5.12. Different Types of Resolutions

Try these first

1. 1.

   What is spatial resolution?

   Hint

   Think about how much detail you can see in a picture.

2. 2.

   Define spectral resolution.

   Hint

   Consider how colors reflect light differently.

3. 3.

   What does spatial resolution measure?

   • Size of the largest object
   • Smallest distinguishable size
   • Color variation

   Hint

   Consider how close two objects can be before they look like one.

4. 4.

   True or False: Higher radiometric resolution allows a sensor to capture more intensity levels.

   • True
   • False

   Hint

   Think about how many shades a color can have.

5. 5.

   Given a satellite with different spatial resolution settings, evaluate how a resolution of 30m compares to 1m in identifying urban structures.

   Hint

   Consider how satellite images show city blocks.

6. 6.

   Assess the impact of varying radiometric resolutions on analyzing surface temperature from thermal infrared data.

   Hint

   Think about temperature readings you would want to differentiate.
