Research on Coordinate Transformation Method Introducing Datum Rotation Center
摘要
Abstract
In a regional plane coordinate system,due to strong correlations between coordinate vectors in the coordinate systems,the matrix of normal equations creates severe ill-conditioning in the coordinate transformation,and leads to unreliable transformation parameters between the coordinate systems.The ill-conditioning of the transformation coefficient matrix is solved by introducing datum rotation center in the plane coordinate transformation model,and reliable coordinate transformation parameters are obtained.This method is validated with practical data.关键词
