Research on key technologies of railway geographical information platform

摘要

As the most fundamental supporting platform in railway infromationization, the railway geographic information platform can display the railway geographic information intuitively. Since MIS is commonly used in the railway system, in this paper, we propose the system framework to meet business needs for spatial data. Also, we develop the following techniques: data classification and integration, data acquisition and process, data organization modelling, and data sharing. These techniques enable the platform to display the railway network information correctly and completely, realize the data and service sharing to the maximum extent, and finally enhance the railway operation management level.
