ESA WorldCereal 10 m 2021 v100

ESA WorldCereal 2021 products v100

The European Space Agency (ESA) WorldCereal 10m 2021 product suite consist of global-scale annual and seasonal crop maps and (where applicable) their related confidence. Every file in this repository contains up to 106 agro-ecological zone (AEZ) products which were all processed with respect to their own regional seasonality and should be considered as independent products.

Naming convention of the ZIP files is as follows:

WorldCereal_{year}_{season}_{product}_{classification|confidence}.zip

The actual AEZ-based GeoTIFF files inside each ZIP are named according to following convention:

{AEZ_id}_{season}_{product}_{startdate}_{enddate}_{classification|confidence}.tif

The seasons are defined in Table 1. Note that cereals as described by WorldCereal include wheat, barley and rye, which belong to the Triticeae tribe. Next to the actual WorldCereal products, this repository contains the files "WorldCereal_AEZ.geojson" that contains the AEZ description and outline, as well as "QGIS_stylefiles.zip" which contains QGIS style files (.qml) for product visualization purposes.

Season
Description

tc-annual
A one-year cycle being defined in a region by the end of the last considered growing season

tc-wintercereals
The main cereals season defined in a region

tc-springcereals
Optional springcereals season, only defined in certain AEZ

tc-maize-main
The main maize season defined in a region

tc-maize-second
Optional second maize season, only defined in certain AEZ.

Note: AEZs for which no irrigation product is available were not processed because of the unavailability of thermal Landsat data.
