2000国家大地坐标系是我国建立使用的第一个地心坐标系,根据原国家测绘地理信息局要求,山东省2018年组织开展了全省国土资源数据转换工作,市一级国土资源数据转换需要工作繁杂、数据量大;我院率先开展试点地级市国土资源数据转换工作,本文详细介绍了市级数据转换的流程和经验;为全省其他地区转换工作以及后期国土资源工作中数据转换提供参考。

China Geodetic Coordinate System is the first geocentric coordinate system established and used in China.According to the requirements of the former National Bureau of Surveying and Mapping Geographic Information,Shandong Province organizes comprehensive data conversion.Municipal level land and resources data conversion needs complicated work and large amount of data.As a pilot area at the municipal level,Pilot City takes the lead in the transformation work.This paper introduces the process and experience of city-level data conversion in detail.It provides reference for data conversion in other areas of the province.
