Abstract: To develop software of engineering geological information system by adopting the component-based GIS developing technology in combination with the characteristics of engineering geological information can well make up the deficiency of the current engineering geological management system in geographic information management, enhance the spatial attribute management and analysis and meanwhile, greatly shorten the system development speed.Based on this, the application of MapX5.0 in the urban engineering geological information system was investigated, the system development platform was chosen, the system modules, system functions and system database were designed, and the system functional modules were finally realized, achieving the expected design objective.

Key words: Component-based GIS, Urban engineering geological information system, MapX5.0
