2.4.2. Extraction of Urban Morphological Parameters

The subject area's similarities and differences can be quantitatively investigated by the division of calculating units. The neighborhoods were divided into 20 units according to road boundaries, spatial structure divisions and the size of typical urban neighborhoods by a 200 × 200 m grid (Figure 5). The Beijing Institute of Surveying and Mapping was used to obtain the 3D environmental data of the neighborhoods, while the sociological data were

obtained from the field survey. The selected morphological parameters were calculated separately in ArcGIS 10.5.
