Training of CropLand Mask

Hello, can anyone tell me that whether Cropland Mask is already trained or is has to be trained?

hello @idreegis,

Cropland mask is a product of Sen2-Agri also known as L4A. You need to have a training data or vector polygons in order to produce that product. Please see the Software User Manual.

You can also check my previous posts/questions on creating the training data or training polygons.
