I have downloaded the scene: S1A - SLC with both polarisations (VV and VH).
I am however, believing there is issue with the processed outputs. I applied:
- Orbit file
- Calibration
- TOPS Deburst
- Terrain Flattening*
The issue is that in the viewer the image appears ‘smaller’ after each step. In that, after Step 1. the viewer shows, I estimate about a a third of the original image. After Step 3. it appears only as a single strip (previously between bursts). And after Step 4. the output shows no values. That is to say, 0 for intensity values when viewing the greyscale histogram.
Believing there is something I am not doing right. Should there be a particular reason why outputs are seemingly being reduced?
