DInSAR products of Sentinel-1A/B data sets (SM/IW)

[ Edited ]

Hi everyone,

 

My usual work with Interferometric products and workflow is focused on SNAP (ESA's Toolbox). SNAP is one of my daily software I use since over a year...right now I'm trying to shift my knowledge into ERDAS imagine and it's kind of a struggle...

 

Is there any tutorial of "how to process Sentinel-1A/B data for InSAR/DInSAR products" ?

 

Even by loading the .SAFE files I got a bit frustrated, regarding there is no way to load the SAFE-Files for the Stripmap/IW Sentinel-1 data. Why is there an option to load the .xml data (metadata), and when trying to load the .xml, there is a readout issue. There is a SAFE File loader for Sentinel-2, but not for Sentinel-1?

There is a option to load the tiffs out of the measurment folder (Tiff/Tiff-direct read), but I guess I cannot access the Amplitude & Phase this way.

 

Can anyone provide any help? I checked the forum, if there is even a possibility to work with ERDAS Interferometry Toolbox combining the Sentinel-1A data, but the answers are kind of shallow. Please don't get me wrong!

 

Much appreciation

 

Phil

Hello Phil,

 

ERDAS IMAGINE 2016 v16.1 does not currently support Sentinel-1 data in the Differential InSAR tool.

 

It is not necessary to import the Sentinel-1 data to IMAGINE’s native IMG file format in order to use it in the interferometry tools. You should select the XML files found in the data’s “annotation” folder to load a swath of data from the Sentinel-1 scene.

 

The Hexagon Geospatial documentation portal has lots of information about interferometry that you should find very helpful. I would encourage you to read the Radar Interferometry User Guide which contains interferometry concepts and workflows for InSAR, CCD, Time Series CCD and Displacement Mapping (D-InSAR).

 

If you could provide me with your email address I will send additional documentation about Sentinel-1 data and ERDAS IMAGINE.

 

Kind regards,

 

Stephen Bent

Hi sbent

 

thank you for your information!

That would be need, pplease send it to philippe.ott@hexagonsi.com

hopefully a fully supported Sentinel-1A will be released soon.

 

 

Have a nice day and thank you!

Hiya. Any plans to support S1 data in the DInSAR tool? Cheers, Johnnie

Yes.

 

What application are you looking to put it to?

 

Cheers

Immediately; just a query vs SNAP for a training course I'm afraid.

Hi Johnnie,

 

That was a what, not a when :-) You should probably PM me on that one.

 

In terms of the when - Having to handle all bursts in the swath is a tricky nut to crack, so it's taking a little time. But it's being actively worked on.

 

Cheers

Thanks! What I meant was, in the short term nothing too special, but it could be interesting to some clients if it's doable in IMAGINE in a wizard based approach as it's not very stratightforward in SNAP. Ta, Johnnie

Hello Stephen, could you please send me additional documentation about Sentinel-1 data and ERDAS IMAGINE to my email (fatchurtepung@gmail.com). I am trying to do DInSAR with Sentinel-1 data.

 

Thank you
