[dataset] Global Synergy Cropland Map v3.0

Information on global cropland distribution and agricultural production is critical for the world's agricultural monitoring and food security. Here, datasets of cropland extent and agricultural production are presented. A new Self-adapting Statistics Allocation Model (SASAM) to develop the global map of cropland distribution was proposed. Cropland area statistics are used to rank the input cropland maps, and then a scoring table is built to indicate the agreement among the input datasets.
