The regional component of the gravity field in Tasmania has been obtained by approximating a smoothed subset of the observed data by a terminated Fourier series. The trigonometric functions were orthogonalized with respect to the irregularly spaced data by the Gram-Schmidt method. A coefficient set was obtained in terms of the original trigonometric functions to enable the regional component of the field to be calculated at any arbitrary position.
