Hello every body and hope you are doing great, i want to ask for help please, i am using SNAP to process my Sentinel 1A data but i am having some challenges of java.io.IOException: DimapProductReader: Unable to read file as attached.
I will be greatful if my problem will get solution from you.
Hello,
Have you copied the *.dim file to another location?
The DIMAP format consists of two components. The *.dim file and the *.data directory. You need to move both.
In addition, it would be helpful if you provide the text of the error. You could have copy & pasted the text from the second screen.
Also, the log file is always useful. SNAP FAQs - How to find the log files?

You haven’t answered if you have moved the file.
Have you checked the content of the directory:
D:\RASHEED\SENTINEL-1A_KB2\SNAP-StaMPS_1\PS_Work_1\1_TopSAR-Split_Orbit\S1A_IW_SLC__1SDV_20201021T112644_20201021T112711_034894_041182_740D_Orb.data? Does it contain the i_IW2_VV.img file?
I haven’t moved the file, but now i checked
D:\RASHEED\SENTINEL-1A_KB2\SNAP-StaMPS_1\PS_Work_1\1_TopSAR-Split_Orbit\S1A_IW_SLC__1SDV_20201021T112644_20201021T112711_034894_041182_740D_Orb.data the i_IW2_VV.img file is not available
So, something went wrong with previous processing. Actually, an error or at least a warning should have been displayed. Maybe you can still find out what happened. Or retry the processing.
