2.6.1. Data Acquisition

Try these first

1. 1.

   What is data acquisition in the context of remote sensing?

   Hint

   Think about how we gather data from the sensors.

2. 2.

   What is the purpose of radiometric correction?

   Hint

   How does it improve the captured image?

3. 3.

   What is data acquisition?

   • Capturing data from sensors
   • Analyzing data types
   • Collecting user feedback

   Hint

   Think about how we gather information remotely.

4. 4.

   True or False: Radiometric correction aims to enhance color vibrancy in images.

   • True
   • False

   Hint

   What is the main goal of this correction?

5. 5.

   A remote sensing analyst attempts to overlay two images of the same area taken at different times. However, there are significant misalignments. Discuss how geometric correction could resolve these issues.

   Hint

   Think about the importance of perspective alignment in different images.

6. 6.

   An environmental scientist collects satellite data that appears very noisy and inconsistent. Detail the preprocessing steps they should apply, explaining the purpose of each.

   Hint

   What steps would you take to make a blurry picture clearer?
