| Abstract: | In this paper, how to evaluate the relative error of plane control network is theoretically analyzed, the transformation relationship of the covariance matrix in different datum and the problem to evaluate the relative error accuracy using the transformed covariance matrix are also discussed. With the help of the developed mathematical model, the plane control network adjustment with the function of computing relative error has been programmed with Matlab. The practical project is studied with actual data. |
