[quote=“shahbazbaig, post:57, topic:2222”]I tried TOPSAR-Split using SNAP instead of Python, but its also creating very big file as output.

have you reduced the number of bursts as in the screenshot here? Apply orbit file error in S1-TOPS Coregistration
Some remarks on the steps:
- Border Noise removal is not required for SLC products
- I would apply a speckle filter earlier (before the conversion to db and multi-looking)
- Multi-looking is not mandatory. After range doppler terrain correction your pixels are converted to squares anyhow.
- The conversion to dB only makes sense if you search for changes in the low backscatter areas. The information is kind of the same but low values get streched while high values are shifted towards the mean. Your histogram then shows a more normal distribution.
