Overview
Importance of 3D Models in Spatial Analysis
In the previous lesson, you created a 3D map of the University Park campus. You learned how to symbolize layers based on procedural rule packages. In this lesson, you will learn two types of 3D spatial analysis. First, you will demonstrate the buildings that are affected in the case of a thunderstorm and a flash flood in State College. Second, you will learn how to do Sun Shadow analysis. It will give you a visual sense of how different sun positions will create various shadow volumes in different directions. It is a useful tool for building design and understanding the sun’s path in a given coordinate and also for figuring out the surface area that a building shades during a day.
Learning Outcomes
By the end of this lesson, you should be able to:

- Analyze the visibility of buildings and locations
- Calculate line of sights
- Calculate viewsheds
- Create layers
- Explore panning, zooming, and tilting
- Choose buildings and search for them
- Apply rules to extruded features
- Calculate, for example, a flood layer
- Share your work on Google Earth
