I am processing an image from Sentinel 1_IW_SLC, and when I want to do the Calibration (after having applied the Orbit File and the TOPS Split operator without problems) I get this error message:
“cannot construct data buffer” often means the software requires more RAM than is available. Use Windows Task Manager to see how much RAM is available and what is using it. Web browsers have become memory hogs, so it is not unusual to find that you have to closse the web browser while processing data.
