Your setRange's must include the actual ranges of east,
north and height values. If you want 'no scaling' then
you should expand some of the ranges to make sure that
all the ranges have the same size. That is:
eastMap.setRange(3532000.0, 3533000.0);
northMap.setRange(5379000.0, 5380000.0);
heightMap.setRange(0.0, 1000.0);
So the range of all is 1000.0. The surface will look very flat.
Cheers,
Bill
