1954年北京坐标系和1980西安坐标系精度分析及其适用性研究
ANALYSIS OF ACCURACY AND APPLICABILITY OF TRANSFORMATION BETWEEN 1954 BEIJING COORDINATE SYSTEM AND 1980 XI'AN COORDINATE SYSTEM
摘要
Abstract
Employing the coincidence point between reference-ellipsoid-centric coordinate system and the CGCS2000 which are proportional distributed, of hight accuracy and well-currency, using the Bursa model to transform the coordinate and from the transformation residuals, the coordinate' s plane accuracy of the 1954 Beijing Coordinate system and the 1980 Xi' an coordinate system are analyzed, objectively evaluate the applicability and put forward some reasional suggestion about the continuance or suspense of asing the 1954 Beijing coordinate system and the 1980 Xi' an coordinate system.关键词
