摘要
针对广州市存量国土规划空间数据坐标转换需求,本文介绍了常见坐标转换模型,研究制定了技术路线、坐标转换流程,探讨了空间数据坐标转换质量控制要点,并以广州市黄埔区2000坐标转换工作为例,介绍了该方法的实际应用。
To deal with the coordinate transformation requirements of stock spatial data of land resources and urban-planning in Guangzhou,this paper introduces common coordinate transformation models,develops the technical route and coordinate transformation procedure,and discusses the key points of quality control in spatial data coordinate transformation.It takes the CGCS 2000 transformation in Huangpu district of Guangzhou as an example to introduce the practical application of this method.
