This analysis is part of the analysis on the impact of city walls on the urban growth in Zhengding. Points-of-interest (POI) show the distribution of different functions in the city. This analysis selected the type of POI most related to residents’ everyday life, that is, retail stores and restaurants, and visualised their distribution in the city.
The POI data was acquired from amap.com (高德地图), the most popular web map service provider in China, with the tool EasyPOI developed by Ditubang. Then the data was imported into QGIS and visualised as a heatmap. At last, the visualisation of POI distribution was overlapped with the results of Space Syntax analysis (see the analysis→).
The result is shown in the following figure:
