互联网地图在公路测量中的应用

Application of Internet map in Highway Surveying

介绍了互联网地图在公路测量中的找点、选线、测图、绘图环节中的应用方法,阐述了传统纸质地图和互联网地图在公路测量中各环节的作业流程、技术方法、投入的人员等各自特点,同时对二者的优缺点进行了分析比较,得出了互联网地图较纸质地图在成图、作业效率、质量保障等方面的明显优势,同时还探讨了互联网地图作业中的涉密问题和作业员在测量中应遵循的保密法则。互联网地图内容丰富形象,具有可与GPS定位联动的实时性。互联网地图的应用改变了传统作业模式,提高了公路测量的工作效率和作业质量,降低了项目成本,对公路测量工作具有重要的现实意义。

The application of internet map in highway survey including point detection,line selection,mapping and drawing is introduced.Moreover,the operation process,technical method and personnel in the various aspects of highway survey in both the traditional paper map and the internet map is expounded,the advantages and disadvantages of which are analyzed and compared.The internet map has obvious advantages comparing with the paper map in mapping,operation efficiency and quality assurance.The involve-secret problem in internet map homework,which reminds the operator that should follow the confidentiality rules in the measurement is pointed out in this study.The richness and visualization of internet map content and real-time linkage with GPS positioning are incomparable to paper maps,which application has changed the traditional working model,improved the work efficiency and quality of highway survey,reduced the project cost.This study has given a practical significance for highway surveying.
