The annual FOSS4G conference is the largest global gathering focused on open source geospatial software. FOSS4G brings together developers, users, decision-makers and observers from a broad spectrum of organizations and fields of operation. Through six days of workshops, presentations, discussions, and cooperation, FOSS4G participants create effective and relevant geospatial products, standards, and protocols.
FOSS4G has been held all over the world and draws attendees from over 40 countries. Nottingham, England hosted the conference in 2013. In 2014, Portland, Oregon, USA will host FOSS4G’s tenth year.
