sen2cor ndvi

Optical Toolbox sen2cor

Hello guys,

This looks like a great community and I am sure it can help me improve! I started this wonderful sentinel journey very recently so pls forgive my newbieness while i join the dots. I am doing an assignment and would like to find a pythonic way to calculate ndvi from an l2a product generated by sen2cor.

but before… some context - I calculated ndvi on a L1C product and I assume that it can be improved by looking at the boa reflectances although it can give a pretty good idea. Is this correct?

Can you point me to a Python script that can help me generate ndvi (ideally with color map) from sen2cor l2a output?

This exercise will definitely not be easy for a newbie lke me, but will help me understand more!

Is your question solved by now? :wink:

I have a doubt in this regarding…
To compute NDVI should we carry out sen2cor and then compute NDVI or can we directly compute NDVI from the L1C product?

This issue is well explained in the following posts, please have a look,

TOA and BOA

sen2cor converts L1C products into L2A

I went through the threads @falahfakhri… So u suggest carrying out sen2cor and covert into a L2A product and then compute NDVI?

Yes, exactly, especially when you have a comparison of multi-date,

I installed the standalone sen2cor processor in my windows OS. Have installed the plugins in SNAP too. But, I couldnt run the process. Could you help me with this if you have carried out sen2cor earlier in windows environment?

I explained it in the following post, pleas take a look at the part of the installation and implementation of sen2cor
