Based Mapobjects Transportation Infrastructure And Information Management Analysis And Research

With the development of social economy and need of people's life, the traffic infrastructure is improved constantly . Fundamental geographic information system is more broader aplied in the field of transportation form the single field of road and railway or single railway construction and measurement to every field and aspect of traffic . To set up a convenience, swift the traffic basic information system,it could not only imaginal and accurately reflect traffic basic information,but it also could reflect endemic function of a certain in the field of traffic,which becomes an aspect of traffic basic information nowdays. This article combines with need of traffic infrastructure construction at present ,and based on component development technology of GIS,it deeply studies and practice for project of program management. Eventually,this article combines with precise measurement technology of Ballastless track,which it provides high precision of original collecting data for traffic GIS system. This paper mainly studies as followings:(1) Combined with general feature of traffic information system,it realizes the basic functions of traffic basic information system,and Studies on traffic basic information system which is related collection of precise measurement and establishment of database about Ballastlesstrack .(2) with regarded to what it mentions the enough CAD relief map of the traffic ,adopting more simpler,convenienter method of Arcgis soft,I adopt point,line,face directly or stratified directly change shp form,but general method adopts arctoolbox change coverage form first,and then change the shp form。(3) Regard Visual Basic 6.0 as the visual developing platform, the ComGIS-MapObjects 2.3 with comparatively complete function as the figure display tool, not only suitable for the habit that most users use Windows but also meet figure information of users' needs, can also reveal the highway information of different grades separately。(4) According to principles and methods of GIS Engineering and characteristics of road management system, this paper designs interface, analysis and output, and thematic map, etc。(5) Construction of the system use visual developing tools, and make the best of the functions of map operation, data editing offered by mapobjects, it greatly raised the efficiency of the system development。The system is universal, transplantable, security and extensible, and it has a nice interface which can be operated simply。(6) The precise measurement technology of Ballastless track has carried out on preliminary study and practice,which it can provide real-time rectification for Ballastless track in construction of Ballastless track,also it can provdes data collection and guiding of construction for Ballastless track。...
