Join our new campaign to contribute to science and win prizes!
We are excited to announce the start of a new campaign to help us validate a global built-up surface layer produced by the Joint Research Center of the European Commission called the Global Human Settlement Layer.
As in previous campaigns, we will ask you to shade the grid cells if they contain any built-up features.
We will aim to validate 50K points at least 5 times during the campaign, which will launch on 23rd September 2020. Put this date in your diary and join our campaign, with prizes and co-authorship to be won for participation.
Top 11 contributors will earn an Amazon voucher (valued from 175 to 500 Euros) AND co-authorship on a peer-reviewed scientific journal paper summarizing and making openly available the information collected.
Contributors ranking between 12 and 25 on the leaderboard will be offered a choice of an Amazon voucher of 100 to 150 Euros, OR, alternatively, co-authorship on a scientific paper.
Contributors ranking between 26 and 30 on the leaderboard will be offered an Amazon voucher ranging between 50 to 75 Euros.
