I am having some problems with the last steps of the tutorial about Satellite Derivated Bathymetry for SNAP (https://rus-copernicus.eu/portal/wp-content/uploads/library/education/training/COAS01_BathymetryDerivation_Greece.pdf).
I have followed all the steps, very rigorously, working on my own ROI (data products: S2B_MSIL2A_20220416T101559_N0400_R065_T32TMK_20220416T175100)
here we are, I am looking for hours on the internet to find a solution but nothing.
Now i cannot go ahead anymore. i don’t understand what am supposed to do after the creation of the new band B3B2 (page n. 24 in the document).
I go to ‘Raster> Export > Extract pixel values’, then i select the first parameter, then switch to parameters tab:
My question is: what is the meaning of add this file during this step? And which is the file format/kind that i have to select and import in the ‘Coordinates’ panel’?
I was trying to import a product from GEBCO of my ROI seabed bathymetry, but it doesn’t work… I thought that during this step the csv file required was the one containing the grid data needed for the comparison of the computed bathymetry.
These are the bathymetric data i want to insert in my work.
