Reference data inventory for WorldCereal
Thanks for supporting the WorldCereal project. WorldCereal has the ambition to consolidate, build upon, improve and extend existing crop mapping technologies in an overarching system that is designed to work from a local to global scale and that can be operated by a wide variety of users from different communities. In order to generate accurate maps of cropland and crop type it is indispensable to have at our disposal good reference data which can be used for the training of classification algorithms and for validating of land cover and crop type maps.

Aim of this questionnaire is to conduct a data inventory for the WorldCereal project. We would like to get a general overview of the datasets within your organization that can be opened and shared with the WorldCereal project. The minimum datasets for training and validation would be observations of land cover and/or crop type at a certain location and time. Of course we are also interested in other supporting data like crop calendars, prevailing water management etc. We respect your trust and protect your privacy under the European Union General Data Protection Regulation (GDPR).

By filling in this questionnaire you can help us to gain insight about reference data for the WorldCereal system. It should take less than 10 minutes of your time to complete. Thank you for your help.  If you have any questions, please contact Arun Pratihast ( or Hendrik Boogaard (
