Every year after the Flächennutzungssymposium, experts are invited to take part in a closed workshop to discuss topics such as requirements for time series, basic datasets, their development and new indicators. Participants are providers of basic geodata (AdV, LVAs), statistical data (Destatis, Stala), agencies involved in policymaking (BMUB, BBSR, UBA, SMI, SMUL) as well as scientific institutes (BBSR, IOER).
