I have points that z values are close (for example: 7m, 7.5m, 8m... step
0.5m).

When I set Output Contour Interval of the ContourGenerator to 0.5, it failed
"CONTOURGENERATOR(SurfaceModelFactory): SurfaceModelFactory: Fail to set up
the Surface Model. A minimum of 3 points are required for the Surface
Model."

If I set to 1, some contours are generated, but many points that have
interger-Z value are not belonged to any contour.

I usually set value of "Surface Tolerance" same as value of Output Contour
Interval parameter.

Please advice.

Thanks

Can you elaborate a bit more on the result and how it isn't what you had
in mind?

One common problem with automated ways of generating contour lines is
that towards the edges of the DEM, especially if it's irregular in
shape, the lines can behave odd.
