2.6. Data Acquisition and Processing

Try these first

1. 1.

   What is data acquisition?

   Hint

   Think about the first steps in remote sensing.

2. 2.

   Why is radiometric correction important?

   Hint

   What affects the clarity of the data captured?

3. 3.

   What does data acquisition involve in remote sensing?

   • A. Capturing and storing data
   • B. Analyzing data
   • C. Presenting data

   Hint

   Consider the purpose before analysis.

4. 4.

   True or False: Geometric correction improves image visibility.

   • True
   • False

   Hint

   Think about the goals of geometric vs. enhancement processes.

5. 5.

   Consider a satellite image taken over a densely populated urban area affected by haze. Discuss the challenges of radiometric correction in this scenario.

   Hint

   Think about how atmospheric conditions can affect image clarity.

6. 6.

   You have satellite data that appears distorted due to the movement of the satellite. Outline the steps you would take to perform geometric correction.

   Hint

   Consider how referencing helps align the data.
