Citizen observatories are sets of ICT-tools to collect, analyse and visualise sensor data, with the aim of improving the quality of life of citizens. Participatory sensing is the driving technology behind citizen observatories. It allows people-centric contextual monitoring by way of smart mobile devices.

Citizen observatories are sets of ICT-tools to collect, analyse and visualise sensor data, with the aim of improving the quality of life of citizens.

Today citizen observatories have to be developed from scratch for each application area, an enormous effort as witnessed by dedicated consortia for the topics of air quality, water quality, ocean monitoring and odour monitor- ing, under the 2012 EU-ENV-FP7 call. These first-generation citizen observatories prove the critical role of ICT in the evolution towards a sustainable society, but deploying a new citizen observatory remains extremely difficult and labour-intensive. Despite an overwhelming demand for such platforms, they are thus beyond the reach of most societal stakeholders. This is the gap we aim to close through the FLAMENCO project.
