I am trying to create a DEM with using 2 Sentinel-1 images. After creating interferogram, I tried to unwrap it using Snaphu. In the beginning of the process, it ended up with an error like this:
snaphu v1.4.2
27 parameters input from file snaphu.conf (84 lines total)
Logging run-time parameters to file snaphu.log
one or more interferogram dimensions too large
The data I am using is the data I obtained from Sentinel interferometry tutorial. But somehow it didn’t work for me. Does this mean I should subset and make the interferogram smaller? Is it possible? If it is, how is it supposed to be done?
It started to proceed properly, thank you for the help. But it got cut off in between due to the error “out of memory”.
The virtual memory tool I am using is Cygwin. I am supposed to increase the memory for Cygwin I guess. Did a search for it but couldn’t find something helpful. Do you know how it can be done?
