Geodetic method
WebAug 3, 2016 · Values of astro-geodetic geoid undulations (of stations) have been found close to that computed from field levelling. Further, the values have been compared with those obtained from global geoid models such as EIGEN6C3stat and EGM2008, and the astro-geodetic method was found to provide better accuracy than the global geoid models. WebThe Plane surveying method is suitable for surveying up to 250 km 2 area. The plane surveying methods are used in the construction of dams, bridges & road work. Geodetic Surveying. The earth’s surface not considered as plane and curvature of the planet also taken into account for measurement is called Geodetic Surveying.
