Which Terrain-correction is being in python applied?

Dear all,

i am kind of confused here. I am working with S1 GRD images and I perform a terrain correction using python and the following line of code:

GPF.createProduct('Terrain-Correction', parameters, image)

It is not clear to me what kind of correction is performed here though; is it a range-doppler, sar simulation or something else?

looking with the command line
gpt Terrain-Correction -h confuses me a bit more since it states:

  RD method for orthorectification

Which one should I look in the snap help wizzard to get more infos how the terrain-correction is it done?


it is the Range Doppler (RD) Terrain Correction operator.

Many thanks for clearing this up obarrilero!
