General Steps for Sentinel-1 Data Preprocessing

@JunqianW, May I know the reason why do you apply the image subset at the last stage instead of the beginning to reduce the file size and computing resource?

#22

yes, most speckle filters are designed for the power-scaled data

@ABraun, so the procedure for Sentinel-1 pre-processing should be operated as follow sequence!?:

  1. Apply orbit file

  2. GRD border noise removal (optional)

  3. Thermal noise removal

  4. Speckle filtering

  5. Radiometric calibration

  6. Terrain correction

  7. Subset

#24

You can perform the subset earlier, but yes.
