I’m new to snap and trying to automate some data conversions with gpt. I’ve tried to understand the tutorial and the most helpful thread I’ve found on this topic so far ([here] (Best practice to convert and reproject Sentinel-3 radiances to reflectance)), along with gpt -h and gpt Reproject -h.
I can successfully extract a band (using BandExtract) and reproject the data using the Reproject example from the two links above. However, I cannot figure out the correct XML to reproject using collateWith and an existing HDF5 file I have.
In the GUI GraphBuilder and Reproject, I can’t find a way to set a collocateWith option. Am I missing something there? I only see “Custom” and “Predefined” CRS options.
In the GUI GraphBuilder and Collocate (is this even what I should be using?), I see an error (red text) that states, "Error: [NodeID Collocate] Operate ‘CollocateOp’: Mandatory source product (field ‘masterProduct’) not set.
Can someone provide a working example for this?
