Reprojection s3 slstr issue

[marpet]

Hi,

simple things first. You can simplify the reading of the product.

reader500 =  snappy.ProductIO.readProduct(in_file, 'Sen3_SLSTRL1B_500m')

I think this will work.
Regarding the memory issue. You can configure how much memory can be used. Please see this post:

Snappy error - ProductIO.writeProduct

I’m not sure, I’m not very familiar with snappy, but I think you have to set a value in the jpyconfig.py script in the snappy folder. Try setting jvm_maxmem = None to jvm_maxmem = '6G' Another place to change the memory usage might be in snappy.ini in the snappy folder. Change the line # java_max_mem: 4G to e.g. java_max_mem: 6G
