Topic: dune displacement with landsat 8, panchromatic band
i am trying to quantify dune motion in the gobi desert using two overlapping landsat 8 images (pachromatic band).
i masked the interested area to be sure, to quantify sand motion only in the investigated area.
when i correlate the two images, i use a window size x32 and y32, step 16 and search range 10.
with these parameters i quantify a dune motion of 8 meters in 3years.
anyone can suggest if the used parameters are correct because i have a little doubt on my results.
