Error when processing Sentinel-1


#1

Dear SNAP developers and users,
I am a new user of SNAP, I tried to process Sentinel-1 data, the first step is radiometric-calibration, after this I wanted to do geometric correction, I used Geometric-ellipsoid correction-average height range-doppler, but error occurred, the error message is
Is there anyone know what’s the problem? It would be appreciated if someone could help me out on this.
Many thanks,
Liyun

Hi @dlydai,
first of all, let me welcome you as a new SNAP user.

If you have a question, it’s good when you open a dedicated thread for it. I did this for you.

The error message is hardly readable in the image. Can you attach it in a higher resolution?
I see it says that the product can’t be written. can you check the path and if you have write permission?

Hi marpet,
Thanks for your reply. The error message is :
A problem occurred during processing the target product processing.
Type: operatorException
Message: Not able to write product file “C:\Users\mfh278\Downloads\calibration data\S1B_EW_GRDM_1SSH_20170516T110027_20170516T110132_005622_009D90_52A4_Cal_EC”

even if I changed the path, the same error happened.

What output format did you select?


#5

I chose BEAM-DIMAP.
I can do other correction, such as stereographic_south_pole, WGS84. but I can not do polar stereographic.


#6

I’m not sure but maybe the EW mode is not compatible with polar stereographic projections. Where is your data located?


#7

my data is located in the antarctic. Somebody hasd used sarscape to get it .


#8

what happens when you use WGS84 as an output? Maybe you can re-project afterwards.
