Why A 3D Model

• No formal business case
• No established funding
• No specific objectives
• it just seemed like the right thing to do.

3D Model History

• Where we are today

20
3D Goes Mainstream
21
Ubiquitous 3D?

• About 5 years ago things began to change
• We had to think about the role of 3D in the City
• Our Conclusion

22
3D Is Easy

• 2D Is Hard

23
Lost In Translation
24
What Is The Role Of The 3D Model?

• Analysis
• Visualization
• Communication
• GIS
• It is all of the above plus lots moreso
• Can one model meet all these needs?

25

• ?

26
3D Can Have GIS Data

• But
• 3D without linked data is still data

27
GIS Data - Abstract
28
3D Model Data Not So Abstract
29
Issues
30
Issues - Exposure

• How useful is a 3d model if only a handful of
  staff have the training or hardware to work with
  it?

31
Issues - Resources

• Work usually as time permits
• Limited budget
• Some revenue through licencing

32
Issues Can One Size Fit All?

• Visualization vs Analysis

33
Issues The Lure Of Pretty Pictures
34
Issues Data Distribution

• Free Cost Recovery Subsidized?
• The Public
• Academic Community
• Development Community

35
Issues - Maintenance

• Keeping it current

36
Issues Emerging Standards?

• City GML

37
Issues Perception - Consistency

• No two people will model a building the same way
• Ask two people to represent a street network, and
  it will be similar
• Exactly what is a building footprint?

38
Issues Level Of Detail
39
Issues How Much Context

• No longer are you just concerned with the area
  you administer.
• All you see is important

40
Issues Multiple Versions

• AutoCAD geo-referenced
• AutoCAD 0,0,0
• Max
• SketchUp (bits and pieces)

41
Issues 3d Silos

• SketchUP is free!
• AutoCAD now does 3D quite well
• How about that Google Earth?
• Hey Microsoft is giving away trueSpace

42
Issues GIS 3D

• How Does one model for GIS?
• Air-space
• Multi-use
• etc

43
State Of The Model

56
How We Currently Use The Model

• Massing
• Views
• Shadowing
• Character
• Light
• Movement

57
Our Primary Construction Process

• New orthophotos flown
• Drawing prepared noting new buildings
• Photogrammetric rooftop collection
• DWG file with reference building framework
• Puzzle solving with SketchUp
• Place in real work position within AutoCAD Map 3D
• Move entire model to 0,0,0
• Import into 3DS MAX

58
Trends
59
Trends

• 3d specialist joined by 3d generalists
• Boundaries between 3D analysis, visualization and
  geo-spatial analysis are blurring
• Younger staff joining the City bring existing 3d
  skills
• 3d use expanding beyond Planning functions
