Biomass Sentinel-2

[AMuraro]

Hello

I would like to calculate the correlation of the spectral indices applied to the Sentinel-2 image with data from reference (chlorophyll, for example). Is it possible to extract this information (r²) with snap? If yea, what is the tool and how it’s work?

Also would anyone know how I can create a biomass model from a multispectral image?
Thank you!

you can use the correlative plot view to link numerical point information to the raster values underneath

Correlation between two rasters?

Just a short addition to johngan’s very good answer: Instead of extracting single values, you can also directly use the scatter plot tool [grafik] to relate two rasters (given that they are within one product) If you have point data with numerical values, you can even the correlative plot view: [grafik]

but do the points need to be a vector with attributes or can it be a csv without latitude / longitude?

Thank you

if you want to correlate the remote sensing imagery to any co-variable you need at least one numerical attribute.

But you can import this as Shapefile, CSV, ect…
