I am trying to mosaic 42 remote sensing rasterstacks (with 250 bands) based on the criterion that in overlapping areas, the pixel should be taken that has the most nadir viewing angle

Beside my rasterstacks I also have 42 rasters (so one for each stack) with the corresponding viewing angle for each pixel.

Any idea how to solve this?

I tried to include the viewing angle raster in the stack, and use something similar to

mosaic(a,b,fun=function(x)(min(x[[251]]))

but that didn't work...

Any advice?

Thanks in advance,

R.
