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:
Description:
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?
