摘要
Abstract
The parameter ellipsoid and the transformation parameter in local urban independent coordinate sys⁃tem are always kept secret. In this paper, a method using pseudo seven parameter and four parameter to acquire real⁃time local cities independent coordinates was introduced with GPS⁃RTK surveying, and the model was briefly dis⁃cussed. Then the accuracy of the conversion using this method was analyzed through the example, and some valu⁃able conclusions of engineering were obtained.关键词
