Introduction and Overview
A Survey of Remote Sensing Applications
1. What IS remote sensing?2. Name some advantages and disadvantages of
viewing the earth from progressively higher altitude.
3. Why is the sky blue at noon and orange at sunset?4. If light travels in a straight line,why aren’t shadows
pitch black?5. How can you use remote sensing to map elevation?6. How do the police measure your speed with radar?7. Why is water black in satellite images (it really is!)?8. What is a pixel and how does a computer make an
image from a bunch of them?
