Abstract

The concept of crowdsourcing is to collect and share information from 'the crowd'. The diffusion of smartphones and tablets led to what can be pictured as a 'dense network of observers' that can be used to submit useful data possibly complementing satellite-based Earth observation. In this paper, we propose a multi-purpose framework specifically designed to collect data in a distributed way; the model is based on a client-server architecture and an open-source framework including PHP and SQL. Communication among the devices is guaranteed by standard protocols like HTTP and JSON. An example of application based on this framework is also presented; the main objective is to collect information about water quality by asking users to provide feedback. The interface is both web- and mobile-based.
