Urban Functional Area Identification based on POI Data

Abstract

With the deepening of urbanization, the urbanization process is gradually accelerated, and the urban spatial structure is constantly changing. The identification of urban functional areas is of great significance for optimizing the urban spatial structure and analyzing the behavior characteristics of residents. The emergence of geographic information data such as POI provides a new perspective for the study of urban functional area identification. This paper illustrates the identification of urban functional area based on POI from two perspectives: the data sources commonly used in the field of urban functional area identification and the methods commonly used in the field of urban functional area identification.
