What are the advantages and disadvantages of using remote sensing?
Advantages• Can track changes
of an area over time• Do not actually have
to go to the area• Can collect data
from the area anytime
Disadvantages• Cannot test
conditions of the environment
• Cannot see detail• Cannot talk to
people who are there
![Page 26: 10/18/11 and 10/19/11](https://reader035.vdocument.in/reader035/viewer/2022062307/55825b98d8b42a09258b516b/html5/thumbnails/26.jpg)
What are the advantages and disadvantages of ground truthing?
Advantages• Test the conditions of
the environment• More detail regarding
the area can be observed
• Verify what remote sensing gathers
• Talk to people who are there
Disadvantages• Can only survey a
small area at a time• Cannot track change
of the area over a long period of time
• Can only collect data when area is safe

New Orleans. How could you use remote sensing and ground truthing to gather data and information about the hurricane and the damage it caused?

CONTEXT CLUES:1. I live in an urban area. There are big buildings,
busy streets, and lots of people that always seem to be busy!
2. He was so tired from school that he went straight home and fell asleep. When his mom got home, she found him sprawled across the couch with his backpack still on!
2. Her things were sprawled all across the floor. You could barely see the carpet when you walked into her room!
