Abstract

In highway surveying and mapping, scientific selection of elevation compensation surface and arbitrary belt Gaussian projection coordinate system is very important, the results will directly affect the survey and mapping effect, and then affect the quality of the whole highway surveying and mapping project. Taking S project as an example, this paper studies how to establish reasonable elevation compensation surface and Gaussian projection coordinate system of arbitrary belt in highway engineering survey and mapping. Combined with the characteristics of highway survey and mapping projects and the requirements of projection deformation specifications, the selection of elevation compensation surface and Gaussian projection deformation are analyzed. Through reasonable selection of projection belt and projection surface, combined with specific formulas, The projection parameters and the selection of offset surface are calculated. Finally, the linear phase junction and projection deformation in elevation offset are discussed, in order to provide valuable reference for related research.
