EO Data Processing Levels

Описание: Are you aware of the different processing levels of EO Data and if so, are you aware how they are defined?
Without details the levels can be summarised as:
L0 - Unprocessed raw instrument data
L1 - Georeferenced data in sensor units
L2- Derived geophysical variables projected to coordinate reference systems.
L3 - Combined Georeferenced data
L4 - Processed to greatest amount, possibly including modelled or interpolated data and data from different sensors.
