Compared with the traditional map information platform, the urban big data information map has the charactics of positioning, visualization and real-time monitoring. At the same time,, the urban information map can achieve the comprehensive information expression and linkage analysis from the surface to the deep of the urban various system and unit. On this foundation, this paper constructs the three-dimensional building accuracy urban spatial database including the building monomer-land block-road red line-block unit-terrain topography. And, it sums up the complex multi-source database including the urban greening system, urban municipal system, urban microclimate system, urban industrial system, urban vehicle system and urban imagery system. Then, it forms the basic model of urban spatial large data map based on unified spatial coordinate system through ArcG IS platform, combining the spatial form database and composite database. Finally, it can obtain multi-source data fusion characteristics of integrated information, and optimize the planning and design of scientific decision-making according to the urban planning, urban design and management needs.
