| Abstract: | Coordinate transformation is a professional problem which is difficult to solve. Based on the coordinate transformation principle of both different reference ellipsoids and similar reference ellipsoids,a computation software for coordinate transformation among different coordinate systems and between two projection zones was developed. And the key techniques of programming the software as well as the functions of it were introduced. Some structure bodies and different classes were defined by the VC++ language,realizing the computation of 4 parameters as well as 7 parameters under the condition of different reference ellipsoids and the computation program for co-ordinate transformation and strip exchange of the co-ordinates among different coordinate systems. Finally,the applicability and accuracy of the software were verified by a set of coordinate data in a mining practice. Resutt indicate that the software is reliable and simple in operation, which meet the requirement of accuracy. 1fig.,2tabs.,8refs. |
