Do you want to replace the current representation of the earth shape by a spheroid with a hopefully more accurate representation which is formed by the outer surface of many concatenated spheres of various sizes, a la Metaballs? POV-Ray has implemented metaballs in what they call blobs:

Is your concept similar to representing a set of (x,y) points with a polynomial of increasing degree? From a straight line, to a parabola, to a spline? Or the Bézier_curve? Or something akeen to Fourier_series where the sum of various sin() and cos() of varying amplitude and frequency represents accurately a complex shape?
