ERROR: geogen_modis failed to produce a geolocation file

[ionutserban]

Hello.

I have installed Seadas 7.4 and ocssw procesor on Ubuntu 16.04.3.

I try to create the GEO file running the following command "modis_GEO.py -v A2016249110000.L1A_LAC" and I received the following error:
######

Does anyone has any idea on how can I solve this problem?

Thank you!

I have no problem processing the same file.  You have:

Searching database: /home/ionut/seadas-7.4/ocssw/var/ancillary_data.db, while I get

Searching database: /home/seadas/ocssw/run/var/ancillary_data.db.  Note the extra run directory in the ancillary data path.
I suspect you got the wrong OCSSW_bash.env file from NASA's server, see SeaDAS 7.4 OCSSW install on linux -- pyverchk.py not found.  Maybe a there is a glitch in NASA's time machine.

The LogStatus file indicates:
No entry for file with LID 600020
This should point to the geolocation LUT.
I'd say to try "Update OC Processors" - but even I get the error described in the link gnwii gave.

Just fixed this.  Please update you OCSSW and all should be well.

Dear Don,

I am getting this error again. And according to your suggestions, I updated the ocssw via install_ocssw.py, but it still failed. Then, I remove the all files in the directory of ocssw, and re-installed the ocssw via:
./install_ocssw.py --install-dir=./ocssw --git-branch=v7.4 --aqua --terra --verbose

However, the problem was still thrown, I don't know why, my system is Centos 7.0, could you give me some instructions?

Please rerun modis_GEO.py with the "-log" flag, then attach the resulting LogStatus file.

How did you create the input file: A2017243214000.L1A_LAC.x.hdf ?  I'm assuming it is an extract of A2017243214000.L1A_LAC.  Perhaps try the full file and make sure it works. 

Also note that SeaDAS 7.5 has just been released.  https://oceancolor.gsfc.nasa.gov/forum/oceancolor/topic_show.pl?tid=8598

Thanks a lot Danny.

Yes, the L1A_LAC.x.hdf is extracted from the full file in ocean color browser. That's exciting for the SeaDAS 7.5 release, I will updated the lastest version and then try again.

Best,
Zhigang
