Welcome to the JTS-Algorithm-Pack wiki!

JTS Algorithm Pack (JAP) is a Java library and command line utility, that extends JTS Topology Suite (JTS) with novel new algorithms like Concave Hull. You can download a demo here: jap.zip (README included)

Algorithms in JAP take a JTS geometry as input like this point cloud:

And runs an algorithm that produces another JTS Geometry as output, like this Concave Hull:

The command line utility works with WKT tekst as input/output. See jap.zip for example.
