There are several geodetic coordinates systems in China,such as Beijing'54 geodetic coordinates system,Xian'80 geodetic coordinates system,WGS-84,etc.These coordinates systems coexist together,and each has its characteristic and applications.A practical coordinates transformation method for map updating is investigated and the transformation results are analyzed and compared in this paper.The transformation results show that this practical method is bale to meet the requirements of land surveying.
