[Sentinel-pds] Corrupted files

[Grega Milcinski]

Hi all,

Peter notified us about corrupted file on S3:
http://sentinel-s2-l1c.s3.amazonaws.com/tiles/39/L/XV/2015/11/25/0/B04.jp2

Based on this report we have done a thorough analysis of all jp2 files on S3 and identified 3 more tiles, where files were corrupted. We did not identify the cause for the problem. However, all of these files were from first batch (end of November) and corruption is probably related to:
-default java unzip, which we were using at the beginning or
-original source corruption (e.g. within sentinel hub zip files)

Since we did not identify any new problem in files from December on, we decided to leave this issue for now. We are analysing all new jp2 files so if the problem reappears, we should know.

In case you find some new problem, let us know.

Peter: thanks for heads up.

Regards
Grega
