Re: Why there are many NaN in processing sentinel-2 ?

Dear fsteinmetz, Thank you for your patience and help. How to specify the downloaded global-surface-water parameters for run_atm_corr.Because I found that it may be because the global-surface-water data to be downloaded is large, I want to download it and then crop a piece as an input parameter.

Re: Why there are many NaN in processing sentinel-2 ?

Dear fsteinmetz,

When processing sentinel2, I only get the reflectance of the water body after atmospheric correction. The land is all NaN. How do I get the reflectance of the land?

Thank you very much!

Best,

Why there are many NaN in processing sentinel-2 ?

Dear

Hello, I am using polymer-v4.13 to process sentinel-2 data (cloudiness is less than 10%), and the result is that most of the pixels in non-water bodies have NaN values. What is the reason?

Thinks.
