Try these first

1. 1.

   What type of data does hyperspectral remote sensing collect?

   Hint

   Think about the range of wavelengths.

2. 2.

   What is the primary application of thermal infrared remote sensing?

   Hint

   Consider what it measures.

3. 3.

   What is the primary purpose of hyperspectral remote sensing?

   • To capture images in visible light
   • To detect materials with narrow spectral bands
   • To measure temperatures

   Hint

   Look for the key term 'hyperspectral'.

4. 4.

   Is thermal infrared remote sensing used for analyzing surface temperatures?

   • True
   • False

   Hint

   What does thermal refer to in this context?

5. 5.

   Assess the advantages of using LiDAR over traditional surveying methods in urban contexts. Provide a comparative analysis.

   Hint

   Think about the speed and precision of LiDAR.

6. 6.

   Create a proposal outline, including methods and expected outcomes, for a project utilizing both hyperspectral sensing and SAR to manage flood risks in urban areas.

   Hint

   Focus on how the two technologies add value to the analysis.
