Hello Peter, Thanks for using the tool! Yes, sadly the docmentation is a bit lacking and I'll work on improving that. With regards to that specific bit of code, it uses the I hope this helps. Best regards, Arin |
Thank you Arin, Why it should be manually specified?I think it will be nice to create the common area automatically. |
Hello, Sorry for the delay in replying! They were just manually specified for that specific example but there could be a function to automatically crop the candidate and reference imagery so that they align with each other (e.g. using gdal or something). At the moment, this kind of feature isn't on the table but if I get time I can try to scope something out. I can definitely see how that kind of function could be helpful. Thanks, Arin |
Hello @arincos, |
I found this tool very impressive and tried to use it. However, I couldn't quite understand it very much. Is there a detail document for it?
e.g.
When I looked into generating the pseudo invariant feature pixels (pif.py), I don't quite understand the lines:
for full_filename, cropped_filename in zip(full_candidate_filenames, candidate_filenames):
subprocess.check_call(['gdal_translate', '-projwin', '545000', '4136000', '601000', '4084000', full_filename, cropped_filename])
for full_filename, cropped_filename in zip(full_reference_filenames, reference_filenames):
subprocess.check_call(['gdal_translate', '-projwin', '545000', '4136000', '601000', '4084000', full_filename, cropped_filename])
What does it exactly mean?
Appreciate your help.
Peter
