자오선 길이의 계산에 관한 연구
A Study on a Computation of the Meridian Length
초록
In geodesy, a calculation of the meridian length is a basic thing. Its principle is very simple, but no exact closed formula exists and its expression has rather long terms. In Korea, the formula has been seemingly adapted from those of Japan which also use the Bessel ellipsoid as a reference. However, a formula from a noticeable reference of Japan is found to have wrong coefficient values. In this study, a formula for the meridian length with correct coefficient values is suggested and the results on different computing bases are also shown. This formula has terms simpler than the one in the Korean Surveying Act (Law) which has the same coefficients in that Japanese reference.
