I have the issue on some OLCI images.
I join some example below. In this example, I show the image in Radiance before applying the processing Radiance to Reflectance as well as a specific area in the output (Reflectance). Here, I showed only the 20th band, but this issue occur also in the orther bands (but not necessary with the same density or positions of black dots…)
Can you explain me marpet where I can find some invalid quality flags ?
In my output product (Reflectance), I can’t find any “quality flag” pannel…
One example (OLCI L1b) :
Name of the product used :
Radiance 20 : (before the processing “Radiance to Reflectance”)
Specific area of Reflectance 20 (caused by the Radiance to Reflectance processing)
I have exactly the same issue with other products.
I think that I have to select all the NaN with a band math operator in order to create a mask: how can I do that ??
I can’t find any operator isNaN in SNAP.
What is for you the issue with this processor if it’s not due to some atmospheric corrections (how is it possible to convert radiance to reflectance without these kind of corrections ???) ?
