2.5.3. Sensor Resolutions

Try these first

1. 1.

   What does spatial resolution refer to?

   Hint

   Think about the clarity of the image.

2. 2.

   How does spectral resolution affect material identification?

   Hint

   More bands mean better distinction.

3. 3.

   What is spatial resolution?

   • Size of pixel
   • Energy sensitivity
   • Band width

   Hint

   Think about how big the area each pixel represents.

4. 4.

   True or False: Higher radiometric resolution allows for better discrimination of subtle energy differences.

   • True
   • False

   Hint

   Consider how sensitive the sensor is.

5. 5.

   Evaluate a scenario where monitoring urban development requires a balance of all four sensor resolutions. Discuss how deficiencies in one may impact the overall data accuracy.

   Hint

   Think about specific examples of urban features that might be overlooked.

6. 6.

   Design a remote sensing study that requires leveraging high spectral and radiometric resolutions. What applications would benefit, and what resolutions would you choose?

   Hint

   Consider differences in the light spectrum that plant species may reflect.
