摘要
CORS技术是近年来出现的一种融合卫星定位技术、计算机网络技术和数字通信技术的测量新技术。以济淄线天然气管道测量项目为例,介绍了利用CORS技术进行管道测量的基本原理,探讨了CORS技术在地下管道测绘中的作业实施方案,围绕管道测量的主要内容和精度要求,从管道中线测量、带状地形图测量、穿跨越测量等环节阐述了测量控制方法。通过对测量结果进行复核后发现,与传统测量技术相比,CORS技术具有工作效率高、精度高等优点,应用价值较高。
CORS is new survey technology that combines satellite positioning technology,computer technology and digital communication technology.Taking Ji-Zi natural gas pipeline survey project as an example,introduced is the basic principle of CORS survey technology,discussed are implementation schemes of the CORS survey technology in underground pipeline survey project and described are survey control methods for center line survey,strip topography survey and cross and overhead cross survey in combination with main content and precision requirements.Compared are survey data obtained by CORS survey technology with those obtained by traditional survey technologies and results show that the CORS survey technology has such advantages as high efficiency and precision and has high application value.
