7.3.7. Heat Maps (Density Maps)

Try these first

1. 1.

   What is a heat map?

   Hint

   Think about what colors represent on a map.

2. 2.

   Identify one application of heat maps.

   Hint

   Consider where we see maps displayed in public safety.

3. 3.

   What does a heat map primarily represent?

   • Absolute values
   • Data density
   • Sample size

   Hint

   Recall how heat maps visualize data occurrences.

4. 4.

   True or False: Heat maps can only visualize temperature data.

   • True
   • False

   Hint

   Think of different applications of heat mapping.

5. 5.

   Given a dataset of traffic accident locations within a city, design a heat map that identifies key accident hotspots. Describe what tools and processes you would use.

   Hint

   Think about the software's capabilities and the data's characteristics.

6. 6.

   Explain how one should interpret a heat map, considering different color gradients. Provide an example based on environmental data.

   Hint

   Consider the context of the data represented visually.
