浅谈城市地下管线测量

Modern pipeline measurement

随着测绘科学技术的发展,新仪器、新设备、新技术、新方法不断涌现,作为城市基础建设的地线管线探测行业也进行了不断的变革,由最初的简单调绘、平板成图到今天的数字化、网络化经历了十几年的风雨历程,其正随着城市化的发展在逐步走向成熟。本文在实践的基础上对地下管线探测中的测绘知识进行了探讨,对其进行了精度分析并分析了其误差来源;对其探测成果的内业处理程序进行了分析,能使人对管线探测行业有初步的了解。

With the development of the mapping of scientific and technological ,new equipment,new device,new technology and new methods are constantly emerging.As the city ground infrastructure,underground pipeline detection has also increasingly been innovated.From the initial draw for a simple,flat map to today's digital network,after having experienced more than 10 years of ups and downs and the development of the city gradually ,it is becoming more mature.Based on the practice,this paper studys the knowledge of the detection of underground pipeline mapping and analyses its accuracy.Meanwhile it analyses its error sources.For analysing the inner processing of the outcome of its detect,people can have a preliminary knowlege of this industry.
