3.6.2. Ground Truthing

Try these first

1. 1.

   What is ground truthing?

   Hint

   Think about how we check if data from satellites matches reality.

2. 2.

   Name one tool used in ground truthing.

   Hint

   This tool helps us know where we are when collecting data.

3. 3.

   What is the primary purpose of ground truthing?

   • To collect images from satellites
   • To validate satellite classifications
   • To enhance data collection processes

   Hint

   Think about the verification process in scientific studies.

4. 4.

   True or False: Ground truthing can only be performed in urban areas.

   • True
   • False

   Hint

   Consider the range of applications for remote sensing.

5. 5.

   Evaluate a case study where ground truthing significantly altered the results of a satellite classification project. Discuss what the initial assumptions were and how ground truthing provided more accurate insights.

   Hint

   Consider what assumptions led to the classification and how field data shifted perspectives.

6. 6.

   Design an optimal ground truthing strategy for a satellite project focused on urban development, detailing steps to ensure comprehensive validation of classifications.

   Hint

   Think about practical steps you would need to take to collect real-world data effectively.
