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 ...

Cheers,
Ernst


Giant iceberg A-68A is spinning.

All,

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

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
S1A_EW_GRDM_1SDH_20201215T072534_20201215T072634_035693_042D26_8647.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.

 

Cheers,

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.

Re: pity

That is indeed a very good one Ernst.

Using ‘true_color’ instead of ‘ocean_color’ brings the image out a bit better still.

Ferdinand,

this should be the next good (+6 days) from December 9th:

S1B_EW_GRDM_1SDH_20201209T072535_20201209T072635_024622_02ED88_4503.zip

so expect Sentinel-1A today (might be already on the hub, have not checked yet). Meanwhile
have a look at the wonderful image of Sentinel-3B from yesterday. I have not many of those.

Cheers,
Ernst

As it turns out, precisely the "perfect" HiRes Sentinel 1 slot of December
14 that should bring both South Georgia and A68 into one frame is missing on
the Copernicus hub. Maybe delayed in distribution, but strange nonetheless.

Ferdinand


Eumetcastview, xrit2pic doesn't processing NOAA 20, NPP data

Giftmacher
 

There is over 7 GB data  from NOAA 20 and same from NPP, both programs doesn't "see" it. Is there something to do with it?


Re: A68 continued

Ferdinand Valk
 

Ernst,

 

No no no, maybe I do advance a bit but not as much as you assume. Let me explain.

 

First the 1SDV (full name S1B_IW_GRDH_1SDV_20201211T070838_20201211T070907_024651_02EE71_2FF6.SAFE) was downloaded from the Sentinel hub. It was first run with the unmodified sarmicro script and the debug indicated that it couldn’t manage the data files due to sar-c_safe. I tried to see where things were running off-track within sar-c_safe and came to the conclusion that it didn’t like the DV polarization. So, just to test I altered DV to DH and to be consistent the vh/vh in the xml names to hh.hv.

Then the file was properly decoded albeit with wrong colour assignment. But at least it decodes. Next step is to see if this can be properly included in sar-c_safe which most likely is as yet out of my league, but I’ll try anyway.

Just for fun I attach the 1SDV image (8000x8000) immediately after decoding and prior to any editing.

 

Combining I did NOT do via Multiscene but a quicky via Photoshop, which was simple as I had used the same projection for the three base images. So you did give me more credit than I deserve.

 

Really looking forward to tomorrow!

 

Cheers,

Ferdinand

Ferdinand,

you advance in stunning speed. When I combined 2 GRDM files I could only do that with MultiScene.
Your image looks like MultiScene where you stack ("blend") a list [] of scenes. So here my questions:

Where did you get the 1SDV file from?
Can it also be read with  reader 'sar-c_safe'?

Best regards
Ernst

There is now an S1B GRDM from yesterday December 13th. Didn't check GRDH, not enough memory.
Tomorrow 15th we should get an S1A GRDM/GRDH image that covers South Georgia and A68a again.

Hi Ernst

Thanks

This is the script I am using but its not finding any files

c:\Tools\Wget\wget --user **** --password *******  https://scihub.copernicus.eu/dhus/odata/v1/Product(S1A_EW_GRDM_1SDH_20201203T072534_20201203T072634_035518_042716_6F8E.zip)

Its connecting OK but I suspect the path might be wrong but Im not sure of the correct one
