The JTS Topology Suite is an API for modelling and manipulating 2-dimensional linear geometry. It provides numerous geometric predicates and functions. JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium.

...Now in 0.3.0: osm_tags: tag analyzer (like tag watch) osm_split: split osm file in single files for nodes, ways and relations and collect some meta information (will be used as input for other tools). osm_cut: create rectangular extracts tr_view: view tool for trafalgar files, including fast osmtoolz import filter, GPX an KML track import (see screenshots) There is a small script included which helps to transform from *.bz2 to *.gz using a named pipe (seems not to work for cygwin)

polyclip is a free library for fast clipping of polygons, written in C++. It supports arbitrarily shaped polygons, including multi-part,self-intersecting and holed polygons. Degenerate cases such as touching and overlapping polygons are also handled. polyclip is Free Software, available under the GNU LGPL license.

Open Source Routing Machine computes shortest paths in a graph. It was designed to run well with map data from the Openstreetmap Project.

Graphserver provides fast shortest-path computations on very large graphs, for use as a sub-component of a trip-planning service.

Java and ColdFusion libraries to lookup country code and language from IP address. It uses a local copy of the WHOIS database to perform fast, accurate lookups of country codes. Useful for log analysis, internationalization, geolocation, etc..

This project aims to produce a fast and reliable Java library for converting JTS (Java Topology Suite) Geometry Objects into OGC GML-conformant DOM Elements

2D, 3D object indexes (Quadtree, Octree, Quadtree with object radius indexation), fast geometry find functions, template classes with embedded 2D, 3D indexation and fast search features.

Mobilemaps is a Nearby Engine which allows users to find Web pages by location. Extremely fast and capable of scaling to any number of pages, it supports OpenGIS map-servers and uses MySQL, Perl and C.

...While there are other open-source GIS, and image-processing packages available, this one is designed to be comprehensive, work on 3 major platforms, user-extensible, fast, and able to handle huge datasets. Click the Blog tab for more info.
