Stack imagen Sentinel 1 and imagen sentinel 2

Continuing the discussion from Image Fusion Using Sentinel 1 and Sentinel 2:

My objetive is to merge the two products
I just pre processing the SAR data and the optical data like your instructions with SNAP, but when I create a Stack I receive that error message when I upload both products:

Maybe the problem is that this is not the procedure to fusion this type of images?

is the S1 product already terrain corrected and projected to the same UTM coordinate system as S2?

If so, select “Product Geolocation” in the second tab instead of “Orbit”

I make this steps: Apply prexise orbit file > S1 Remove GRD Border Noise > S1 Thermal Noise Removal > Calibrate > Multilooking > Speckle Filterin > Terrain correction. at the end I get this image:

then I have applied the Coregistration, choosing as products the image s1 with an image S2 of the same date. I have obtained this image as the final image:

My question is, have I merged them correctly? Is this what it should look like?

yes - looks good!

You can play with the contrasts of red and green in the color manipulation tab to enhance the different color tones. Currently, the image tends to be greenish.

It is advisable to convert the Sentinel-1 backscatter to dB scale for a more gaussian distribution of grey values.
