JTS Topology Suite & GeoTools

Both are java open source tools for spatial data management.

The Open Source Java GIS Toolkit

The JTS Topology Suite is an API of 2D spatial predicates and functions. It has the following design goals:

* JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium
* JTS provides a complete, consistent, robust implementation of fundamental 2D spatial algorithms
* JTS is fast enough for production use
* JTS is written in 100% pure JavaTM
* JTS is open source (under the LGPL license)

Find more information, you can find it from here.


Geo Tools is an open source (LGPL) Java code library which provides standards compliant methods for the manipulation of geospatial data, for example to implement Geographic Information Systems (GIS) . The Geo Tools library implements Open Geospatial Consortium (OGC) specifications as they are developed, in close collaboration with the GeoAPI and GeoWidgets projects. The capabilities of Geotools are presented in the feature list.
