There is a sloping surface.
I have made a projection on the XY plane.
I would like to get the ‘vertical’ distance between the surface and the base plane XY, and plot it in something like a heat map. (colors represent the vertical distance).
In the heat map there should be a difference in colour for the location where the vertical distance is
larger than > 2,0m (green)
less than < 2,0m (red)
