Re: Terra LUTs causing segfault

Thanks for the instructions and for confirming that dbvm uses seadas - I might try and bolt seadas-7.5 into dbvm.

Re: Terra LUTs causing segfault

Thanks for replying. Sorry, I should have said that it's dbvm v3 (standalone, not VM) which crashes, not seadas.

Terra LUTs causing segfault

Hi The latest Terra LUTs distributed on 13 May 2018 (day 133) seem to be causing the level1 processing to fail (segmentation fault). The files are: 8040351 May 13 23:10 MOD02_Emissive_LUTs.V6.2.2.14.hdf 199874 May 13 23:10 MOD02_QA_LUTs.V6.2.2.14.hdf 10392396 May 13 23:10 MOD02_Reflective_LUTs.V6.2....

Re: Rainbows

I'm still seeing this type of artefact in polar2grid v2.0, see attachment.
Not in bright areas like previously but in dark sea between bright clouds, so it looks like a polar atoll!

Re: Drop-outs in RGB

(sorry for the delay, I didn't see the notification of your reply because it was in my spam folder!)

I'm now uploading the logs, the crefl files and the geo files to your ftp site.

Drop-outs in RGB

Hello polar2grid has been mostly working fine but occasionally the RGB will exhibit a drop-out that's not present in the individually-extracted bands. I've attached an example of the dropout (flipped vertically to match the direction of scans as seen by hdfview). Also attached is the data as seen by...

Rainbows

Hi, I'm seeing some odd artefacts whenever I run polar2grid.
It looks as though areas which are black or white are being turned into rainbows, see attachment.
Does anyone recognise this problem?

Re: VIIRS Corrected Reflectance Tutorial

I know this is going to be really obvious to most people(!) but you'll want to run run_viirs_crefl.bash separately for each and every SVM05* file in the directory if you're not using aggregated granules.
(the script does not allow wildcards and does not process all associated files given just one)

Re: polar2grid projections

I'm not sure my Cassini example is going to work - it uses the "-te" syntax from a gdal command line which is not proj4 syntax. You're going to have to specify all values rather than None. There's a helper program in the new polar2grid called p2g_grid_helper.sh. msg_672_ql, proj4, +proj=ca...

Fix rt-stps error "Failed to read external DTD"

I suspect an update to Java (I'm using the Oracle Java runtime) has broken rt-stps. The error messages are: Fatal Error: URI=file:///packages/viirs/drl/rt-stps/bin/../config Line=2: External DTD: Failed to read external DTD '', because 'file' access is not allowed. gov.nasa.gsfc.drl.rtstps.core.RtSt...
