Where cropland is across Europe and Asia, 2015 (30 m)

Global Food Security-support Analysis Data (GFSAD) Cropland Extent 2015 Europe, Central Asia, Russia, Middle East product 30 m V001
land NASA LPCLOUD Level 3 GeoTIFF
In plain English

What it measures. A map showing where cropland exists across Europe, Central Asia, Russia, and the Middle East for the year 2015, marking each 30-meter pixel as cropland, non-cropland, or water.

How it's made. Created by feeding Landsat 7 and 8 imagery plus elevation data into a machine-learning classifier (a random forest) that learns to recognize cropland.

How & where you'd use it. Provides baseline data for agricultural studies, water sustainability, and food-security policymaking across a large stretch of the globe.

Official description

The NASA Making Earth System Data Records for Use in Research Environments ([MEaSUREs](https://earthdata.nasa.gov/about/competitive-programs/measures)) Global Food Security-support Analysis Data (GFSAD) data product provides cropland extent data over Europe, Central Asia, Russia and the Middle East for nominal year 2015 at 30 meter resolution (GFSAD30EUCEARUMECE). 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 GFSAD30EUCEARUMECE product uses a pixel-based supervised random forest machine learning algorithm to retrieve cropland extent from a combination of Landsat 7 Enhanced Thematic Mapper (ETM+), Landsat 8 Operational Land Imager (OLI) data, and elevation derived from the Shuttle Radar Topography Mission (SRTM) Version 3 data products. Each GFSAD30EUCEARUMECE GeoTIFF file contains a cropland extent layer that defines areas of cropland, non-cropland, and water bodies over a 10° by 10° area. Known Issues * Known issues, including constraints and limitations, are provided on page 20 of the ATBD.
