Create prototype for displaying 3D geospatial data

[brylie]

Without "reinventing the wheel", make a basic prototype showing how to render 3D geospatial data (such as urban buildings). Use one or more existing resources, including any of the following:

• iTowns
  • WFS to 3D objects
• 3D City Database
• Simple 3D buildings

Due to the complexity of working with 2.5D or 3D data, we will defer this task to a later point where it is immediately beneficial.
