GEOSPATIAL to the public display, a standalone touchscreen kiosk in the City Council ofﬁces incorporated a user-friendly Web browser interface for exploring the visuals via locality map with hyperlinks. “Bentley provided user-friendly and intuitive software for this project that fully supported the three-step process to building urban 3D models,” Foley explained. “MicroStation has proven it’s the best tool for the job, as it achieved high levels of realism while maintaining the spatial integrity of the underlying data.” Envisioning the future The AU$80,000 project took two full-time and three part-time GIS professionals three months to complete in time for the public involvement period. The three-step modeling process included data acquisition, data processing, and specialized output. Bentley software supported seamless data transfer between surveyors, photogrammetrists, and CAD professionals. Spatial data captured from disparate sources ﬂowed directly into the common DGN format, enabling post-processing in the CAD environment. Bentley software enabled designers to create photorealistic effects, such as modeling yachts in the marina, recreating unique street art and furniture along the waterfront, emulating sunlight at different times of year, replicating various viewing angles and drive-through scenarios, and animating ﬂowing water. Using an inhouse built Virtual Forest Building application, designers even automated the task of creating time-lapsed growth for virtual trees once the model was completed, they could immediately start generating animation sequences, which saved time and reduced bottlenecks. Final rendering was also spread over several machines running the same animation script to share the workload. The 3D model and draft UDF were exhibited from December 2003 to February 2004. Community feedback made it clear that the citizens of Hobart wanted a visionary plan that would set guidelines for design excellence. In May 2004, the Tasmanian government released the ﬁnal Hobart Waterfront UDF, providing the fundamental concepts and principles to guide development. In April 2005, the Sullivans Cove Waterfront Authority assumed responsibility for protecting, enhancing, and developing the cove and surrounding areas. Implementation of the UDF has led to cost savings for potential developers, who can proceed with conﬁdence knowing that UDFcompliant proposals will have a strong chance of gaining v Planners used the model to evaluate various concepts for the 15 potential development sites approval. The approval process takes less time, since the building envelopes for each site have already been deﬁned. For example, a multistory parking garage proposed for one of the earmarked sites proceeded through the planning approval process without controversy, because traditional points of contention such as building height had already been addressed. The photorealistic model continues to serve as a reminder of the people’s vision for the future of Hobart v Hydro Tasmania was tasked with building a photorealistic 3D model to Waterfront.
