The OSGeo Foundation is community driven and has an organizational structure consisting of elected members and nine directors, including the president. Software projects have their own governance structure, by requirement. see FAQ.  The OSGeo community collaborates via a Wiki, Mailing Lists and IRC.

OSGeo projects include:

Geospatial Libraries 

 FDO – API (C++, .Net) between GIS application and sources; for manipulating, defining and analyzing geospatial data.
 GDAL/OGR – Library between GIS application and sources; for reading and writing raster geospatial data formats (GDAL) and simple features vector data (OGR).
 GeoTools – Open source GIS toolkit (Java); to enable the creation of interactive geographic visualization clients.
 GEOS – A C++ port of the Java Topology Suite (JTS), a geometry model.
 MetaCRS – Projections and coordinate system technologies, including PROJ.
 Orfeo ToolBox (OTB) – Open source tools to process satellite images and extract information.
 OSSIM Extensive geospatial image processing libraries with support for satellite and aerial sensors and common image formats.
 PostGIS – Spatial extensions for the PostgreSQL database, enabling geospatial queries.

Web Mapping

Server 

 MapServer – Fast web mapping engine for publishing spatial data and services on the web; written in C.
 Geomajas – Development software for web-based and cloud based GIS applications.
 GeoServer – Allows users to share and edit geospatial data. Written in Java using GeoTools.
 deegree – Java framework
 PyWPS – implementation of the OGC Web Processing Service standard, using Python

 GeoMoose – JavaScript Framework for displaying distributed GIS data.
 Mapbender – Framework to display, overlay, edit and manage distributed Web Map Services using PHP and JavaScript.
 MapGuide Open Source – Platform for developing and deploying web mapping applications and geospatial web services. Windows-based, native file format.
 MapFish – Framework for building rich web-mapping applications based on the Pylons Python web framework.
 OpenLayers – AJAX library (API) for accessing geographic data layers of all kinds.

OSGeo runs an annual international conference called FOSS4G – Free and Open Source Software for Geospatial.  Starting as early as 2006, this event has drawn over 1100 attendees (2017 Boston) and the tendency is to increase this number every year.  It is the main meeting place and educational outreach opportunity for OSGeo members, supporters and newcomers - to share and learn from one another in presentations, hands-on workshops and a conference exhibition.  The FOSS4G ribbon, part of every FOSS4G event logo, symbolizes the flow of ideas, innovation, and sharing within the Open Source geospatial community.  The event history dates back to an important face-to-face meeting of the 3 original founders of the event (Venkatesh Raghavan, Markus Neteler, and Jeff McKenna), who met initially in Bangkok Thailand in 2004, and planned to create a new annual event for the whole Open Source geospatial community, with the event named "FOSS4G"; the event would go on to help change the history of the geospatial industry.
