Pre-processing SLC data in SNAP


I am unable to preprocess SLC dataset in SNAP as i get the following error “Cannot construct data buffer”.
I learnt that it is due to insufficient memory available for SNAP. I have a total of 16 GB of RAM in the system.
I tried to locate SNAPPY folder in my system to allocate more memory to Snappy however, i am unable to locate the same.
I searched in the python lib and .snap folder but in vain.
Kindly please suggest any other alternative.

You need to tweak the Java Virtual Machine (JVM) settings and tile-cache in the options. Please search the forum for more information.

ps. I would recommend that you do your pre-processing via graphs run via the gpt or the GUI. Using snappy will cause a degradation in performance.
