You can, at a cost.
The google map boards are flat and do not conform to any topography plus the resolution degrades the closer you get.
So in the picture above, the sea is at the same level as the land, what I have done is raise the land by 10m and then I will lower the sea to -10m. Transdem had the wellington yard covering a range between 3 and 7m so I set it at 10 to make it easier.
If at a later date Transdem is able to follow the the terrain with this type of pic then it will be the way to go, at the moment it will only do it with a terrain map.
