  • The SYN L2 VGT-like processing includes similar algorithms than PROBA-V concerning projection on 1 km grid and composite methods. As a result of this improvement, more geographical details are available on VGT-like product, providing a dataset more consistent with the actual geographical area.
  • Concerning VGT composite methods, several selection rules have been added in addition to the "maximum NDVI" one. These rules are the same than the one applied on PROBA-V datasets and are driven by configuration parameters.
  • The cloud and snow/ice flags defined at SYNERGY L2 processing are now duplicated in VGT flags for consistency reason. In addition, several issues detected related to the cloud flag, such as blockiness detected at the edge of the cloud mask have been corrected.

  • Correction of NDVI set to 0 instead of _FillValue over ocean in VG products
  • Improving VGS composite method
