✔ Evolution of the 1990s GeoWeb 1.0
✔ Interactive tools allowing user participation in spatial data management
✔ OGC standards for geospatial interoperability
✔ GPS, AJAX and mapping Application Programming Interfaces (APIs)
✔ Neogeography (Turner 2006)
GeoWeb 2.0
Geomatics Laboratory, Politecnico di Milano – Como Campus
➔ creation of maps through mash-ups of multiple data sources
➔ the act of a mass of users to share a job through an open call
➔ the idea of humans acting as sensors able to acquire spatial contents
➔ users can easily perform real-time collection of georeferenced data
✔ Diffusion of mobile devices equipped with sensors (GPS, camera, etc.)
✔ Volunteered Geographic Information (VGI) (Goodchild 2007)
✔ Crowdsourcing (Howe 2006)

✔ Set of practices in which citizens participate in data collection, analysis
and dissemination of a scientific project
✔ Active or passive
✔ Explicit or implicit
✔ Classification
Citizen science
Geomatics Laboratory, Politecnico di Milano – Como Campus
➔ 'classic' citizen science: citizens engaged in traditional scientific activities➔ community science: measurements and analysis carried out by amateurs
in order to set action plans to deal with environmental problems➔ citizen cyberscience: use of computers, GPS receivers and mobile phones
✗ volunteered computing: citizens download data, run analyses on
their own computers and send back data to the server✗ volunteered thinking: citizens perform classification works✗ participatory sensing: applications centered on mobile phones

➔ mobile device field-data collection of water-related phenomena and points of interest
➔ data access and interaction based on user privileges➔ data Web publication and sharing➔ data access through multi-dimensional (2D and 3D) Web interfaces
✔ To build an architecture for a citizen science application focused on water management, which enables:
Purpose of the work
Geomatics Laboratory, Politecnico di Milano – Como Campus
✔ To use FOSS (Free and Open Source Software), i.e. programs which recognize users four essential freedoms:
➔ to run the software for any purpose➔ to modify the software according to the needs➔ to re-distribute copies of the software➔ to distribute copies of modified versions of the software
12
➔ IT support to research and teaching activities➔ positioning, surveying, Earth observation & gravimetry➔ photogrammetry, remote sensing, DTM analysis➔ cartography, GIS, Internet GIS
✔ Geomatics Laboratory, Politecnico di Milano – Como Campus
Project partners
Geomatics Laboratory, Politecnico di Milano – Como Campus
✔ Po River Basin Authority (Autorità di bacino del Po – AdbPo)
➔ mixed institution (involves the State, the administrative regions and many institutional bodies concerned with Po river management)
➔ responsible for planning and protecting the basin of river Po
✗ longest Italian river (652 km)
✗ largest Italian hydrographic basin ( ~ 74000 km2)
✗ highly-heterogeneous territory with complex environmental issues

Conclusions and future outcomes
Geomatics Laboratory, Politecnico di Milano – Como Campus
✔ FOSS architecture for a water management citizen science application
➔ from mobile device data collection to Web visualization and sharing➔ born from the need of enlarging AdbPo consciousness of its basin through
the collection and valorisation of user local knowledge and experience➔ project still at its early stage➔ app tested by technicians of AdbPo and other water-related agencies
✔ Future improvements
➔ exploitation of the Enketo Web framework to allow form compilation even from computers [almost done]
➔ improvement of the Web viewer (in both graphics & functionalities)
➔ involvement of the general public in testing and using the application
➔ [hopefully in the long run] evolution of the system into a fully-equipped platform able to manage water-related emergencies
