13.10. Error Handling in Remote Sensing and Image Processing

Try these first

1. 1.

   What is the difference between geometric and radiometric errors?

   Hint

   Consider the effects they have on an image.

2. 2.

   Name one common cause of geometric distortion.

   Hint

   Think about the Earth's shape.

3. 3.

   What are geometric errors primarily associated with?

   • Pixel brightness
   • Spatial representation
   • Atmospheric conditions

   Hint

   Think about what geometry entails.

4. 4.

   True or False: Radiometric errors affect the spatial accuracy of images.

   • True
   • False

   Hint

   Consider what radiometry encompasses.

5. 5.

   Describe a scenario where both geometric and radiometric errors could affect a remote sensing project. How would you approach correcting these errors?

   Hint

   Break down your problem-solving approach step-by-step.

6. 6.

   Consider a satellite image captured at noon and another at sunset. Explain how sun angle variation might create radiometric errors and how you can correct this.

   Hint

   Think about why different times of the day would change brightness levels.
