Surfaces generated by noninterpolating moving total least squares method

In this paper we suggest a method for generating a surface approximating the given scattered data. The method is based on smoothing the data by using the moving total least squares method. We determine a global approximating function by first forming, at each point, a local approximant (local plane) in the sense of total least squares. In this way it is taken into consideration that errors occur in all data coordinates. The method is tested on several examples.
