The project aims at transferring a community redevelopment plan as done by the student in 2010, including its general layout, transportation system, dwelling types, and spatial organization, into a 3D simulation model within Esri CityEngine. The project has a two-fold goal: 1) to explore 3D GIS application in urban planning and community design, and 2) to explore Esri CityEngine as a powerful tool of building 3D communities.

5. Goals and Objectives
The project has a two-fold goal: 1)
to explore 3D GIS application in
urban planning and community design,
and 2) to explore Esri CityEngine as
a powerful tool of building 3D
communities.
To achieve this, the stage-by-stage
objectives aim at converting the 2010
redevelopment plan into a realistic
3D model with Esri CityEngine.
