Application and Research of GIS in Tianshan Highway Geo-hazard Appraisal and Decision Sustain

Analyzing the on the theory of geological disease about Tianshan road in detail, collected the datum of basic geography and geology along the lines of road in the past, and also combined the technology of database and remote sensing images manipulation, according synthesizing, coordinating, choosing, concluding and changing by the rules of database. It offered the favorable resolving for region stability assessment, the highway alignment route selection and 3D Visualization analysis, integrating GIS spatial analyzing technology to the Tianshan highway geo-disease appraisal and decision-making. The system developed a set of GIS manipulation flat of collecting foundations data gathering, the memory, the management, the searches, the graphic editor, the space model analysis and so on. Adopting integration exploiting technology of ArcEngine and Visual C#. Building multiformity information database the Geography database and the geological hazard database based the platform of ArcGIS. Managing space data and attribute data subsequently using ArcSDE. It is reliable scheme to engineering geo-disease appraisal and decision-making.
