Creating RGB image

[reza9095]

How the RGB image is created from separated bands (not metadata file) in SNAP? In other words, how three separated bands is integrated into one file?

The RGB view is just a visual thing, the original product is not altered, nor is a new product written on your drive. If you want to store the color information permanently in one raster you can select
File > Export > Other > View As Image > GeoTiff with geoinformation

I mean in SNAP, is there a tool such as "layer stacking" in ENVI?

RGB composite from individual bands

Sorry, i think i have not explained properly. The steps should be: Open every image/band in SNAP: File->Open Product… At the end of the process you will have 3 products in the product explorer. Raster->Band Maths… : select as target product the first one for example and in “Edit expression” you choose the band of other product [image] At the end of this process you should have two of the three bands in the first product. [image] Repeat the step 2 to add the other band to product[1] Right-…

Yes, several
Raster > Geometric Operations > Collocation
Radar > Coregistration > Stack Tools > Create Stack (also works for optical data)
Radar > Coregistration > Coregistration (works best for radar data)
