Hi Sean,
Thanks for your solutions, it is what I want to do. Because I need to generate many products from one whole granule imagery to further process using my programs so that I must consider the disk space in a big ROI.
This XML file works perfectly!:grin:
Thank you again!
Regards,
Zhigang

how to reduce the size of files generated by l2gen
Thanks, George. I did use the HDF5 and the file includes the Rrs, rhos, and view geometries. I will try to use NetCDF.
Thank you, again!

how to reduce the size of files generated by l2gen
Hi all,I am looking for a solution to reduce the file size when I process the MODIS data using l2gen. As you know, one whole granule of MODIS L2 data including the Rrs at all wavelengths is about 500M or even more, so that a long-time series requires a big space to store them. I am wondering whether...

gpt.sh reprojection issue
Hi Jun,
You may try to use the Mosaic tool via gpt.sh, it is able to generate images with the same sizes. A GPT Cookbook including Mosaic can be found in SeaDAS help document.

issue: chl_hu: incompatible sensor wavelengths for this algorithm for l7etm
Thanks, Rakesh. I will try it, and I do believe that it can avoid the Chl_hu problem.
But, there are also some problems for Rayleigh-Luts of L7ETM, which results in uncorrect Lr (for example, Lr>Lt).
Maybe, for this problem, we should expect the next release of SeaDAS.:grin:

Hi Don,Exactly. after all, the landsat 5 and landsat 7 is not very suitable for the ocean color, and I just wanna test these two bundles.:grin:Also, the values of rhos_478 and rhos_560 derived the landsat 7 were negative for my tested images (LE07_L1TP_119038_20181216_20190111_01_T1 and LE07_L1TP_11...

python calls shell to l2gen error: l2gen not found. How to set env in python script?
Try to use
source ~/.bashrc
and test the l2gen
in terminal, if it is okay, python should work as well.- Sun Jun 09, 2019 10:13 am America/New_York
