| Summary: | The dawn of GeoWeb 2.0, the geographic extension of Web 2.0, has opened new possibilities in terms of online dissemination and
sharing of geospatial contents, thus laying the foundations for a fruitful development of Participatory GIS (PGIS). The purpose of the
study is to investigate the extension of PGIS applications, which are quite mature in the traditional bi-dimensional framework, up to
the third dimension. More in detail, the system should couple a powerful 3D visualization with an increase of public participation by
means of a tool allowing data collecting from mobile devices (e.g. smartphones and tablets). The PGIS application, built using the
open source NASA World Wind virtual globe, is focussed on the cultural and tourism heritage of Como city, located in Northern
Italy. An authentication mechanism was implemented, which allows users to create and manage customized projects through
cartographic mash-ups of Web Map Service (WMS) layers. Saved projects populate a catalogue which is available to the entire
community. Together with historical maps and the current cartography of the city, the system is also able to manage geo-tagged
multimedia data, which come from user field-surveys performed through mobile devices and report POIs (Points Of Interest). Each
logged user can then contribute to POIs characterization by adding textual and multimedia information (e.g. images, audios and
videos) directly on the globe. All in all, the resulting application allows users to create and share contributions as it usually happens
on social platforms, additionally providing a realistic 3D representation enhancing the expressive power of data. |
