Abstract

Urban surface morphology characteristics mainly expressed by the shape of artificial building entities. Based on DLG data and field surveys, urban building entity model and point model of the vector-based surface model are constructed. In addition, from the view of exploratory spatial data analysis (ESDA) and spatial statistical analysis, a set of analysis and evaluation methods of the characteristics of urban layout are designed. As test areas, urban spatial distribution and pattern of the old city of Nanjing in China are analyzed. Experiment also showed that the surface model of the city based on the vector construction entities can better reflect the main patterns of urban surface characteristics and three-dimensional trend information on the characteristics of obvious benefit to deep analysis.
