Thus, this paper fits in this heterogeneous context with the goal
of analyzing public participation in GIS in the field of sensorenabled
mobile devices. The main objective driving the study is
to supply a GeoWeb 2.0 system for potential use by a number of
entities and organizations (ranging from public authorities to citizen
associations) able to manage general-purpose data-collection
campaigns addressing the public. This is achieved through the
development of an open source software architecture that is then
applied to a number of case studies. Their outcomes make it possible
to derive some general observations on public participation
patterns in contributing VGI.
