Problem with MASK MANAGER

Dear friends

I am watching some videoes related to Mask manager in
this site http://step.esa.int/main/doc/tutorials/snap-tutorials/
, I am using some data related to SENTINEL1 like this: S1A_EW_GRDM_1SDH_20160416T051303_20160416T051408_010842_010393_702C

I am doing all the steps like video’s Mask manager https://www.youtube.com/watch?v=mIOYXbMouq4
but I do not know why my mask manager is empty!!!

What can I do know?

Cheers,

Marjan

I’m not very familiar with S1 data, but I think you don’t see masks because there are no mask defined by default for this kind of product. In the video tutorial a MERIS product is used. This one has masks defined by default.
But you can create your one masks as explained in the tutorial.

Yes, the S1 products do not have default masks in the product. You can import vectors from shape files or create your own polygons and then use them as masks.

I still have the same problem in SNAP 5.0 (SNAP Desktop/Engine implementation
version 5.0.4) with Sentinel-1 Interferometric Wide swath (IW) images.

It seems that the multi-resolution nature of Sentinel-1 causes the problem.
See for example:
https://senbox.atlassian.net/browse/SNAP-729

I think the internally created mask has product-width, which corresponds to width of the
Deburst-image for Sentinel-1 IW. So you will never see this mask within one of the separate
IW1/IW2/IW3 Bands.
After creating a Deburst-product (Radar/Sentinel-1 TOPS/S-1 TOPS Deburst), the Mask Manager
was filled as expected.

Dear all
I also have the problem with mask manager.
I create a mask using polygon, and can use it to do statistics. I can also apply it for the other products, but failed to export it.
