Thank you Marco,
yes, when I say “the first input images” , it means the first image in the input image sequence, or Image1.jp2 in my example.
I have tested the gpt mosaic with or without -SsourceProducts= keyword as you suggested. I notice without the SsourceProducts keyword gives me correct mosaicking result. Any clue why?
Another issue is , as discussed in a previous post, the metadata information is lost when mosaicking tiles; then how can I update the metadata (esp. band wavelength) of the mosaicked image using gpt for further spectral processing? (an manual approach mentioned in this post, but I would like to let the workflow run in gpt)
Thank you,
Chui,
