I want to shift from downloading Landsat8 imagery directly from USGS to the AWS service (https://pages.awscloud.com/public-data-sets-landsat.html).
I have some automated processes that are not accepting the TIF files from AWS. Upon closer inspection the file sizes differ substantially.
For example for scene LC80930842016347LGN00 if I download from EarthExplorer as LC80930842016347LGN00.tar.gz and extract all bands except B8 are 116,191KB.
When I download the bands individually from AWS (http://landsat-pds.s3.amazonaws.com/L8/093/084/LC80930842016347LGN00/index.html) all bands except B8 are around 60MB and the BQA band is only about 1MB.
Is there some compression going on in the AWS storage and if so, is there a process to transform these back to original so the Landsat_LDOPE tools will work?
