Try these first

1. 1.

   What is buffering in GIS?

   Hint

   Think about how we assess the area around a river.

2. 2.

   Name one use of interpolation in GIS.

   Hint

   Consider how we can predict rainfall amounts.

3. 3.

   What is the purpose of buffering in GIS?

   • To combine data layers
   • To create zones around features
   • To estimate unknown values

   Hint

   Think about zones of influence.

4. 4.

   True or False: Network analysis is not related to transportation systems.

   • True
   • False

   Hint

   Network analysis deals with connections.

5. 5.

   Design a GIS analysis plan that uses buffering and overlay analysis to assess urban flood risks. Outline the steps you would take and data layers needed.

   Hint

   Start with identifying relevant data layers.

6. 6.

   How would you use interpolation in a GIS project to manage water resources? Provide a scenario and the implications of your findings.

   Hint

   Think about predicting trends from scattered data points.
