Spatial Analysis Method of Urban Design Based on Big Data

With the development of information, digitization and network, the connotation and form of urban space are undergoing new changes. The limitations of traditional urban design methods to integrate and plan urban space are becoming more and more obvious. Based on big data and new technology, the analysis methods of vector space, 3D GIS and data flow simulation can effectively break through the limitation of space design on a series ofstatic and relative plane design frameworks and platforms, such as 2D layout, 3D elevation design and meeting the targets; the problem of urban design is to stop on the design division and superposition of two-dimensional layers, and constantly divide and cut, without fusion and dynamic systematic distribution.
