Development And Application Of Railway Land Geograhpy Information Systom

Railway land management is an important foundation to guarantee the safety and smooth of railway transportation. This paper mainly does research on the related business of railway land management. Then it analyzes the demand of railway land geography information system(railway land GIS). And lastly it develops railway GIS for railway engineering department., in order to strengthen the railway land management and improve the level of information of railway management.This paper first analyzes the research status of the railway land geographic information system toknowsthe application situation of domestic and foreign GIS technology in land information management. And then based on the in-depth study of geographic information technology and 3D visualization technology on GIS, this paper analyzes and summarizes the main demand of railway land GIS for railway engineering department business, such as data management, land surveying, railway emergency management, disaster prevention and mitigation and risk management, equipment maintenance management and railway land and housing management. Based on the abovetheoretical research anduser needsanalysis, the railway land geographic information system frameworkis designed, including software system structuredesign and physical structure design. Andthesystem development platform and development tools is determinedto complete thedesign ofsystemfunction module.Then, this paper based on the related theories of spatial data, conducts an in-deep research data system of railway land geographic information system and analyzesthe railway engineering spatial datacharacteristics and management method. And it determines the data structure and organization according to Arc View spatial data format. Lastly it completes the design of the database system, and has completed the system development.Finally, it introduces the main function of the interface and system.
