Crowdsourcing Data Collection

“Volunteer sensing” involves participants collecting data relevant to solving a specific challenge. People equipped with cellphones or other low-cost digital sensors can monitor and report on many aspects of their environment. Projects in fields as diverse as biodiversity tracking or pollution mapping can benefit from the help of citizens actively collecting data in the form of photos or other measurements.


Project Noah is a tool to explore and document wildlife and a platform to for citizen scientists everywhere. The community is harnessing the power and popularity of new mobile technologies to collect important ecological data and help preserve global biodiversity.

Safecity is a platform that crowdsources personal stories of sexual harassment and abuse in public spaces. This data which maybe anonymous, gets aggregated as hot spots on a map indicating trends at a local level.

The project aims to mobilise citizen sailors, known as ‘Planktonauts,’ to provide continuous samples of plankton from all over the world to biological oceanographers. By combining this dynamic biological information with new models of the ocean’s systems, scientists will be able to better predict changes to our planet.

Lichens are sensitive to air pollution, and their presence or absence can be used to monitor the quality of the air. This project wants to analyze, classify and measure the size of the lichens in order to study the quality of air in cities.
