摘要
目前,全国各地都在进行第二次土地调查,我单位完成了浙江省某城区1∶500测图项目一级GPS控制网的布设任务。本文针对在复杂城区布设一级GPS控制网的特殊情况提出了新的设计方法和数据处理方案,该网的精度统计数据表明:新布设的GPS网其精度满足城市发展规划和地籍测量的要求。
Now the second land survey has been performing by the survey departments through out the country. Our department had finished the mission of establishing and surveying the first class GPS control grid for the surveying and mapping project at a scale 1 ： 500 around a complex city in Zhejiang Province. The,paper summarized new methods of designing the first calss GPS grid around complex city and solutions for data processing. The grid＇s accuracy statistics show that： the new layout of the GPS grid can meet the urban development plan of its accuracy and related cadastral measurement.
