Thanks for the compliment. The latest version of my tool is available at fsdeveloper. I have a couple of bug fixes to make then I will have a newer version.@Kelvin Richardson's tool is very powerful in my opinion. Without this tool my whole Germany and Africa project would at least not have been possible.
But Python-Script jus starts this tool, the creation of the water and blend masks makes this tool alone.
I am using an old version (I think the first he released), and was no smoothing possible yet. As far as I know the latest version also supports that.
