Sentinel 1 - using pconvert to create quicklooks of SAR imagery?

Microwave Toolbox
#1

Dear Forum

I am new to SAR imagery processing.

For S3 OLCi, pconvert can be used to create RGB quicklooks from the S3 xml file.

Is it possible to also create quicklooks using pconvert from the .SAFE file ? I tried indeed, but it did not work and I assume there is a work-around this. Thanking you in advance for your help.

Actually this should be possible.
What kind of error do you get?

Maybe you need to set memory settings for pconvert in the file pconvert.vmoptions.
Change the line

#-Xmx512m

to e.g.

-Xmx12g

RGB should be no problem, what’s not possible is to use the HSV profile like in the desktop application.

I just did this:
> pconvert -p “C:\Users\Marco\Desktop\DualPol.rgb” -f png -o “G:\EOData\temp” “G:\SENTINEL1\S1A_IW_GRDH_1SDH_20140413T034943_20140413T035012_000135_000075_3662.SAFE\manifest.safe”
And that’s the resulting output.

Hi Marco

Thanks again for the great service support and prompt reply.
Before posting that note, I did try several times and looks like I wasn’t too far off.

However I am unclear about the product: DualPol.rgb. How is this defined?

DualPol.rgb - This is the RGB Profile.
I’ve stored it from the desktop application. In the ‘Open RGB Image View’-Dialog select the profile you like to use and then save it to disk. This file can then be used with pconvert.

Are you not happy with the quicklooks in the products themselves?

Hi Marco

Obviously. I should have known, it does seem logical now.

Thanks a lot. This was very useful.

No - no big fan. They give a general idea but we can do better. Apologies for the much delayed reply.
