Abstract
Abstract
In a recent paper, H. A. Winkler developed a suitable method for determining longdistance terrain corrections in gravity by interpolation. Such a technique implies that it is necessary to take into account the changes of the correction g not only with the location (X, Y) but also with the elevation Z of a station. Study of the function g(Z) shows that its curve, with amply sufficient accuracy, may be represented as a parabola. Moreover, the parabolas corresponding to different stations are all equal. From these properties a method has been derived which saves computing time and yields long‐distance terrain corrections with convenient accuracy.
