Landscape models have been widely used to study urban landscape patterns and urban dynamics. However, studies have been limited to surficial directions to examine urban development patterns, and a vertical view of the urban landscape is often overlooked due to lack of data or a systematic quantitative model to depict the 3D dynamics. By incorporating a DTM model from Lidar data of the Washington DC metropolitan area, this paper develops a 3D Landscape Model to evaluate the urban growth of the region in both 2D and 3D perspectives. Socioeconomic variables are included in the model to interpret the surficial and vertical urban dynamics in the DC metropolitan area.
