Abstract

In the information era, the distribution pattern of point of interest (POI) data points in urban space is of great reference significance in urban infrastructure planning and urban spatial analysis, providing a basis for studying the identification of urban functional areas. With the downtown area of Changchun as the research object, the POI data was quantified according to the classification of the urban functional areas, identifying the urban functional areas in the downtown area of Changchun. The experimental results were compared with the current urban land use maps in Changchun to demonstrate the feasibility of the experimental method. Compared with traditional methods, this method features fast analysis speed and digital attributes, which is of certain value for urban geospatial planning.
