A binomial expansion is a powerful tool in geodetic research. It is often used in terrain correction and isostatic compensation. The behaviour, convergence and truncation of the binomial expansion are investigated. The relation of the topographic height H (or the compensation depth), spherical harmonic degree n and the binomial series term m is discussed using theoretical and numerical results. According to the relation. a truncation number M is determined for obtaining an accuracy of 1%, i.e, it can be found how many terms (or power numbers of the topography) should be used in practical calculations.
