High-Speed Railway Fundamental Information Database System and its GIS Subsystem

High-speed Railway Fundamental Information Database System (HSRDB) is an important science and technology project of railway ministry in 2006 of China. The aim of researching and designing about HSRDB is to build High-speed railway database system that perfecting and extending along with the development of High-speed railway, HSRDB has features of comprehensive content, integrated classification, legible history and high timeliness and efficiency. This paper introduces main functions of HSRDB and key problems in its achievement. It also introduces the functions of GIS subsystem and its key technologies. Based on advanced information technology of decision support, data warehouse and data mining, HSRDB fulfills the function of query and intelligence search of text, graph and multimedia data and it provides the function of technology statistics and contrast analysis in correlative domain. On the basis of MapXtreme, the GIS subsystem can provide high-speed railway sketch map of various countries such as China, Japan, Italy etc. It also provides layer exhibition query of line, station, motor base, bridge and tunnel etc, and it can also query correlative literature, design and fundamental data. The application of the system indicates that the proposed solution is a flexible and efficient tool. The system caters to the demand of ministry leaders, railway transport enterprise, scientific research and design institution and railway construction enterprise, it can help High-speed railway constructing and developing of China.
