Study on the Coordinate Transformation of the Built up Area in Fuxin City
CUI Li-ping;WANG Chong-chang;College of Surveying,Mapping and Geographical Science,Liaoning Technical University;
The plane coordinate conversion between local coordinate system and state coordinate system,because of the difference of the origin,cause the simplified model with four parameters coordinate conversion matrix may be ill conditioned,thus the solution parameters are not reliable. Based on the four parameter model,the coordinates of the center point and the coordinate transformation matrix have the characteristics of correlation. Based on the above principles,the program uses the Fuxin city to verify the coordinate data,the method is simple,feasible and reliable,and the conversion coordinate precision can meet the requirements of large scale measurement accuracy of Tutu root control measurement.
