The Open Bioinformatics Foundation or O|B|F is a non profit, volunteer run organization focused on supporting open source programming in bioinformatics.

Artemis database entries or sequence in FASTA or raw format. Extra sequence features can be in EMBL, GENBANK or is a free genome viewer and annotation tool that allows visualization of sequence features and the results of analyses within the context of the sequence, and its six-frame translation. Artemis is written in Java, and is available for UNIX, GNU/Linux, BSD, Macintosh and MS Windows systems. It can read complete EMBL and GENBANKGFF format.

PyMOL is a USER-SPONSORED molecular visualization system on an OPEN-SOURCE foundation.

RasMol is a program for molecular graphics visualisation.

Bioconductor is an open source and open development software project for the analysis and comprehension of genomic data.

GRASS GIS (Geographic Resources Analysis Support System) is an open source, free software (FOSS) Geographical Information System (GIS) with raster, topological vector, image processing, and visualization functionality

The Unified Mapping Platform (JUMP) is a GUI-based application for viewing and processing spatial data.  It includes many common spatial and GIS functions.  It is also designed to be a highly extensible framework for developing and running custom spatial data processing applications.

gpsfeed+ is a utility that feeds the PC with continuous GPS data as if a GPS were moving in a car or airplane. NMEA 0183 GPS sentences are sent to the application through a socket (TCP/IP) connection or a UDP multicast message. It also outputs the same NMEA data to a serial port of the PC. Polling applications can query the embedded lightweight http server to obtain gps data either in text form or as an XML data snippet. The IP connection offers significant advantages over a serial port connection:

• many applications can connect to one single gps simultaneously
• remote gps' can be monitored
• Serial ports can be freed for other uses. In most cases, the only readily available and simple I/O interface is the RS232 connector.
• and, of course, testing can be done indoors, without any GPS hardware or cabling

The "Open GPS Tracking System" (OpenGTS™) is the first available open source project designed specifically to provide web-based GPS tracking services for a "fleet" of vehicles.
