| Abstract: | According to the principle of the spherical geometry, this paper approaches the methods of the earth curvature in surveying. It gives accurate formulae of the EDM trigonometric leveling and the ordinary trigonometric leveling. Also, it gives accurate calculation formulae of the earth curvature correction of the EDM trigonometric leveling, the ordinary trigonometric leveling and leveling. The strict mathematic relations among slope distance, horizontal distance, geodetic line length on the instrument level surface and geodetic line length on the geodetic level surface (or on the surface of reference ellipsoid) has been given. |
| Keywords: | earth curvature accurate correction EDM trigonometric leveling ordinary trigonometric leveling slope distance horizontal distance geodetic line |
