It is great that the BEAM capabilities where transferred to SNAP.
I have been exploring options to create RGBs from S-3 OLCI using the command line and pconvert. As you know the 21 radiances from OLCI are in individual ncdfs. As pconvert only accepts 1 file as input, this file needs to contain at least 3 bands for the RGB.
So far, I got a work-around where as a first step, I create a temporary ncdf file that contains my 3 bands of interest (e…g, using IDL or shell script) from a specific OLCI file and I then feed that new, 3-layer ncdf filepath to pconvert to create the rgb in whichever format I want. It works, but it’s a 2 step process.
Is there a simpler way to do all that in one go by
a) either using an XML file that lists the filepaths of the 3 individual OLCI bands as input into pconvert? (If so could you please share an XML template).
b) or is there a way to create this 3-layer ncdf with gpt ? (I don’t think so but I am inquiring in case it’s possible)
