Application of Improved Gauss Projection in Urban Surveying

ZHAO Xin;  
Due to the length deformation value of the commonly used projection scheme can't satisfy the requirement of the Urban Surveying Standard. We analyzed and discussed how to choose length deformation parameters of Gauss-Kruger Projection Race in this paper. We improved the projection method, and proposed two types of the superior schemes to satisfy the precision target. Firstly, on the premise of meet the length deformation precision index, the purpose is computing simply. Secondly, the purpose is reducing the absolute value of the projection length deformation, and obtains the corresponding parameter values.
