摘要
GPS可实现高精度定位,已广泛应用于各种大型工程,但短边GPS控制网在小型工程中的应用少有人关注。本文以郑州市某高校为测区,以三等导线网为基准对比分析四种不同网形精度,结果表明:c网形精度最高,达到《工程测量规范》(GB 50026-2007)三等精度;第三种方案精度最高;四种网形均适用于地形测量、地籍测量、土地测量、建筑施工测量、水利施工测量、土地整理及土地确权。
GPS can achieve high-precision positioning,has been widely used in various large-scale projects,but the application of short-side GPS control network in small-scale projects has received little attention.In this paper,a university in Zhengzhou was taken as a survey area,and the three-class traverse network was taken as a benchmark to compare and analyze the accuracy of four different network forms.The results show that the C network form has the highest accuracy,reaching the third-class accuracy in the code for Engineering Survey(GB 50026—2007),and the third scheme has the highest accuracy.The four types of network are suitable for topographic survey,cadastral sur⁃vey,land survey,construction survey,water conservancy survey,land arrangement and land right determination.
