Until we fix this, you can grab the file from here:

The bug that you are seeing only happens when you use the north,south,east,west parameters. The bug was introduced between V2021.1 and V2021.2. It was fixed in T2021.11 and later If you do not want to install a newer version of the code you can - run lonlat2pixline to find the spix,epix,sline,eline ...

If you have installed a sensor using the SeaDAS GUI or install_ocssw, the aerosol LUTs will be in:

$OCSSWROOT/share/<sensor>/aerosol/*

Hope that helps.

Thanks George,

I get the same core dump when producing sst_tripple on a MODIS file. We will enter a bug report. L2gen should catch products that can not be produced and print out a reasonable error.

Actually I had to fix a few things in the CMakeLists.txt file. You will need to use "--tag T2021.23". You will not be able to build the VIIRS code so do not turn on the BUILD_ALL or BUILD_VIIRS_L1 flag for cmake. The process becomes: export OCSSWROOT=/home/colapao/seadas-7.5.3/ocssw instal...

I would suggest not building the VIIRS part for now. I have to make a few sets of libraries to export for that to work. Try this:

Code: Select all

cd /home/colapao/seadas-7.5.3/ocssw/ocssw_src/
rm -rf build
mkdir build
cd build
cmake .. -DBUILD_VIIRS_L1=OFF
make -j 20 install

Let me know how that works.

All of the programs you mentioned read the product.xml file. Here is a minimum product entry: </product> <product name="my_new_product"> <units>m s^-1</units> <category>Derived</category> <range> <validMin>0</validMin> <validMax>50</validMax> <displayMin>0</displayMin> <displayMax>20</disp...

Yes, the n,s,e,w params for l2gen are more convenient than grabbing the output of lonlat2pixline. I am almost done fixing the bug. Expect the fix in the next release.

Thanks again for finding this.

OK, looks like the n,s,e,w params for l2gen processing VIIRS has a nasty bug in it. Here is what I suggest for your processing stream. - run lonlat2pixline with the GEO file and n,s,e,w to get start/end, line/pixel for region of interest - run l2gen with L1A and GEO file and start/end, line/pixel pa...

I can reproduce the seg fault on my Linux machine. Seems to work fine on my mac, but that is how these memory issues usually behave. There is an easy work around that you can put into your processing stream. l2gen works fine if you use an L1B file as the ifile instead of an L1A. Using the example fi...
