Hi all, I am new here (FORUM) and new at Radar!!
I want to do Change Vector Analysis using Sentinel 1 and Sentinel 2 data. I use Sentinel 1 SLC, IW, with double polarization (VV-VH) and Sentinel 2 LVL 2 products.
From S-1 i want to extract amplitude images (VV-VH), variance texture images (VV-VH), contrast texture images (VV-VH).
What I have done so far is shown below:
1)Calibration (Complex Output, with sigma0)
2)Thermal Noise Removal (Remove Thermal Noise)
4)Speckle Filtering (Refined Lee)
6)Grey Level Co-Occurence Matrix
8)SLC to GRD
Is this flowchart correct? The methodology was taken from this paper “Fusion of Sentinel-1A and Sentinel-2A data for land cover mapping: a case study in the lower Magdalena region, Colombia”.
Also, for step 5, I have choose GR square pixel, No of Range looks=4, no of azimuth=1 and Mean square GR pixel size=14.3. My question is, after choosing those parameters will I be able to make Resampling with pixel size 10*10 (step 7 of the above methodology)?
