奥维互动地图在赫章高位隐蔽地质灾害排查中的应用

Application of Ovi Interactive Map in High and Concealment Geological Disaster Survey of Hezhang County

常规的“图纸+GPS”野外调查方法已无法满足现阶段地质灾害排查工作的需要,为寻求高效、精准、高质量的地质灾害数据采集技术,作者结合赫章县高位隐蔽性地质灾害隐患专业排查项目,以奥维互动地图的应用为研究对象,通过分析奥维互动地图的技术优势,并针对地质灾害排查工作中存在的导航找点难、信息采集过程繁琐、调查底图制作费时等系列问题,探索了奥维互动地图在赫章县高位隐蔽地质灾害排查中的应用,包括外部矢量数据源处理与导入、地质灾害解译、路线导航、点位查找、信息采集、位置共享以及内业成果处理等;提出了较为系统高效的地质灾害野外调查技术与方法。研究成果可为今后地质灾害野外调查环节提供技术参考。

The conventional“drawing+GPS”field survey method can no longer meet the needs of geological hazard inspection at this stage.In order to seek efficient,accurate and high-quality data acquisition technology for geological hazards,The author combines with the professional inspection project of hidden geological hazards in Hezhang County.Taking Ovi Interactive Map as the research object.By analyzing the technical advantages of Ovitalmap,Aiming at the problems in geological hazard inspection,such as difficult navigation,cumbersome information acquisition process and time-consuming production of inspection base map,etc.This paper explores the application of Ovi Interactive Map in high and concealment geological disaster survey of hezhang county.Including partial vector data source processing and importing,geological hazard resolution,route navigation,point location search,information collection,location sharing and internal results processing;A systematic and efficient field survey technique and method for geological hazards is proposed.The research results can provide technical reference for the field investigation of geological hazards in the future.
