Most GIS-related planning practices and education are currently limited to two-dimensional mapping and analysis although 3D GIS is a powerful tool to study the complex urban environment in its full spatial extent. This paper reviews current GIS and 3D visualization uses and development in planning practice and education. Current literature provides little information in 3D GIS education. This paper offers suggestions for 3D GIS course setting and educational methods aiming to set up a framework to supplement current two-dimensional GIS education in planning using 3D modelling programs.
