reference system
