Thanks. I will try this. I was hopping that I can crop L1 image! That way I can save some time in converting to L2. But I also see from some of the earlier comments in the Forum that for reprojection of L2, entire image has to be there and can't be cropped! Is that right?
Thanks again.

Hello,  Ah yes! I closed the file and now I can open it! Thanks so much for your help. I truly appreciate it.  I have a question for l2gen  processing (on Linux using command line). I have a series of OLI, MSI, OLCHI L1 images that I am trying to convert to L2 using l2gen. These data ...

Hello,  I generated OLI, MSI, and OLCI L2 products using l2gen on my linux machine and saved output files in NetCDF formate. Then I reprojected these files using SeaDAS GUI. I chose WGS84 projection and nc as the output data format. I got reprojected nc files but when I try to get ncdump, I get...

Thank you for the suggestion, Sean. I will look into that. So when I use 'reproject' from the GUI, does it do any resampling or binning? How to decide that factor?
I am grateful to all of you from this forum for patently helping with these questions.

Hello, Thank you for the link to the 'gpt cookbook'! I have never used this before!I am wondering what projection does the l2gen output file have. There are lat-lon values with each pixel.For gpt.sh I am trying to follow Example 1  shown in the 'gpt cookbook'.  I am not sur...

Hi Don,   Great! thanks very much for your reply. It worked fine.   Another question I have is about re-projection of l2gen output. I want to get the output file (which is .nc by default I believe) in WGS84/Geographic projection. In the GUI I just use the reproject option.  ...

Hi Sean,
    I ran l2gen for OLI - but I am sure it used the climatology data. On the GUI it is simple to select 'Get Ancillary' but I do not see how to set this  in command line parameters.
Thanks.

Hello,  I have a few  questions about processing MSI and OLI, converting L1 to L2 with l2gen on a Linux machine.  I have used SeaDAS/OCSSW from the GUI so far to get chlor-a from MODIS and OLI and have recently moved to using Linux - with command-line options. This is because I want t...

Thanks so much for your reply. I tried running l2gen in bash and it seems to be working! At  least I did not get the error - and the program is going through
execution steps!
Thanks again.
