Hi Sen4CAP team,

From the “Sen4CAP_DDF_v1.2_CropType.pdf”, it says

And from “Data_calibration_final_after_smote_xxxx_xxxx.csv”, I see this

Are values in column I Ratio VV/VH?
If so, how to calculate it?

Regards,
Ant

Hello Ant,

Yes
The calculation of the ratio is done at the pixel-level (back VV / back VH), then the mean value of this ratio is calculated by parcel.

Best regards,

Philippe

@Philippe_Malcorps

Thank you so much for the explanation. I see.

I guess the values in column E and G are the mean values of backscattering of VV and VH at parcel level, right?
