This transformation is a spatial interpolation type. In the config there are options available that are commonly needed for other spatial interpolation transformations, but not for triangulation.
Interpolation option is always Renka-Kllein, regardless of what is in the config.
Minimum value can be configured. If it is used the output value will never be lower than the minimum value.
Extrapolation type can be configured.
number of points determines how "smooth" the triangular grid is that is created for the interpolation.
coordinate scaling factor is always 1, regardless what is configured.
CoordinateSytem is always 2.
The following config options are ignored by the transformation:
