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

Why 3D?



•Communicate with non-technical audiences

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


• 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



parameters

- Create radiation surface
