Selection of Burst
Added by Kaarthikeyan R over 3 years ago
For the selection of the specific burst of Sentinel TOPS mode, I initially identified the respective burst associated with my AOI.
I tried using the command #SLC_copy_ScanSAR, with the details as mentioned in GAMMA documentation and also creating the tab files and folder as mentioned.
But still, it throws up an error I am unable to find my error.
Can you suggest a better way? (I have mentioned the attachment file)

Hello,
Your screen shot just shows that the file SLC_tab_20170107 is not present in the
current directory.
I suggest that you use script S1_import_SLC_from zipfiles first only for the
reference scene and enter - for the burst_number_table_ref.
In the imported SLC directory there will be a file that contains a listing of
the number of bursts in each swath iw1,iw2, and iw3.
The file is called temp.burst_number_table_ref. It will look something like this:
temporary reference burst number table that includes all bursts present
iw1_number_of_bursts: 26
iw1_first_burst: 251.110468
iw1_last_burst: 277.110467
iw2_number_of_bursts: 26
iw2_first_burst: 251.412179
iw2_last_burst: 277.412178
iw3_number_of_bursts: 26
iw3_first_burst: 250.803016
iw3_last_burst: 276.803015
copy and rename to something like ref.burst_number_table_ref
Edit this file to reflect the bursts you want. Then run the import script using
the updated burst_number_table_ref as an input argument 2.
reference burst number table that includes only the select bursts
iw1_number_of_bursts: 16
iw1_first_burst: 257.110468
iw1_last_burst: 274.110467
iw2_number_of_bursts: 15
iw2_first_burst: 257.412179
iw2_last_burst: 273.412178
The burst number of the first burst is 251.1110468, and successive bursts, add 1
to the burst number...
then edit the burst_table to reflect the desired swaths and bursts.
Run again for the reference scene, and make sure you get the correct area.
Then you can run this for your stack of SLCs....
Best regards,
Charles
