省级国土资源空间数据坐标转换探讨

Discussion on Coordinate Transformation of Provincial Land and Resources Spatial Data

国土资源数据以空间数据为主,支撑着各级国土资源日常管理和监管工作。为推进国土资源空间数据的共建共享与应用,需要全面开展国土资源空间数据2000国家大地坐标系的转换工作。本文以省级国土资源空间数据从1980西安坐标系向2000国家大地坐标系转换为例,对省级国土资源空间数据坐标转换方法进行探讨。

Land and resources data is mainly spatial data,which supports the daily management and supervision of land and resources at all levels.To promote the co-construction-co-sharing and application of land and resources spatial data,it is necessary to carry out the transformation of China Geodetic Coordinate System 2000 of land and resources spatial data.Taking the transformation of provincial land and resources spatial data from Xi'an geodetic coordinate system 1980 to China Geodetic Coordinate System 2000 as an example,the coordinate transformation method of provincial land and resources spatial data was discussed in this paper.
