Cannot construct databuffer can mean that you do not have enough disk space for the operation.

#3

Sorry to correct you Marcus, but it is not the disk space but the memory.

#4

Right, thanks marpet!

#5

Thanks marpet and mengdahl ya I have 20 Gb free in C drive and also i save the sen2cor output in F drive which have 200 gb free. Today i agained tried and i got this error message

The 1st problem : you didnt import the whole scene in native resolution.
The 2nd problem : It’s not a real problem, just a wrong string/print, your images must be corrected.

Anyone knows how to get TOA_Reflectance from Digital Number (Digital Counts)? Is it for real DN/10000??

#7

According to the Sentinel-2 Products Specification Document (PSD) on page 420 this is correct. The QUANTIFICATION_VALUE is 10000
