| Abstract: | Based on the analysis of application modes of geographic information system (GIS), the basic idea and characteristics of three-tiered architecture were presented, and an integrated application model for railway GIS was proposed based on three-tiered architecture. Furthermore, the whole planning of railway GIS based on three-tiered architecture technologies was disscussed. An application system of railway GIS was developed using MapObjects and (C )Builder, and this system characterizes high efficiency, stability and expansibility. The application result shows that it is feasible to apply three-tiered distributed technique to railway GIS. |
