The Geo-Wiki Project: Validation Competition

The competition has closed!

Owing to the importance of global land cover in disciplines such as climate change, food security and land-use modelling, the creation of a global land cover calibration and validation dataset is essential. To help us achieve this goal, we have established a global sample of validation points which we want you to classify in this competition. You will be presented with pixels overlaid on Google Earth and we would like you to tell us what land cover types you can see up to a maximum of three classes. As most pixels contain multiple land cover types, this will provide us with valuable information for future validation of land cover maps and to get a better understanding on how much people have modified the landscape.

The top 10 classifiers (subject to quality control) will be invited to join as co-authors on a scientific publication called: How much wilderness is there left on this planet? It will be an extension of the work done by Sandersen et al., i.e. The Human Footprint and the Last of the Wild, which you can find here.

Furthermore, the top three classifiers will be awarded Amazon gift certificates with a value of 50 Euro.

The competition will end September 15th, 2012 at 23:59:59 CEST.

Good luck and follow our progress on facebook!
