PACE RGB generation

[tsm00]

Greetings,

I have a PACE related Seadas 9.0 question/problem. I am trying to generate a RBG true-color image from a level-1b granule using Seadas 9.0, Tag T2024.16. I am on a macos 14.2.1, and have python 3.12 active.

First, the installer had a problem with loading luts - the 'install_ocssw' script was defaulting to python2.7, but only for the lut installation.

Secondly, when I tried running 'mapgen':

mapgen --ifile /Users/tim/Desktop/images/PACE/PACE_OCI.20240413T175156.L1B.nc --ofile /Users/tim/Desktop/images/PACE/testrgb --use_rgb

I got this strange error message with 'dshea' in the error. It was:

line 246 of /Users/dshea/ocssw/oel_hdf4/libbin/ncdfbin_utils.c: NetCDF: Variable not found

I don't have this directory, and I think 'dshea' is a programmer for NASA, as that name appears also at the top of the 'install_ocssw' script.

I think its a code bug, but there is something weird with the original python installer defaulting to 2.7, even though my window had python 3.12 active when I ran the installer.

Thanks!

try adding '--product_rgb=rhos_610,rhos_555,rhos_465' to your command.

If I add l3bprod=rhos_465,rhos_555,rhos_610 to the l2bin command, the binning completes without error.

We replicated the error, and it seems that l2bin bailed when l3bprod was not provided.

[OB ODPS - towens]

Since OCI is hyperspectral, with an undefined l3bprod, the l2bin file has 286 binned rhos bands from rhos_315 to rhos_2258.
