GeoServer is a software server that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high performance certified compliant Web Map Service (WMS). GeoServer forms a core component of the Geospatial Web.

Trip Tracker is a position tracking client-server system. It's designed to assist people in setting up a real-time tracking environment with either a private or public tracking server. The Trip Tracker GPS client sends coordinates to the tracking server to update its position. In the event that the GPS client loses its Internet connection, it can send all collected coordinates to the tracking server as soon as it's back online. The tracking server saves all the coordinates and can forward them to listening map clients.
