ERS-2 IMP data Preprocessing (Downloaded from Eolisa)

Microwave Toolbox
#1

Hi
I have an ERS-2 IMP dataset with .E2 Extension which was obtained from ESA Eolisa software.
I want to preprocess this dataset to fuse with ETM or ASTER datasets for geological purposes (Image fusion for geological mapping enhancement).
Please help me to correct and preprocess the ERS-2 dataset by listing all required steps, step by step.
thanks a lot.

  1. Radiometric calibration and conversion to db
  2. Speckle filtering (optional)
  3. Terrain Correction (use the same coordinate reference system as your ETM data)
  4. Create a stack of all products.
