Global Crop Mapping at Field Scale

demonstrate the feasibility of global crop mapping at field scale based on open high resolution EO data (S1, S2, L8);

mapping at 10 m the global extent of annual cropland and two of the major

staple crops wheat and maize on a seasonal basis;

build a collaborative approach to exchange with the agricultural community relevant in-situ data sets and disseminate the global crop mapping results

showcase the utility of the WorldCereal products by conducting use case studies related to the GEOGLAM initiative and SDG reporting;

LSTM – Managing Water for Agriculture

• Provides Thermal Infra-Red observations in high spatial resolution and temporal frequency in support of agriculture

management services What

Why

Improves sustainable water productivity at field scale

Addresses increasing Water and Food Security issues in a world of increasing water scarcity and variability

Responds to major agricultural & environmental policies

How

Unprecedented 30-50 meter observations in 3-5 thermal bands

Frequent Land Surface Temperature (LST) at daily to 3 days revisit World-class instrument providing 1-1.5K LST radiometric accuracy

Monitoring of water productivity

biomass production per hectare per cubic meter of water consumed with distinction is made between rain-fed and water-fed agriculture as well as

evapotranspiration originating from precipitation (‘green’ water) and incremental evaporation originating from irrigation (‘blue’ water)
