Abstract：In order to utilize the prior information of similarity coordinate transformation parameter fully and availably and improve the accuracy of coordinate transformation at the same time, we put forward a new method using adaptively sequential coordinate transformation with classified adaptive factor to calculate the coordinate transformation parameters in different region. According to the parameters of different type and different dimension, the different adaptive factors are constructed. An example of practical data processing shows that the adaptively sequential coordinate transformation with classified adaptive factor is superior to the sequential coordinate transformation in threedimensional coordinate transformation.
