I am working with a Sentinel 1 SLC IW image (VV+VH) and trying to calibrate the data in the SNAP toolbox. However, it keeps returning the error "cannot construct data buffer"
Does anyone have any idea why this might be happening?
As mentioned the error is due to RAM but not the system RAM, the available RAM for SNAP. you can change the configuration in the snappy.ini file located in the snappy folder. and increase available RAM Change the line
to e.g. java_max_mem: 6G A recommended value is 70%-80% of the available RAM in your system.
