how to get AOI ard result from overlapping scenes about opensartoolkit HOT 3 CLOSED

Hi Jiankang,

are you just using 1 scene per track? Then you could check the Orfeo Mosaic Tool (otbcli_Mosaic on command line).

Open SAR Toolkit is really about batch processing, and for most applications it makes much more sense to consider time-series instead of single images. So if you want mosaics, you just get them after the time-series processing, and I never tried to process 1 image per track in a time-series, but maybe that works?

Hope that helps,
BV

@BuddyVolly Maybe another question about my mosaic result, I use gdal to mosaic the two processed RGB tiff tiles. And the result is like this:

I find that in the land area the value change between these two tiles are small, but it is very obvious in the sea area. Is it normal or how can I avoid this problem?

For processing the tiles I use

s1_grd.grds_to_ard(
    inventory_df=s1_grd.refined_inventory_dict[key], 
    timescan=True, 
    mosaic=False, 
    subset=s1_grd.aoi,
    overwrite=True
) 

Thank you!
