11.2.3. 3D Terrain Modeling

Try these first

1. 1.

   What does a Digital Elevation Model (DEM) represent?

   Hint

   Think about what elevation data helps visualize.

2. 2.

   What do contour lines illustrate on a map?

   Hint

   Consider how these lines can show steepness.

3. 3.

   What type of data does a Digital Elevation Model (DEM) provide?

   • Color data
   • Elevation data
   • Temperature data

   Hint

   Consider what type of model represents landforms.

4. 4.

   True or False: Contours are necessary for understanding slope and elevation.

   • True
   • False

   Hint

   Think about their role in mapping.

5. 5.

   Design a theoretical route for a new highway in a hilly region using DEMs and contour data. Include potential challenges you might face and methods to overcome them.

   Hint

   Consider how DEMs help visualize challenges.

6. 6.

   Evaluate how modern 3D terrain modeling tools can aid in flood risk management in urban areas.

   Hint

   Think about what features show where water might accumulate.
