Hi All,
I have answered my own post by digging into the script shared in this previous post:
, but it’s not very obvious so I’ll spell it out here for future users:.
For those wanting to use GPT tools / operators in snappy this is the general procedure, in python:
import snappy
snappy.GPF.getDefaultInstance().getOperatorSpiRegistry().loadOperatorSpis() # Load all available operators
HashMap = snappy.jpy.get_type(‘java.util.HashMap’)
parameters = HashMap() #Specify the parameters, these can be seen from the command line using gpt -h operator
parameters.put(‘sensor’,‘OLCI’)
parameters.put(‘copyNonSpectralBands’,‘False’) # I had to use this option due to an error
refl_product = GPF.createProduct(‘Rad2Refl’, parameters, sub_product) # compute the product from input called sub_product
Hope that helps!
This can also be seen in the snappy_bandmaths.py example and here: [quote=“marpet, post:2, topic:2636”]
