2.1. Basic Concepts of Remote Sensing

Try these first

1. 1.

   What is remote sensing?

   Hint

   Think about how we get information without being directly present.

2. 2.

   Name two components of remote sensing.

   Hint

   Think about what is needed to detect reflections or emissions.

3. 3.

   What is the definition of remote sensing?

   • A process to gather information through physical contact.
   • The acquisition of data about physical objects without contact.
   • The analysis of data exclusively from ground sources.

   Hint

   Focus on the key characteristic of remote sensing.

4. 4.

   True or False: Sensors are only used in spaceborne platforms.

   • True
   • False

   Hint

   Remember the different kinds of platforms.

5. 5.

   Propose a scenario where remote sensing could impact disaster management and explain how it would be implemented, including the components involved.

   Hint

   Consider how remote sensing provides timely information for crisis responses.

6. 6.

   Evaluate the significance of combining ground truth data with remote sensing data in achieving accurate results.

   Hint

   Reflect on why checking data accuracy is necessary in scientific research.
