I was doing radiometric calibration of the sentinel 1 images . the following error appers every time i do radiometric calibration. would you please help me?
It can be something with RAM if image is too big based on Error: Cannot construct DataBuffer . You can find there what you could try to do in settings.
How much RAM does your computer have ? If you play around with the VM parameters listed in the post linked by @zubro, it would help you to know how much RAM you’re working with. And of course if you don’t need the full sentinel image, you could start by doing a subset.
