I was wondering what’s the best practice to work with multiple tiles of L2A images?
I would like to extract all layers of multiple L2A images (many dates) as GeoTIFF for a area of interest (AOI) which is partly covered by 4 different tiles. Before the product format changed (somewhen in september?) it was easier for me, because the AOI was covered by one single product.
So what I tried to do right now is:
1.) L1C -> sen2Cor -> L2A for all tiles and dates
2.) Resample all L2A tiles to 10m resolution
3.) Create a mosaic of the 4 tiles ( SNAP was complaining about “multi-size product” even though I resample in advance) for each date
4.) Extract AOI by subsetting each mosaic
5.) Export as GeoTIFF (same error appeared like in step 3, did not happen in a earlier version of SNAP)
Is there any better/faster solution and does anybody experienced similar problems with SNAP (newest version) complaining about “multi-size products” even though resampling was done?
Thanks a lot!
