Question: how to use code to run l2gen correctly

Re: how to use code to run l2gen correctly

Can you do

Code: Select all

seadas_info
and share the result here?

Is your Mac with M1/M2 chip? If so, you need take extra steps to set up the environment in order to run l2gen https://seadas.gsfc.nasa.gov/downloads/

Or you can try to run l2gen using Client Server model (docker is recommended)

Re: Processing Landsat Collection Level 2 images through l2gen

l2gen needs an L1 file as the input (e.g. LC08_L1TP_015033_20220329_20220406_02_T1_MTL.txt)

Re: Issue w/SeaDAS 8.4 install

I just tried seadas-8.4.0 on an old mac (Monterey 12.6.5). It works fine.

Make sure you don't have another copy of SeaDAS opened. And this might help

Code: Select all

rm -rf ~/.seadas8

Re: Can not open nc data files in ODV

I don't know about ODV software, but I know SeaDAS cannot read l3b files. https://seadas.gsfc.nasa.gov/ However, if you use l3mapgen tool to turn l3bin files into l3m files, SeaDAS can read it. https://seadas.gsfc.nasa.gov/help-8.4.0/processors/ProcessL3mapgen.html Or you can download and read the e...

Re: Windows users OCSSW error inquiries

If you choose "docker" instead of "virtualMachine" for OCSSW Location, you should be able to get rid of the red warnings. However, SeaDAS 8.4.0 is not able to print out the detailed info of ocssw that is installed through docker. Instead, you can run this command on the docker te...

Re: l2gen GUI display nothing

Could you please give SeaDAS 8.4.0 a try? Also install OCSSW (the latest tag is V2023.3) through Docker https://seadas.gsfc.nasa.gov/client_server/

Re: An error message generated during geofile processing with SeaDAS

I have Ubuntu 20.04.6 LTS

I can't replicate your error running

Code: Select all

modis_GEO A2010283180500.L1A_LAC
If the generated GEO file is of the similar size of the GEO file on our site, and can be used for modis_L1B and/or l2gen, you probably can ignore the error message
