Design of Geographic Environment Database for Railway Route Selection in Wind-sand Areas Based on GIS
Research purposes:Geographic environment data is the foundation for railway route selection design.To solve the problems of data storage management,spatial analysis and design application for railway route selection in wind-sand areas,a geographic environment spatial database system for railway line design in wind-sand areas based on GIS was established by utilizing the advantages of GIS in spatial data management and application system construction.The application level and work efficiency of multi-source heterogeneous data in railway design was improved through the system.Research conclusions:(1)According to the characteristics of the influencing factors of route design,the design ideas and key technologies of spatial database for the geographical environment of route selection in wind-sand areas were studied in terms of data organization and overall structural design.(2)With the help of VS compilation environment and AE technology,a database system was developed using C# language that integrated spatial data and fusion applications of railway geographical environment.(3)The storage,unified management,and spatial analysis of multi-source heterogeneous spatial data and attribute data in the design of wind-sand areas were realized,which enhanced the application ability of data.(4)The research results can provide effective technical support for railway route selection of disaster reduction.
