Methods of local and spline approximations for digital processing of geomagnetic observa-tions are proposed for consideration. Algorithms for calculating piecewise-linear, sinusoidal and polynomial local approximation models have been developed. An algorithm for calculating the spline approximation model is developed. The generated mathematical apparatus is focused on solving problems of parameter estimation, filtering and spectral analysis for geomagnetic observations.
Keywords: local and spline approximations, models, geomagnetic observations, digital processing.
