OLIVER is MassGIS's OnLIne data ViewER. Written as a stand-alone Java application (and deployed via Java Web Start) it allows you to browse, view, and download (if supported) data from the MassGIS maintained WMS and WFS servers. In short, it is a specific take on a WMS/WFS client.
JOpt.SDK is an automated vehicle routing and dispatching component for both Java/J2SE and .NET. It can solve Travelling Salesman Problems (TSP) and Capacitated Vehicle Routing Problems with Time Windows (CVRP,VRPTW). It offers route and transport optimisation with respect to various constraints such as time windows, load capacities, and prescribed itinerary. The component is based on genetic algorithms, and automatically determines an optimized allocation of vehicels to an arbitrary set of orders.
Mapx is a coordinate transformation library developed at National Snow and Ice Data Center (NSIDC). It was initially developed from equations given by Snyder (1982). Additional projections have been added as needed. The C version currently supports 11 common projections, in both spherical and ellipsoid forms when appropriate. The Java version lags behind somewhat and currently supports nine common projections, in both spherical and ellipsoid forms when appropriate.
