3.2.3. Atmospheric Correction

Try these first

1. 1.

   What is the primary purpose of atmospheric correction?

   Hint

   Think about how the atmosphere could affect the light reaching the sensor.

2. 2.

   Name one method used for atmospheric correction.

   Hint

   Remember the terms we've discussed in class.

3. 3.

   What does atmospheric correction aim to achieve?

   • Enhance image color
   • Eliminate atmospheric effects
   • Increase spatial resolution

   Hint

   Focus on the primary goal of this process.

4. 4.

   True or False: Dark Object Subtraction is a method used for image enhancement, not correction.

   • True
   • False

   Hint

   Recall the main purpose of each method discussed.

5. 5.

   Consider the implications of using satellite data without any atmospheric correction in a study of coastal erosion. What issues might arise?

   Hint

   Think about how clear distinctions in data are needed to assess changes accurately.

6. 6.

   Design a research project to compare the effectiveness of DOS versus FLAASH in correcting imagery for urban planning. Outline your approach and expected outcomes.

   Hint

   Focus on which method may provide more reliable data for planning purposes.
