FOSS4G 2027
Global open source geospatial software conference
About this event
FOSS4G is the global conference for Free and Open Source Software for Geospatial, hosted in partnership with OSGeo. The 2027 edition returns to Europe, held at the University of Bristol and organised by OSGeo:UK, with two days of hands-on workshops followed by three days of conference sessions covering open source GIS tools including QGIS, GRASS and GDAL.
Who it's for
Useful for developers, analysts and researchers who build with or contribute to open source geospatial software such as QGIS, GDAL, PostGIS and GRASS. Relevant to public sector, academic and commercial teams adopting open source GIS, and to decision makers weighing open source options. Not aimed at those committed to a single proprietary GIS stack with no open source interest.
