Layerstack sentinel-1 and coherence and GLCM

now I understand, this was not fully clear to me. Some questions to narrow it down:

  • Are all inputs of the layer stack terrain corrected and projected into the same coordinate reference system?
  • If all are terrain corrected you can try Radar > Coregistration > Stack Tools > Create Stack (select Product Geolocation as Initial Offset Method)
  • Have you visually checked all bands after stacking?
