Geo-Wiki Cropland Validation Campaign

Aim:

The overall objective of the Cropland Validation Campaign is to classify and validate around 40,000 sample areas as to whether they are cropland or not, which will help us improve our baseline map of cropland extent. This layer will form a critical input to the economic land use model, GLOBIOM, which will be used to examine the environmental impacts of agricultural intensification and expansion in the future.

Prizes:

The top 30 participants (ranked by a combination of the highest total score and a final check for quality) will have the option to choose between two main prizes:

• to become a co-author on a scientific paper about our latest and best global cropland map (impact factor > 2.0) or
• to receive an Amazon gift voucher, which will range in value from 50 to 750 EUR, depending upon your position on the final leaderboard. For those that opt for the gift voucher, the highest ranked participant will receive 750 EUR, the second highest 500 EUR, the third 300 EUR, the fourth 100 EUR, the fifth 85 EUR, the sixth 65 EUR, places 7 to 10 will receive 50 EUR and the remaining 25 EUR each. We will ask you to indicate your preference at the start of the competition but you will be able to change your mind at any time.
