Tillage change detection

  • A two scale thresholding algorithm classifying temporal changes of S1 IW VH due to tillage practices only.
  • The algorithm is applied over bare or scarcely vegetated agricultural fields identified either from S2 NDVI or, in case of cloud cover, S1 VH/VV ratio.
  • The output is a binary mask at ~ 0.1 km spatial resolution (~ 0.04 km pixel size).
  • The validation has been carried out in “Validation of Tilled Change Maps” (D7.13).
