Minimize Spatial Resolution

The SYN Level-1 radiometric measurements are derived from full resolution OLCI Level-1B (~300 m) and SLSTR Level-1B products (500 m for S1-S6 and 1000 m for S7-S8 and F1-F2). The misregistrations or correspondence grids are provided on the SYN reference grid, i.e. the OLCI acquisition geometry:

  • OLCI pixel resolution (FR ~300m) grid for each camera image, corresponding to each OLCI camera image m = 1 to 5 in its acquisition geometry

At Level-2, a resampling to the OLCI L1b image grid is performed, taking into account the mis-registration and DEM-corrected geolocation information included in the SYN Level-1 product. All datasets are then provided in full resolution (~300 m) on the ortho-geolocated OLCI L1B image grid.

VGK, VGT-P and VGT-S products are provided on a regular latitude-longitude grid, with an equatorial sampling distance of 1 km (i.e. the 1km Plate Carrée grid).

The SYN AOD products are provided on a wider resolution, created from OLCI image grid. Each super pixel is representing 15 by 15 300m OLCI pixels. Resolution is then 4.5 km.
