This article describes the urban space-time model , \System to Tianjin , for example , the comprehensive utilization of temporal GIS component technology , space-time database technology , and a variety of development software tools in the Windows operating system environment , to achieve in the field of time geography state GIS and MIS organic integrated application system . Paper is divided into four main parts : First, introduced the background and significance of the system development , technical route of the proposed research , describes the current database and application system development theory , technology status and software and hardware , and system implementation the feasibility analysis . Second , on the basis of the needs analysis , data visual integrated development environment , application solutions ; given system function structure design and space use of the ADO, MapObjects2.2 components embedded in the Microsoft VB 6 model selection , and database design . And Tianjin , for example , elaborated on the value conversion method geographic coordinates on the map , the map display control , query results , three-dimensional display , data management , and map output print . Finally, the system development process encountered some technical problems and solutions ; realization method of network analysis functions and explore . The application of the system to achieve good value paths and cluster information of residents' behavior over time to change the law to provide help for urban spatial and temporal data management , analysis , time geography , urban planning , management decision-making services provides reference services .
