I downloaded the scenes of Sentinel -1 for the entire 2017 year with the following characteristics:
Satellite platform: S1A and S1B
Product type: GRD
Sensor mode: IW
Order by: Descending
Relative orbit number: 153
I have 49 scenes with these characteristic. I need to do the preprocessing of these scenes and eliminate the speckle by averaging.
I created Graph with the next steps:
1.Apply-Orbit file(Add/Radar/Apply-Orbit file)
2.Thermal Noise Removal (Add/Radar/Radiometric/Thermal Noise Removal)
4.Terrain Correction (Add/Radar/Geometric/Terrain Correction/ Terran-Correction
5.LineartoFromDB (Add/Raster/Data Conversion/LineartoFromdB)
After Batch processing i did these steps:
Also, i used Slice Assembly and Subset before batch processing. I used Slice Assembly, because the area of interest was not always covered by one scene.
Is this all right? Do I need to take another step to get better results?
Can I use the same preprocessing for S1A and S1B?
Is there a presentation where preprocessing is explained.
