Abstract: According to the characteristic of spatial and temporal geographical data on urban, such as multi professional category,multi data format, data dispersion and so on, the management schemes of the grid format data, the data of the graph form, the data of the element type, the similar GIS data and the ArcGIS data of 5 kinds of geography space time data are put forward.Using map enhancement technology based on rich client, dynamic representation of temporal and spatial data based on time frame, spatial data and platform function self expanding custom technology,the overall design of the data management and application platform of the urban geography space time and space is carried out. The trinity system of resource creation and management system,information integration and sharing systems,data interactive application system is developed. The high efficiency of data management and application in urban geography time and space has been realized. The technology method proposed in this paper has been verified in the project construction of information integration management and application sharing platform for planning traffic survey in Changsha city, which provides the technical experience for the integration management and sharing application of the urban geography space time big data.

Key words: geographical space time, big data, management and application platform, rich client, time frame, self expanding custom
