I want to make a dInSAR interferogram out of two sentinel SLC images each about 4 GB of size, but the problem is that my machine is a bit slow. 4 cores processor and 4 GB RAM and no special GPU. When I go to Radar>Coregistration >S1 TOPS Coregister and select the images and selecting my required subswath IW2 and first just three bursts. For VV polarization only.
At first it showed error that no orbit file is present so I manually downloaded the orbit files for each image for S1A and B total 4 orbit files.
When I run the process nothing starts and progress bar is at 0. Even the system is running fine as it should no professor cooling fan starts buzzing and it’s like I never even clicked on start.
Please tell any alternative way of selecting the IW2 for both images and later coregistering them. I even tried to seperate the subswath by selecting one image and going to S1TOPS in dropdown but when I open coregisteration wizard it says images must have subswaths type error.
