For Sentinel-1 images in and after mid-March 2018, is there any pre-processing step that we do not need to apply (comparing to images before that date)? If somebody has an info about the difference and the issues we should consider I appreciate his consideration and reply to this question.
Thanks. SO you mean for the data before March 13 I am good with the pre-processings that I have already done. Am I right? Or it is better to do all of them in the new updated SNAP?
If you have done pre-processing for the data acquired before the 13th of March with previous version of SNAP its fine. Important is to process all the new data with new version of SNAP
