Thanks Wolfgang, Martin.
That's it! Pixels, not percentage! Problem solved.

And no, my sketches are not hidden below the surface bitmap, today was my
first attempt at that, and I have produced many many plan maps, and never a

I take you mean if I enter some grid data, even zeros, I should get a (flat)
terrain model in loch?
