Design and Application of Software for Selecting the Best Compensation Elevation Surface Based on C#Language
It is stipulated that the precondition of establishing or selecting the planimetric coordinate system is that the length deforma-tion caused by the projection in the survey area is not more than 25mm/km.The national coordinate system adopted by the highway engineering construction control network in a survey area cannot meet this requirement.In order to reduce the influence caused by the deformation of Gaussian projection length,this study chooses the method of expanding ellipsoid and barycentric coordinate invariance to establish the engineering compensation coordinate system,and designs the software for selecting the best compensation surface of the compensation coordinate system based on C#language.The research results show that the calculation method is rigorous and reliable,the software calculation results are fast and accurate,and the automatic processing of compensation coordinate calculation can be real-ized,which can meet the specification requirements and can be directly applied to engineering production.
