John,

the iceberg first turned CCW a little and is now spinning CW.
I have put six videos on receiver Io (Pytroll/Satpy + ffmpeg).
All *.ogv run in browsers like Edge and FireFox as players.

Richard,

welcome to the Club. Stay with GNU/Linux whenever possible! I do all my development there. Much more versatile and performant.
You find a very old HOWTO for GNU/Linux below. It has never got much attention and is certainly deprecated. Only with the Windows
HOWTO V1.0 (one good thing out of the first Corona Lockdown) I tried to make things more simple and less technical. Maybe you still
find a couple of ideas below. When I will issue a V2.0 for Windows towards the end of 2020 I will also publish all my scripts for GNU/Linux.
All this is also based on Miniconda3 for a better synchronization with Windows 10 even if we have other possibilities under GNU/Linux.

Stay tuned,
Ernst

Ernst,

Having followed this thread, I decided that I would  have a go at Pytroll/Satpy.

As I already had a Conda installation on a Linux Mint machine, I elected to try it there and eschew Windows for once.
After following your HOWTO instructions very carefully, I managed to produce an MSG-4 composite image reasonably quickly
so I now have a working installation.

There is still a lot to learn but at least I am on my way and thanks for the beginner instructions.

Regards,
Richard


Course of A68

I attach an image of today with the sea floor profile next to it. It has all
the looks of it that it is following this profile with the local current,
maybe thus avoiding stranding after all?

Graham,

scripting is certainly possible (though out of range for most users here). You might remember that the next things a script would check is for Sentinel-1A Decemebr 19th and for Sentinel-1B December 21th. But A68a is a moving target and considering its speed also might slip out of an automated fixed search window soon. Makes scripting not easy ...

Ernst

Hi Ernst

Thanks - I have managed to do that :-)

Its just not the level of automation that I was looking for

All my scripts run on a schedule in Task Manager so if Im not at the computer I still get images

I was hoping to do the same with Sentinel 1 data but it seems not

Graham,

Here is the Windows way: Go to the hub and spot South Georgia with the mouse. Then enter in the search window what others found for you ...

All,

Quite a change in orientation since December 9th and today seen in attached Metop images via EUMETCast.

Re: A68

Hi Ernst

I have done that.

What I was trying to do was to automate the process so that I could run a script that would download the files for me on a schedule

It doesnt seem that I am able to do that as there doesnt appear to be a consistent product id - it changes

So back to the Hub GUI

Regards

Graham

How to you find the files
Graham,

it's the old story when David says "Windows users want fast results ..." and I say "You have to RTFM ...".
The fastest way to get the latest files is to go to the hub GUI and copy and paste the filenames above
into the search line top left. The scientfic way is to read Sentinel-1 manuals and skim sar-c_safe.yaml.

Cheers,
Ernst

Hi Graham,

 

I use the Open Hub at https://scihub.copernicus.eu/ because this offers precisely the same data as the Api hub for scripting, it gives me more freedom to choose my ROI and change dates etc.

I’ve used scripts in the past but haven’t already for a considerable period of time. Btw, I suppose you are aware that you can also save your search criteria on the Open Hub?

Hi Ferdinand

How to you find the files

Do you use the Sentinel Hub GUI or do you use wget

I have tried to use wget but without success - it seems to want a product id and I cant seem to find it

Ernst,

Both resolution sar files of today are available.
S1A_EW_GRDH_1SDH_20201215T072534_20201215T072634_035693_042D26_F2A2.SAFE

Excellent detail .
By the way, if you follow the bathymetric profile of the area it might well
be that the berg may slip around the island from the lower side. Or break up
first of course...

Cheers,
Ferdinand

Ernst,

 

I just noticed that I totally misread what you meant. You referred to the legend at left and not the receiver path. Changed it now altogether to <attached>.

Yes Ernst, the TBS 6903 runs under Windows 10 on a separate PC and I have the code pointing to the network address. The 6903 hasn’t failed me yet, so there was no reason to switch-over to an update newer version. When more transponders will become a reality I’ll probably be upgrading.

 

It will be a good break of lockdown routine when the HowTo V2.0 will see the light! I’m looking forward to it.

Ferdinand

Ferdinand,

yes, very nice too. Maybe you want to change the receiver string in the code. Or do you run a TBS-6909X under Windows 10 already ... :-).
I have now a couple of new scripts including MultiScene stacking images of Sentinel-3A and Sentinel-3B for better daily coverage. I hope
to issue them all as a package in a Version 2.0 of the Pytroll/Satpy HOWTO towards the end of the year (@Graham, you will have to wait too...).

Hi all,

I will update the animation on a daily basis at the same link:
A68 Animation

Folks, that are interested in, can have a daily look on the way of iceberg A68.

The images are processed with Eumetcastview. Thank you Hugo for providing your excellent software.
The animation is processed by ImageMagick.
