Good Evening,
If You want to get rid of the white areas you do -dstalpha in the penultimate
gdalwarp step.
That setting is to get all the areas outside to be transparent when You warp.
gdalwarp -t_srs EPSG:3857 -overwrite -multi -wo NUM_THREADS=ALL_CPUS -dstalpha
-wm 1024 -tr 169 169 --config G
Good Morning,
I have a stackoverflow on this issue if anyone can give some info. It turns
out that if you force the resolution in the warp, the resulting file does
look good.
