Abstract

The Geo-Wiki Project is a global network of volunteers who wish to help improve the quality of global land cover maps. Since large differences occur between existing global land cover maps, current ecosystem and land-use science lacks crucial accurate data (e.g. to determine the potential of additional agricultural land available to grow crops in Africa). Volunteers are asked to review hotspot maps of global land cover disagreement and determine, based on what they actually see in Google Earth and their local knowledge, if the land cover maps are correct or incorrect. Their input is recorded in a database, along with uploaded photos, to be used in the future for the creation of a new and improved global land cover map.

It is illustrated how Web 2.0, search and access, functionalities which are part of the EUROGEOSS Discovery broker (e.g. search facilities for geo-referenced FLICKR pictures) can be linked to geo-wiki. Geospatial and temporal resources such as pictures, YouTube videos and additional geo-located social media can help to improve information available to validate current global land cover products. The quality of the information provided by volunteers as well as the quality of social media data in general is discussed.
