摘要
针对甘肃基础测绘成果数据类型多样、格式多样、存储方式多样、横跨六个三度带以及甘肃西部地区控制稀少和转换图幅多的特点,对数据成果和各种类型转换方法进行对比分析,形成了甘肃基础测绘成果转换的技术路线和实现方法,并成功地实现了甘肃省基础测绘成果的整体转换,该技术路线和方法对国家测绘地理信息局组织开展的全国CGCS2000基础测绘成果转换具有一定的借鉴意义。
Due to CGCS2000 is a new generation of national geodetic coordinate system,it is significance to research of the methods of transformation Gansu basic surveying and mapping products into CGCS2000. The paper’s results successful come over many problems,combining with Gansu basic surveying and mapping products features,such as data typesanddata format varied,six three degree zones crossed,and control points scarcely in western of China. By analysis of different methods and transformation results,the technical route and conversional implementation methods has been narrated and we has completed the overall conversion of basic surveying and mapping productsof Gansu province. So this could be utilized in the national CGCS2000 basic mapping production transformation,which organized by National Bureau of Surveying and mapping geographic information.
