Leaf area index Sentinel2 L1C

Optical Toolbox
#1

Hi to everyone,
i wanted ask you if you know how to get LAI( leaf area index) in SNAP. Furthermore do you know how to cut an image with SNAP ? My aim is to exstract coastal line 5 km from sea and 5 km from land. Hope you can give me a solution. Thanks in advance.

Hi gaetano,

to your first question about ‘LAI’: I never did it, but how about calculating an NDVI with a threshold value and divide it by the total area?

to your second question about ‘cut an image’: You can make a subset. You can see a detailed description here:

Cheers,

Hello Gaetano,

I would assume that you can use NDVI (Normalize Difference Vegetation Index) for your purpose. Or what exactly do you need?

Cheers,
