Reconstructed, unprocessed, full resolution instrument data; artifacts and duplicates removed.
Level 0 plus time-referenced and annotated with calibration coefficients and georeferencing parameters (level 0 is fully recoverable from level 1a data).
Level 1a processed to sensor units (level 0 not recoverable)
Derived variables (e. g., NDVI, height, fluorescence) at the level 1 resolution.
Level 2 mapped to uniform grid, missing points gap filled; overlapping images combined
'phenotypes' derived variables associated with a particular plant or genotype rather than a spatial location
