Remote Sensing Survey Of Geological Disasters And Spatial Information Integration In Zhouqu

In this paper，it use the high-precision remote sensing data， DEM data to build thethree-dimensional scene of Zhouqu. survey the environment， geological disasterconditions of major geological disaster point in the three-dimensional environment，identify the environment surrounding disaster points and in the basin-wide， identifythe distribution characteristics， body size and type of secondary disasters， analysisthe development characteristics the formation mechanism and reason of the geologicaldisasters， provide the foundation data for the establishment of the the Zhouqugeological disaster monitoring and warning system， and provide a scientific basis forthe post-disaster reconstruction and disaster mitigation and prevention planning;While using geographic information system technology， based on atwo-dimensional system Arc GIS and three-dimensional system Skyline. Developed thegeological disaster spatial information integration system using C#language. integratedthe data of basic geographic data， the data of geological disasters， the data ofgeological disaster control engineering ctively， and can link， query， statistics andanalysis in two or three-dimensional GIS platform.Reached target of secondaryrestructuring and upgrading of multi-source information， and provide technical supportfor the multi-objective analysis and management of multi-source information， whichprovides the IT security for the coordination and management of geological disastercontrol.
