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 global agricultural field-size data, performing post-disaster damage assessment, poverty mapping and more. 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.
