Satellite:
Derived from a variety of crop masks generated from a variety of satellites (PROBA-V, Sentinel 1 and 2, Landsat)

Version:
ASAP crop mask (version 04) was updated on January 12, 2023.

Organization:
Food Security Unit of the Joint Research Centre-European Commission (JRC-EC).

Resource Abstract:
Global crop and rangeland masks at 0.004464285715 deg resolution (about 1/4 square kilometer). Each pixel represents the area fraction of the specific cover (i.e. percentage of the pixel with crops/rangeland). Data ranges between 1 and 100 showing the % value. These layers were generated for ASAP, combining existing data sets (Fritz, S., Lesiv, M., Perez Guzman, K., See, L., Meroni, M., Collivignarelli, F. and Rembold, F., Development of a new cropland and rangeland Area Fraction Image at 500 m for the ASAP system, Publications Office of the European Union, Luxembourg, 2024, doi:10.2760/32935, JRC137153. doi:10.2760/32935). The data sets were last updated on 01-12-2023 (version 04).

Reprocessing for GIMMS/GLAM applications:

Pixels with crop area fraction ranging from 1-100 percent were assigned a binary value of 1.
The resulting 500-m binary dataset was mapped to the 500-m VIIRS grid and subsequently resampled to a 300-m spatial resolution to match the OLCI grid.
