Geo-Wiki is a platform for engaging citizens and experts in both environmental and socioeconomic monitoring, established in 2009 at the International Institute for Applied Systems Analysis (IIASA). It aids in both, the validation of existing geographical information and the collection of new geographical information through crowdsourcing[1][2] and citizen science.[3] Using data sources such as satellite imagery, geotagged photographs and the Internet, individual volunteers are able to contribute valuable in-situ data, either by validating existing data and comparing it with satellite imagery (through visual interpretation), or by collecting new information. Other methods for crowd-sourced data collection in Geo-Wiki include campaigns and games, used as incentives to motivate citizens. Collected data in the platform is freely available.
By 2020, Geo-Wiki had more than 15 000 registered contributors, and many successful citizen science campaigns, collecting data on topics such as global built-up surface validation, human impact on forests,[4] global agricultural field-size data[5] and more.
