I discovered that water areas are not captured very well, probably due to reflections, wavelets etc.
So I need to get rid of the water areas, and replace the water with another water plane.
I have cut out the water now several times manually, with the Filtering tool, drawing boxes and lasso's around these areas. But as you can see from my top-down screenshot, the water areas are all over the place, and it takes me several hours to cut it out. (even worse: RC crashed several times during the selection process, losing a lot of tedious work; saving takes a long tome so saving a lot slows down my progress).
One solution I was thinking of is something similar to the Magic Wand tool in Photoshop: select a polygon, and the being able to select all polygons with a similar color, based on some sensitivity on the RGB color. These could then be cut out.
Of course it is possible that some polygons get selected that should not be cut out. For these, it would be good to have some Unselect tools, like an Unselect square and lasso.
If you think there are other, better solutions for getting rid of the water polygons, please let me know.
