Minimize Spatial Resolution

Full Resolution (FR)

To simplify OLCI operations, maximise instrument autonomy and offer maximum flexibility for data processing and re-analysis, OLCI always operates (both land and ocean) in full resolution mode.

For the nominal orbit, at sub-satellite point, full spatial resolution of the OLCI instrument is approximately 300 m.

 

Reduced Resolution (RR)

From Level-1B, OLCI products are provided in a sub-sampled version, at a resolution four times coarser and referred to as RR.

RR is obtained by averaging the signal of 16 full spatial resolution pixels. More precisely, four adjacent pixels across track for four successive pixel lines along track are used.

For the nominal orbit, at sub-satellite point, reduced spatial resolution of the OLCI instrument is approximately 1.2 km.
