Sentinel 2 data from Amazon AWS!

Hello,

I am wondering about the publicly available Sentinel 2 data in AWS. Since the data structure is different from ESA SAFE data format, my question is how I can preprocess (conversion and radiometric correction) the imageries in absence of the ‘MTD_MSIL1C’ file?

Hello Adballa,

For the reason you pointed out, plus a different folder structure, one cannot run Sen2Cor on S2 data from AWS.
I it is possible to process these data applying solutions implemented in sen2Cor using in-house developed scripts and downloading missing metadata… but to be honest I do not see a reason in doing so, when there is a well defined and user friendly processing environment.
I know that some people sometimes still use remote sensing data without any preprocessing (atmospheric and topographic corrections), but imho quality of such analyses could/should be put in question.

Hello.

Actually Sen2Cor can be run on the AWS S2 data.
Please take a look at this tools which has been developed for serving this purpose.
I have been using it many times (including with Sen2Cor) and it is ok.
Have you any questions, please send me an email.

Cheers,
Cosmin.
