"The Free and Open Source Software for Geospatial Europe (FOSS4GE) conference is the European branch event of the Open Source Geospatial Foundation (OSGeo) annual conference.
OSGeo is the largest and most important international organization that unites the community of developers, users, and advocates of free and open source in geospatial.
The main focus of the organization is fostering the development, maintenance, and use of free and open source software for geospatial, open standards, and open data. "
( Note: I’m not part of the organizing team, but I’ll probably attend as a participant. There are usually OpenStreetMap-related talks too. )
