Determination of optimal compensation projecting plane for restrictions of the length projection deformation

Li Zufeng(Engineering of Survying and Mapping Team;Northwest Hydro Consulting Engineers;CHECC,Lanzhou 730050,China)  
Based on the principle of Gauss projection and standards on the smallest total projection deformation of Tunnel axis length,this paper introduces the calculation of optimal compensation projecting plane to have the projection deformation of GPS measurement length smaller.In order to make the GPS length highly consistent with the ground practically measured length,the paper also gives quadratic optimization method of optimal compensation projecting plane,which is based on scale residual of practically measured length.
