11.1.2. Techniques Used

Try these first

1. 1.

   What is remote sensing?

   Hint

   Think about satellite imagery.

2. 2.

   Name one satellite that provides remote sensing imagery.

   Hint

   There are specific satellite names known for their surveying capabilities.

3. 3.

   What does remote sensing allow us to do?

   • Collect data remotely
   • Only collect data on land cover
   • Collect data without analysis

   Hint

   Think about distance data collection.

4. 4.

   True or False: Supervised classification operates without labeled data.

   • True
   • False

   Hint

   Consider what 'supervised' implies.

5. 5.

   Create a plan for implementing remote sensing in monitoring land use changes over several years. Include the classification method and expected challenges.

   Hint

   Think about the steps needed for a long-term project.

6. 6.

   Analyze the impacts of using unsupervised classification on accuracy in different types of land cover. Provide examples of possible errors.

   Hint

   Consider what happens when category boundaries are not clearly defined.
