make command error when building ocssw binaries

How did you get the lib3 source files (ocssw/opt/src)?  When using the SeaDAS 7.5.3 GUI or the install_ocssw.py script you will get proj4 version 4.9.2.  It is true that our latest in-house development code is using proj version 7.0.0, but it is strange that you have that version using ins...

Rrs_556 not found in default product list?

Barry,

My first guess is that since smigen is deprecated it does not know anything about JPSS.  It is probably using the wavelengths for NPP which has 551 instead of 556.  Might I suggest using l3mapgen which is what the production system here uses to make SMIs.

"/home/seadas/ocssw/src/l2bin/l2bin.c" is where the source file is located on the computer at NASA that made the binary.  The normal install of OCSSW does not install the source files.  You can install the source if you would like, but they are not needed to run the binaries.Runn...

l2gen products

All sensors that l2gen can read are supported by lonlat2pixline.  Both programs share the same sensor reading code.

It is easy on the command line also.  Assume you want to run l2gen with ifile=A2008080195500.L1B_LACgetanc.py A2008080195500.L1B_LACwhich will create the file A2008080195500.L1B_LAC.anc  Now use the ancillary files in l2gen:l2gen ifile=A2008080195500.L1B_LAC geofile=A2008080195500.GEO ofil...

Problems building SeaDAS

Looks like we needed to add the date_time module to boost.  Add "date_time" to the build line of:

$OCSSWROOT/opt/src/boost/BuildIt

Make line 25 look like this:

./bootstrap.sh --prefix=$installdir --with-libraries=chrono,filesystem,timer,date_time

Then run the boost/BuildIt script

What is the processing flow for VIIRS for L0 -> L1 -> L2 -> l2bin -> l3mapgen

If you are grabbing the L1A files from us, you might as well get the GEO files from us also also.  Dealing with the L0 files is more difficult, and we do not distribute the L0->L1A program.L1A:V2020078180000.L1A_SNPP.ncV2020078185400.L1A_JPSS1.ncGEO:V2020078180000.GEO-M_SNPP.nc  V202007818...
