Method Detail

GeoToolsVersion

public static String GeoToolsVersion()

Returns the current GeoTools version.

AsWKT

public static String AsWKT(byte[] wkb)

Returns the Well Known Text of the geometry.

EnvelopeAsText

public static String EnvelopeAsText(byte[] wkb)

Returns the text representation of the envelope of the geometry.

GeomFromText

public static byte[] GeomFromText(String wkt,
                                  int srid)

Reads a geometry from its well known text representation, specifying an srid.

Parameters:

wkt - The well known text of the geometry.

srid - The srid of the geometry

Returns:

An array of bytes representing the geometry.

GeomFromWKB

public static byte[] GeomFromWKB(byte[] wkb)

GetSRID

public static int GetSRID(byte[] wkb)

Returns the spatial reference identifier for the geometry.

This method will return -1 if wkb is null.

Parameters:

wkb - The geometry.

Returns:

The srid.

Envelope

public static Envelope Envelope(byte[] wkb)

Returns the envelope for a geometry.

This method will return an "null" envelope (Envelope.setToNull()) if wkb is null.

Parameters:

wkb - The geometry.

Returns:

The envelope of the geometry.

GeometryType

public static String GeometryType(byte[] wkb)

Returns the type of the geometry as a string. Eg: 'LINESTRING', 'POLYGON', 'MULTIPOINT', etc.

This method returns null when wkb is null.

Parameters:

wkb - The geometry.
