Try these first

1. 1.

   What does DEM stand for?

   Hint

   Think about elevation data.

2. 2.

   Name one use of viewshed analysis.

   Hint

   Consider what needs to be seen from a point.

3. 3.

   What is a Digital Elevation Model (DEM)?

   • A 3D representation of Earth's surface elevation.
   • A method to analyze vegetation.
   • A technique for detecting water bodies.

   Hint

   Focus on what a model like DEM truly represents.

4. 4.

   Viewshed analysis is important for which application?

   • True
   • False

   Hint

   Consider how visibility affects building placement.

5. 5.

   Using a DEM, plan the layout of a new park in an area with varying elevation. Discuss your considerations regarding accessibility and visibility.

   Hint

   Think about the key features of the land that could influence your design choices.

6. 6.

   Analyze how a 3D city model could improve emergency response in a rapidly growing urban area. Identify specific features that would aid first responders.

   Hint

   How do spatial representations help with logistical planning?
