摘要
以云浮市中心城区范围为例,对GPS-D级控制网的布设、观测、基线解算以及网平差进行了阐述和分析,采用了高程拟合方法获取高程成果,通过数据统计分析,得出了项目成果符合标准规范要求,精度良好,质量可靠,满足测绘地理信息管理、城市工程建设、规划设计等需求,可为类似工程提供参考。
Taking Yunfu City downtown area as an example,the GPS-D control network layout,observation,baseline solution and network level difference were elaborated and analyzed,using the elevation fitting method to obtain elevation results.Through the statistical analysis of the data,it was concluded that the project results meet the requirements of standards and specifications,with good accuracy and reliable quality,meeting the needs of surveying and mapping geographic information management,urban engineering construction,planning and design,and can provide reference for similar projects.
