Why 3D?
Why 3D?
Traditionally we manage our cities like this…
Why 3D?
Yet cities look like this
Why 3D?
Across all industries ArcGIS users are going 3D to:•Visualize within the context of the real world
•Present with more realism and remove interpretation
Future Scenarios Thematic Info Analytic Results
Pictometry
Virtual Cities

Analytics: Shadow Impact
3D Shadow Analysis
• Impacts of building shadows- Detracts sunlight from public spaces
- Reduces solar potential
- Heat reduction effects on impervious surfaces
• Importance for planning- Adhere to regulations
- Maximize positive effects of sunlight and shading
- Communicate potential changes to public
3D Shadow Analysis
• Create “shadow fan” maps- Shows time per day spent in shadow
- Takes terrain variation into account
• Summarize results- Determine net shadow impact (m2hrs)
- Percent change

Analytics: Solar Potential
Solar Potential Analysis
• Why- Evaluate solar potential of built environment
- Offset carbon impact of new development
- Set rules for future urban design proposals
Solar Potential Analysis
• How - Determine best-fit atmospheric
parameters
- Create calculation surfaces
- Apply radiation output to roof faces
- Evaluate output - Find most suitable solar locations
- Evaluate impact of high-rise development
Solar Potential Analysis
• How - Determine best-fit atmospheric
parameters
