  1. ArcGIS for 3D Cities: An Introduction Brian Sims Dan Hedges Thorsten Reitz

  2. ArcGIS for 3D Cities: An Introduction Go 3D with your GIS • 75 minute presentation • Beginners to GIS Jedi Masters • Speakers: • Brian Sims • Dan Hedges • Thorsten Reitz

  3. Technical Session Overview Go 3D with Your GIS • Why 3D? • Introduction to 3D Cities • 3D-Enabling Your GIS • Understanding through 3D Analytics: • Shadow Analysis • Solar Potential • View Quality • Sharing Your 3D City • Using + Extending the Living Atlas • Wrap Up + Questions

  4. Why 3D?

  5. Why 3D? Traditionally we manage our cities like this…

  6. Why 3D? Yet cities look like this

  7. 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 Thematic Info Virtual Cities Analytic Results Future Scenarios Pictometry

  8. 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 • Communicate with non-technical audiences

  9. 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 • Communicate with non-technical audiences • Drive more informed decisions faster

  10. Introduction to 3D Cities

  11. Helping you go 3D with your GIS Introduction to ArcGIS for 3D Cities Collection of best practices workflow: • Step-by-step workflows • Tools • Sample data • Example scenes http://esriurl.com/3DCities

  22. Analytics: Shadow Impact Dan Hedges

  23. 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

  24. 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

  25. Shadow Web Scene

  26. Analytics: Solar Potential Dan Hedges

  27. Solar Potential Analysis • Why • Evaluate solar potential of built environment • Offset carbon impact of new development • Set rules for future urban design proposals

  28. 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

  29. Solar Potential Analysis • How • Determine best-fit atmospheric parameters • Create radiation surface • Apply radiation output to roof faces • Evaluate output • Find most suitable solar locations • Evaluate impact of high-rise development

  30. Solar Potential Analysis • How • Determine best-fit atmospheric parameters • Create radiation surface • Apply radiation output to roof faces • Evaluate output • Find most suitable solar locations • Evaluate impact of high-rise development

  31. Solar Potential Analysis • How • Determine best-fit atmospheric parameters • Create radiation surface • Apply radiation output to roof faces • Evaluate output • Find most suitable solar locations • Evaluate impact of high-rise development
