Research and application of key technologies of digital engineering geological mapping system for land transporation engineering
The method of indoor and outdoor collaboration has been introduced into the engineering geological mapping.Based on the three-step standard business process of"indoor virtual adjustment-outdoor adjustment and verification-indoor data collation",this paper develops web,desktop,mobile and server application systems applicable to the above methods based on GIS platform,and studies multi-data fusion,regional geological map section,digital occurrence measurement,digital acquisition template configuration as well as multi-terminal data collaboration,which helps innovate the geological mapping operation mode,and improve the quality of engineering geological mapping results.Through this study,the digital drawing process standard,its technical requirements standard,as well as its mapping achievements are summarized and are well verified in the Yichang-Fuling railway.It is found that the indoor and outdoor col-laboration mode can properly reduce the outdoor workload and improve the efficiency and quality of engineering geological mapping.The indoor virtual geological mapping can make reasonable use of rich data and expand the macro-perspective of geological mapping as well as the continuity of achievements.The independently configured geological mapping template can ensure the consistency of indoor and outdoor geological mapping experience as well as data inheritance and reduce the maintenance difficulty of software system.
