摘要

Abstract

In the era of big data

the popularity of POI data applications is rising. This paper aims to identify urban fringe and hot spots based on POI data by kernel density analysis and density-value-distance analysis. On the basis of kernel density analysis

Densi-Graph is drawn and nodes are selected to draw the urban fringe; and then hotspots are identified using kernel density maps based on urban development.
