Optical Data Requirements

Approximate Start Date of Acquisition: April 1 (min) - September 1 previous year (preferred): Autumn images of the previous year are desirable to discriminate between winter and spring crops.
Approximate End Date of Acquisition: October 1 - Images acquired for specific days
Spatial Resolution: 30 m (min), 5-10 m (preferred): 30 m is required for crop area estimates, 5-10 meters is desirable for field-based biopar parameters retrieval (for intensive observation sub-site)
Temporal Frequency: 1-2 acquisitions per month: One cloud-free image composite per month is required for crop mapping. Two acquisitions per month is required for intensive observation sub-site
Latency of Data Delivery: weekly
Wavelengths Required: G,R,NIR
Across Swath: 210: To cover whole Kyiv region. 25 km is enough to cover intensive observation sub-region.
Along Track: 270: To cover whole Kyiv region. 15 km is enough to cover intensive observation sub-region.

SAR Data Requirements

Approximate Start Date of Acquisition: April 1 (min) - September 1 previous year (preferred): Autumn images of the previous year are desirable to discriminate between winter and spring crops.
Approximate End Date of Acquisition: October 1
Spatial Resolution: 30 m (min), 10 m (preferred): 30 m is required for crop area estimates, 10 meters is desirable due to SAR speckle
Temporal Frequency: 1-2 acquisitions per month: One image composite per month is required for crop mapping. Two acquisitions per month is desirable to test crop classification accuracy due to different incidence angles
Latency of Data Delivery: weekly
Wavelengths Required: X,C (min), X,C,L (preferred): Different wavelengths will help discriminate crop at different (low, medium, high) biomass level and should increase final crop classification accuracy
Polarization Quad polarization: Quad polarization is required to test crop classification accuracy using SAR and optical data. Also quad-pol data will be used to select best dual-polarization option.
Incidence Angle Restrictions: No restriction. Observations with different incidence angles will be used to select optimal range of incidence angles for crop classification
Across Track: 210: To cover whole Kyiv region.
Along Track: 270: To cover whole Kyiv region.
