The objectives of the Action, as expressed in the MoU, will be addressed by WGs as follows:

WG1 Societal and human aspects of VGI will take into account MoU objective (3) and establish an open and updatable repository of VGI analysis and integration tools and methods, literature and case studies.
Working group Leaders: Henrik Harder & Kristian Hegner Reinau (reinau@plan.aau.dk)

WG2 Spatial data Quality and infrastructures will address MoU objective (2) and define quality assessment criteria (positioning, ontology, source identification, etc.).
Working group Leader: Vyron Antoniou (v.antoniou@ucl.ac.uk)

WG3 Data mining, semantics and VGI use will deal with MoU objective (1) and develop common data mining software and methodologies that can exploit a wide range of VGI source (such as mapping efforts, photographs, social messaging, etc.) and can be applied in a variety of fields (environment, crisis management, advertising, tourism, etc.).
Working group Leader: Ross Purves (ross.purves@geo.uzh.ch) and Frank Ostermann (f.o.ostermann@utwente.nl)

The three WGs will also address objective MoU (4) and develop cultural and contextual analysis methods of VGI that will help researchers in understanding the local aspects of VGI datasets and their use.
