Checklist for data submission

1. The cropland extent of the test regions at 10m spatial resolution in the three test regions, with following further specifications:

a) For Afghanistan (Nangarhar province): temporal cropland extent distribution of April 2022.

Data Description:

2. Training samples: We will provide a limited number of training samples for cropland mapping, participants can also collect some training samples by themselves as cropland extent can be visually interpreted from Google Earth and Satellite images. Particularly, for the cropland mapping in Afghanistan, training samples were collected in April 2022, and the model is used to identify cropland extent in the same period.

May the best model win!
