Topic: dune displacement map using sentinel 2 data
i would like to quantify sand motion in a sand channel in the gobi desert on the earth using two sentinel 2 dataset.
these data are multibands and i used the infrared 10m/pixel resolution for every image.
these images are just ortorectified and i think i could quantify the displacement map.
for the frequency correlator parameters i used the frequency correlator and i used the based parameters : windows size x initial 128 final 32
windows size y initial 128 final 32
step x 16 step y 16
my question is this: these parameters are correct??????????
the displacement map is little strange but the vector field is in agreement with the slip faces of the dunes.
thanks for your help
