5.13.2. Based on internal geometry

Try these first

1. 1.

   What is a pushbroom scanner?

   Hint

   Focus on how the image is captured.

2. 2.

   Name one advantage of whiskbroom systems.

   Hint

   Consider what detail means in image capturing.

3. 3.

   What is a characteristic of pushbroom scanners?

   • Capture data pixel by pixel
   • Capture line by line
   • Only work in daylight

   Hint

   Think about the sequencing of how data is collected.

4. 4.

   True or False: Whiskbroom systems capture data simultaneously across all pixels.

   • True
   • False

   Hint

   Focus on the timing nature of data collection.

5. 5.

   Imagine a scenario where a pushbroom scanner and whiskbroom scanner are both used to map a new urban area. Discuss how the results may differ based on their geometries. What factors would influence the accuracy and reliability of the data?

   Hint

   Consider what aspects of each scanner's method lend to their pros and cons.

6. 6.

   Construct a scenario in which the internal geometric configuration of a sensor could lead to misleading data interpretation in a remote sensing application. Detail why this occurs.

   Hint

   Analyze how timing issues affect data integrity and interpretation.
