Geo-Wiki provides anyone with the means to actively engage in the monitoring of the Earth's surface by evaluating satellite, drone, or ground-level imagery, while contributing to global environmental research. 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 deforestatio
n 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. 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.
