Re: LaPalma eruption animation using EUMETCast data from EUMETSAT.

Ernst Lobsiger
 

Dear All,

this is a simple BASH script plus an ffmpeg one-liner. The idea is that you have all frames (I use *.jpg images) preprocessed in a directory. In my case the frame images must be in timely order. If not you can use a "touch" first and give them the timestamp according to the slot time. The script then uses a scratch directory to make symbolic links to these images with typical link names frame-000.jpg, frame-001.jpg, ... ffmpeg finally assembles these linked frames to a video of your joice. There are myriads of ffmpeg command line switches, I'm not an expert :-\. I normally make *.ogv videos as these can directly be started from a WEB server by double click in FireFox or MS Edge. And BTW *.ogv codec is a free format not impaired by software patents. But of course, once you have ffmpeg installed,  you can also make *.avi, *.mp4 or whatever you prefer.
 
I process everything on my GNU/Linux receiver. For Windows users it should be rather easy to translate the video generation to a CMD script (maybe without my possibility of making rolling videos of the last -m xxxx minutes).

I updated the LaPalma videos with composites "ash" and "dust" and also made *.mp4 versions (I normally don't use video players. I hope *.mp4 falls under what David called "... a standard video format?" :-). I attach the scripts I just used to make those videos. You find the files under "images + movies" on my oldest and weakest TC receiver.

http://5.153.116.236:85                                            (Internet has become a bad place for online services, this link will not stay open indefinitely ...)


Happy hacking,
Ernst

P.S. Even with all the extra load from LaPalma my GNU/Linux TC receiver didn't miss a single UDP packet ...

Hi Ernst

That is very impressive

Do you think you could upload the python script that you used to produce that - it would be very useful

Very impressive, Ernst!

It clearly shows the benefit of 10-bit data, and the 5-minute steps from the
Rapid Scan Service!

Any chance you could make that available in a standard video format? I used
GIF simply because I knew Twitter would accept that, and the file was only 3.8
MB. Maybe an MPEG might be better?

Re: EUMETSAT Data Policy / Did I miss something ?

Ferdinand Valk
 

Ernst,

 

Your reading of the policy is correct.

If you use material older than 3 hours (your last frame in an RSS clip), usage is granted without license fee. A couple of years ago this was not the case. The revised Data Policy document was then released without informing registered users.

As I use the data without latency, the Service Provider license fee still applies.

 

Cheers,

Ferdinand

Dear All,

on this rainy day I read the latest version of the "EUMETSAT Data Policy" (PDF) found here:

https://www.eumetsat.int/legal-framework/data-policy

I remembered that Meteosat Seviri "Hourly Data" as well as Metop AVHRR data have been
"Essential" and thus free for any purpose (including data redistribution) for quite a while.

What I never had payed attention to are all the text paragraphs that are talking about
"NON-Essential Data"  with a "Latency" of more than 3 hours. If I understand the text
and "Latency" definition right I can publish a 15' or 25' RSS composite image I processed
from Seviri data that is at least 3 hours old (no original data may be published though).

I also checked EOP and put my findings in the "EUMETSAT Data Licensing.txt" file attached.

I finally found on the EUMETSAT site this page that clearly seems to confirm my findings:

https://www.eumetsat.int/eumetsat-data-licensing

It means in short that I can publish any RSS video (e.g. processed with PyTROLL/Satpy)
provided it ends with a last frame that is at least 3 hours old. Am I just dreaming!??!
I can't remember that this understanding of the Data Policy has ever been discussed here.

- Can anyone confirm that my interpretation of the rules for > 3 hours old TC data is correct?
- Has anyone asked OPS about "NON-Essential Data" with latency of more than 3 hours before?


Best regards,
Ernst

Re: Tellicast Reset

geojohnt@...
 

Enzo,

As David has said there isn't a definitive answer.
It all depends on your computer specification and whether you use a one computer receiving/display computer, and how many 'receive'/display programmes you are running and how much data you are receiving and processing.

I use a 1 m dish, Inverto Black Ultra quad LNB (the other ports go to satellite TV receivers) and an SR1 receiver and a single computer for 'reception' and processing.

My TP 1 SNR goes from ~ 14.2 to ~13.7 dB over a 24 hour clear sky period.

The computer has an Intel core i5 4690KCPU @ 3.5 GHz.
16 GB RAM.
1.81 TB HDD - used for EUMETCast only.
111 GB SSD used for Windows and 'other' programme storage.

Windows 10 Home 64 bit.
And an NVidea GeForce GTX 7500 Ti graphics card (not really necessary for EUMETCast).

I have a RAMdisk of 997 MB from a 'previous system' but I do NOT use it.

I run 3 X MDM, 2 X GOES ABI, Himawari Manager, 2 X Metop Manager, 1 X Animation Manager, 1 X AVHRR Manager and SR! Controller.

I get yellow and red TC icons every now and again (especially if I'm watering pot plants in front of the dish) - but the data doesn't stop - look at the graphs and you will see data flowing even when the TC icons are 'coloured.'
Well, if the SR1 Controller is Locked and showing Traffic flow.

These are just warnings and you have been informed to just click on reset to clear them.
I'm a bit lazy and sometimes just leave the TC icons 'coloured' till I can be bothered to open up TC and clear the warnings.

I run 24/7 and get quite a lot of Missed Packets before FEC and not that many FEC Recovered Packets over a period of time - but I seldom see any problems with the images.

I have software running that automatically defrags my HDD every now and again.
I DO NOT KNOW if this is really necessary for EUMETCast - so perhaps others could answer this.

When I get a bit of time over winter I'll experiment with using my old RAMDisk - but as things seem to run OK at the moment and have done for ages - I'll probably leave things as they are.

"If it ain't broke - don't try to fix it!!!"

Regards,
John.

Enzo,

I don't know the answer!  There isn't one.

- On one system I receive HVS-1 (alone) sending to a separate 1 TB DATA disk,
no losses. PC Kiruna.

- On two other PCs I have a RAM disk for the TMP file alone, both receive and
process.  PCs Alta and Stamsund.

- On another system (HVS-1 and HVS-2) I have a RAMdisk for TMP (HVS-1) and TMP
& receive (HVS-2).  PC Lund

- On two other systems I have RAM disk for TMP and \received files, BAS alone.
  One is receive-only, the other receive and process.  PCs Penguin and Harstad.

So generally I suggest a RAMdisk, especially if the PC is doing more than just
receiving EUMETCast.  The ideas have grown and changed over the years.

If you need to reset TelliCast manually - to continue data gathering -
something is very wrong. If you mean that you need to go into the HTML
Shell to reset a yellow or red indication that is completely normal.

As to what is causing the issue, we found a long time ago that an excess of
CPU, network, or disk activity could upset the operation of TelliCast, and that
using a RAMdisk for either the temp or the temp and received files could
ameliorate the problem to a great extent.

This has all been written up in the GEO Quarterly and on my Web site, and
the temp & received solution has been extensively discussed here.

David

TelliCast will normally reset itself.  Open the HTML Shell, Click on the

Warning or Error text (next to the Status on the top line), and discover what

caused the error.

Enzo,

It's not a question of "correct" or not - it's simply what options you consider appropriate for the data you are plotting. The Options would be different if you were plotting memory usage or CPU temperature. You can have an "options" setting for each set of data you plot. So, for example, if you are plotting the network I/O for an SR1 you might have a section:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#---------------------------------------------------------------
# SR1 - "Traffic LAN" output
#---------------------------------------------------------------

Target[SR1-Traffic]: 1.3.6.1.2.1.2.2.1.16.1&1.3.6.1.2.1.2.2.1.16.1:public@192.168.5.55
MaxBytes[SR1-Traffic]: 150000000
Options[SR1-Traffic]: bits, unknaszero, growright, noo
Title[SR1-Traffic]: Ayecka SR1 Traffic LAN
PageTop[SR1-Traffic]: <H1>Ayecka SR1 - Traffic LAN (Edinburgh)</H1>
<TABLE>
<TR><TD>Interface:</TD><TD>Ayecka SR1 Traffic LAN</TD></TR>
<TR><TD>Max Speed:</TD><TD>1 Gbit/s</TD></TR>
</TABLE>

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Note that the "Target" line has split in the example above, and you would need your own SR1 IP address. Note also the blank line after "PageTop" entries. Here the "Options" are:

Options[SR1-Traffic]: bits, unknaszero, growright, noo

Look in the reference manual about these options.

https://oss.oetiker.ch/mrtg/doc/mrtg-reference.en.html

I hope the guide will answer any other questions you will have, together with all the examples I have provided on my Web site.
