Hello,

Polymer has indeed been applied to GOCI data in the past, as mentioned on the homepage, but the algorithm has been entirely rewritten and currently, GOCI data are not supported. The GOCI reader would have to be rewritten as well.

Kind regards,
François

Hi Zheegang, I understand that you would like to get the water reflectance at MODIS bands that don't saturate. However I don't think you will be able to do it properly. Let me explain. It is indeed possible to adjust the bands provided by Polymer. This is done via the argument bands_rw to the functi...

Indeed, the issue is not fully solved yet unfortunately.
I have just uploaded the required files to the forum, so that you can download them until the issue is fully solved: see topic viewtopic.php?f=5&t=93
Cheers,

Polymer's auxiliary data should usually be available with the command "make auxdata_all", but in case it does not work, the auxiliary data can be downloaded here and uncompressed in Polymer's folder.

For your information, the files are now available again.

François

Dear zhangYingyin,
Apologies, we are having a hardware issue again, and we are trying to restore it as soon as possible. When it is done, the files will be available again for download.
Kind regards,
François

Dear Ding,

You can use the script tools/make_L1C.py to generate L1C files from L1A. This script uses l2gen. See also section 2.4 of the readme file.

Yes indeed, the SVC update follows an update of the algorithm.

Hello, There are many parameters that can be tuned, but most likely none that would improve your results easily. Unfortunately Polymer is known to retrieve underestimated values of water reflectance in moderately to highly turbid waters. We are doing research on this topic and hopefully this will im...

Can you check that luts.py has not been modified ? The line 999 of this file is part of a multi-line statement, and I don't see why there would be an invalid syntax here. Or double-check that you are not using python2 by accident, I think this might be the most likely issue. Just type $ python --ver...
