The annual Geo-Dialog is the exchange platform of the Bonn "Geosphere". Information and dialog on current geoinformation topics are the top priority at this informal evening event. For many participants from science, research, business and administration, the events are a fixed date in the annual calendar.

The events have been held regularly since 2011. Topics have included "Apps - an innovation for the geospatial industry" (2011), "Open data - an opportunity for public administration and business" (2013) and "Smart City Bonn - prerequisites, opportunities, risks" (2015).
