The Geo-Wiki Project is comprised of a global network of volunteers who participate in earth observation driven citizen science

The Geo-Wiki was established in 2009 in what is now known as the Novel Data Ecosystems for Sustainability research group (NODES), located within the Advancing Systems Analysis Program (ASA) at the International Institute for Applied Systems Analysis (IIASA) in Laxenburg, Austria.

An early beta-version was developed in partnership with the University of Freiburg, Germany and the University of Wiener Neustadt, Austria.

The Geo-Wiki platform provides citizens with the means to engage in environmental monitoring of the earth by providing feedback on existing information overlaid on satellite imagery or by contributing entirely new data. Data can be input via the traditional desktop platform or mobile devices, with campaigns and games used to incentivize input. These innovative techniques have been used to successfully integrate citizen-derived data sources with expert and authoritative data.

Since 2009, Geo-Wiki has grown rapidly, with currently over 15,000 registered users and applications in many successful citizen science campaigns, most recently crowdsourcing the drivers of tropical forest loss data, helping to orient environmentally conscious policies.

We have many ongoing projects that bring together the field of Earth Observation and citizen science, including several citizen observatories funded by the EU, which are developing new services such as land cover change detection, quality assurance of citizen science data, supporting local food growers and more.

The Geo-Wiki is a team effort, and has greatly benefited from past members. These include, Antonia Dunwoody, Christopher Dresel, Ben Smith and Christoph Perger. We thank them for their valuable contributions and continued support!
