| Description | Journal: Journal of Physics: Conference Series Obtaining the elevation of ground points is a basic work for studying the shape of the earth and engineering construction, and can be used in civil construction, water conservancy engineering, mineral engineering, etc. Aiming at the problem of low leveling accuracy in complex mountainous area, this paper proposes a "remove-restore" leveling method based on EGM2008 model and quadratic polynomial fitting. Taking an a complex mountainous area as an example, the results show that the external accuracy of this method can reach 4.3 cm. |
