Problem: Overlaying height data with images [message #3935]

Hi!
I have got height data and an aerial image (colour) from the same area.
(Both about 800 * 800 Pixel)
I want to produce a perspective view of the area and overlay the
image data to get a more realistic view of the area.

I used the SHADE_SURFACE procedure with the SHADE Keyword.
The results looked quite horrible:
Because of the interpolating algorithm used by SHADE_SURFACE
(Manual: "The shade of each pixel is interpolated from the
surrounding SHADE values") the resulting picture looks very funny,
but you couldn't recognize anything.
(I think its a combination of problems: colourtables, screen resolution,
interpolation algorithm ....)

Has anybody an idea for a solution of my problem???

Thanks

Johannes

P.S. Mail-answers preferred ...
