| Abstract: | As China Geodetic Coordinate System 2000(CGCS2000) starts being used,the coordinate of surveying and mapping products need to be transformed and the method of coordinate transformation with high accuracy also need to be studied.Large residuals still remain after the transition by use of Bursa model from the astro-geodetic network of our country to high-precision geocentric coordinate system.In order to improve transformation accuracy,grid coordinate transformation is used to fit residuals further,in which c... |
| Keywords: | Bursa model covariance function prediction Reilly function multi-quadric function prediction grid coordinate transformation |
