I’m trying to do a land cover classification of SLC Sentinel-1 dual-pol data. I processed the product with the following steps:
- apply orbit file
Then I produced GLCM and I applied a speckle filter to the Terrain-Corrected product, in order to make an H-alpha decomposition.
After that i tried to include the three products (GLCM, H-alpha, speckled data) into classification data but, both with KNN and RF algorithm the image I obtain isn’t all classified, as in the screenshot which is following:
As you can see water surface is not at all classified, most of the pixel are set as “NaN”
Anyone knows what I’m doing wrong?
