Citizen science is on the increase. Using their own observations and mobile devices, citizens can provide a new data stream of local information about their environment, complementing existing systems and data sources.
Ground Truth 2.0 is a 3-year EU funded project that is setting up and validating six citizen observatories in real conditions, infour European and two African demonstration cases. The project is demonstrating that such observatories are technologically feasible, can be implemented sustainably and that they have many societal and economic benefits. The ultimate objective is the global market uptake of the concept and the enabling technologies.
