Is anyone here successfully running Idepix.olci with S3 scenes?
This may be related to the issue here, where IdePix.olci runs overnight, consumes all the RAM, but doesn’t produce anything: Sentinel 3 IDEPIX mask in snappy
I’m not using python just the SNAP GUI. When I load an S3 scene and run IdePix, it returns results fairly quickly. If I then try to display a cloud mask, nothing happens - the progress bar runs for a few hours before I kill it.
I’m running the latest SNAP as of today (6 Feb 2020).
System:
Linux geus3064linuxwsm 4.15.0-76-generic #86-Ubuntu SMP Fri Jan 17 17:24:28 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
You tried another scenes also or just this one? I’ve observed that indeed on some scenes idepix it’s just crazy but i don’t think it’s something that applies in general. Can you provide the scene whole id to download it?
It does work in snap GUI on most scenes. But the same scenes where it works in the GUI it does not work on GPT - it just hangs. Have you gotten Idepix to work with gpt? I can provide a scene and a GPT xml if that helps…
To be honest I didn’t try to use Idepix with gpt. I will try now on my laptop and tomorrow at the office. I will update you as soon as possibile. I’ve got some error with displaying IDEPIX masks too but just for some scenes.
For the latter, I’m running this on scene S3A_OL_1_EFR____20180816T104417_20180816T104717_20180817T144146_0179_034_322_1800_LN1_O_NT_002.SEN3 and with the following XML file for GPT:
Thanks for the additional info. We are looking into this issue. Actually in v7.0.0 of Idepix-Olci was an error which caused the problem you describe. With the update to Idepix-OLCI 7.0.1 it should behave better.
We’re checking this.
I tried the .xml proposed by Ken also on two PC’s. The weakeast one would just stop when all the resources were 100%. The one with a proper configuration just stopped after 5 seconds with some long error. The Idepix.OLCI is 7.0.1 version. I attached the files with the error and the .xml graph used.
@GeorgeB
You must have a strange/corrupted SNAP installation.
Your error log contains pointers into the source code which doesn’t exist anymore.
Maybe you reinstalling SNAP and Idepix can help.
We let Idepix tun and it works well on Windows. On Linux, there is an issue. When cloud shadow detection is enabled, it runs very slow. Without cloud-shadow, the processing is done in a few minutes.
@mankoff
Ken, maybe it is an option for you to disable the cloud-shadow detection.
Change the idepix node in your graph to:
Thanks Marco. I will properly configure the SNAP on the other PC. It’s not mine and in the first time I won’t get how it’s corrupted cause on snappy and GUI works just fine. Thank you very much for all the answears.
And the CPU keeps churning but nothing else happens. If the reproject node is removed, gpt runs fairly quickly. We’re using the following XML. Do you have any suggestions how to get Idepix to work?
I have a very similar issue. However mine seems to come from the cloud buffer computation. When I turn cloud buffer computation off everything works as expected. So that’s also my workaround for the moment.
May you let me know whether that works for you too?
Nope - this doesn’t work for me. I can run IdePix w/o cloud buffer, shadow, reproject, or per-pixel geocoding, but disabling reproject and ppgc isn’t an option. We’ll wait for a working idepix implementation.
I am running into problems with Idepix as well, for me SNAP immediatelly crahes when I try to run IdePix, whether i try to run it directly or import it in a graph. I have a Linux OS with all updates installed and I have even reinstalled Idepix again just to check. On Windows the process sees to run through but takes very long time to complete if run directly. In graph it also fails. Any ideas why this could be?
Hi, Marpet
When I use python to call .xml to process S3 data, I get an error: SPI not found for operator"Idepix.Olci".
When I checked SNAP, I didn’t find the idepix.olci plugin either, how do I download and install this plugin please?
