Abstract: There is no doubt that the elevation benchmarking is an important part of engineering application. Obtaining a stable and reliable elevation benchmark is an indispensable part of engineering construction. GPS positioning technology is a reliable method. In order to solve the problem of how to transform the height of the GPS into the normal high, this paper proposes a segmented elevation fitting method combined with elevation fitting models. Combined with a mine project data and the overall elevation transmission for comparative analysis, some useful conclusions are drawn.
