Generate mosaicing mistake

julianch0 · February 21, 2020, 4:28pm

WHEN A MOSAIC MADE THE RESULT IS AN ERROR

THE STEPS I DO ARE

1)RESAMPLING
2)MOSAICING ( WITH DEFAULT VALUES)
3) ERROR RESULT

I HAVE ALSO CHANGED THE PARAMETORS IN PROJECT UTM / GW84, BUT THE RESULT IS ERROR

I HAVE TRIED WITH THE MULTI SIZE -MOSAIC TOOL, THE RESULT IS THE SAME ERROR

NOTE: TRY WITH 4 IMAGES, THEN WORK WITH TWO IMAGES BUT THE ERROR PERSISTS, THE PIXELS GENERATES THEM BIG,

Hi @julianch0,

Have you tried to use the projection mode “UTM/WGS 84 (Automatic)” ?
I think that the multi-size mosaic is recommended for Sentinel 2 data.

Cheers,

Hi @julianch0,

Could you tell me the name of the products you are trying to merge so I can try locally?

Thanks,
Martino

Hello, after practicing so much I got the following results:

If I have 4 images that I want to join, I must first make the mosaic of two pairs, I would have two separate inputs with two images attached. then I would have to generate another mosaic to unite everything … crazy

the names of the products are:
