Tang Zhong-an · Engineering of Surveying and Mapping · 2011
Based on Hunan provincial current geodetic control data and the theory of Information diffusion estimation,the paper analyses the modeling public point datum quality between the coordinate systems of China Geodetic Coordinate System 2000,Beijing Geodetic Coordinate System(1954) and Xi'an Geodetic Coordinate System(1980),and provides a base for later model optimizing and its quality assurance.Based on these facts,the paper also researches various geodetic coordinate system conversion algorithm;provides the results by the living example calculation and the comparison and analysis of the models precision;brings forward a suitable solution to China Geodetic Coordinate System 2000 for Hunan province,and develops the corresponding coordinate system conversion software which is used widely in the whole province.
