GeoWiki

Since large differences occur between existing global land cover maps, current ecosystem and land-use science lacks crucial accurate data, which is for example needed to monitor deforestation or determine the potential of additional agricultural land available to grow crops in Sub-Saharan African countries.

GeoWiki is a volunteer community that helps generate and improve land data through different apps based on desk monitoring of land use change or field research. We are currently running the FotoQuest Austria campaign which provides users with an app to verify land cover through photos in the field.

The input provided by users is recorded in a central database and is for the creation of improved global land cover map and datasets that are freely available to any user.
