Hello, everyone. l am new for proncessig sentinel 1. Now, i have a probelm.
Using gpt line, I want to convet SLC to GRD by myself.
Data: S1A_IW_SLC__1SDV_20161128T231449_20161128T231516_014149_016D93_256F

Is there any one could help solving this problem? I download the data from Xia, while, i got the same problem… i’ll keep my eyes on this page and waiting for a hero to come…
That’s strange. When I use your data, it doesn’t work. I’ve got the very well explicit error “-57”.
But when I test on one of my image (S1A_IW_SLC__1SSH_20171005T184524_20171005T184551_018681_01F83F_179F), it works well.
If your notice, you can see that the naming convention of Sentinel 1 products changed between our two acquisitions (yours begins with S1A_IW_SLC__1SDV and mines with S1A_IW_SLC__1SSH). Maybe that causes the problem. Maybe @lveci has any comment on the problem? Thanks in advance.
hello, I use other data is ok.
Maybe this data need some other parameter to process.
I understand that SH means single HH polarization and DV mean dual polarization VV and VH.
Some choices in the conversion SLC->GRD are debatable. I like keeping the very fine range spatial resolution. For feature tracking for example, it can be helpful to keep it with as much details as possible.
In my case, the multi-looked step is highly not suitable
