The Land Processes Distributed Active Archive Center (LP DAAC) is pleased to announce the availability of the The NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Global Food Security-support Analysis Data 30 meter (GFSAD30) Cropland Extent data product.The monitoring of global cropland extent is critical for policymaking and provides important baseline data that are used in many agricultural cropland studies pertaining to water sustainability and food security. The GFSAD30 collection provides cropland extent data across the globe, divided and distributed into 7 separate regional datasets, for nominal year 2015 (2010 for North America) at 30 meter resolution. Additionally, the validation dataset used to conduct an independent accuracy assessment of global cropland extent is available.
The Digital Object Identifier (DOI) for each dataset is given below to provide users with a persistent link to the product information.
