3.2.1. Radiometric Correction

Try these first

1. 1.

   What is radiometric correction?

   Hint

   Think about adjustments for accurate readings.

2. 2.

   Why are Digital Numbers important in remote sensing?

   Hint

   Consider what DNs signify in terms of data.

3. 3.

   What is the primary purpose of radiometric correction?

   • To enhance image color
   • To remove sensor irregularities
   • To increase spatial resolution

   Hint

   Think about what we need to correct for accurate readings.

4. 4.

   True or False: Radiometric correction improves the ability to compare satellite images over time.

   • True
   • False

   Hint

   Consider why standardization matters for comparisons.

5. 5.

   Analyze a situation where inaccurate radiometric correction could lead to detrimental environmental consequences.

   Hint

   Consider how decisions affecting the environment rely on accurate data.

6. 6.

   Evaluate the importance of using multiple radiometric correction methods together. What could be a potential outcome of depending solely on one method?

   Hint

   Think about redundancy in processes and its benefits.
