LWKT is a WKT parser under the LGPL license. It have not dependencies: it is pure Java compiled with 1.5 or 1.6 version. The output can be as GML 2 or 3 version, optionally setting a SRS name.
Supported inputs are:

• POINT
• MULTIPOINT
• LINESTRING
• MULTILINESTRING
• POLYGON
• MULTIPOLYGON

For each of them, are handled both 2D inputs like:

POINT(2.4 12.66)

and 3D inputs like:

POINT Z(2.4 12.66 0.0)


At the following URL:

http://95.110.227.201:8080/lwkt

is exposed a minimal web interface in order to test it.

Following, a code snippet as example of usage:

String wkt= "POLYGON ((30 10, 10 20, 20 40, 40 40, 30 10))";

try {
	//To get output as GML version 2:
	String output1 = WKTParser.parseToGML2(wkt);

	//To get output as GML version 3;
	String output2 = WKTParser.parseToGML3(wkt);

	//To get output as GML version 3, setting EPSG:4326 as srs-name;
	String output3 = WKTParser.parseToGML3(wkt, "EPSG:4326");
}
catch(Exception e) {
	e.printStackTrace();
}

To do:

-add the possibility to parse the input as XY(Z) or YX(Z)
