Satellite observation of the Earth provides many advantages over aircraft-borne sensors. Consider fields such as agronomy, forestry, or hydrology. For one such field of study, list some advantages . Can you suggest any disadvantages?
2. All remotely sensed images observe the Earth from above. Can you list some advantages to the overhead view (as opposed to ground-level views) that make remote sensing images inherently advantageous for many purposes? List some disadvantages to the overhead view.
3. Remotely sensed images show the combined effects of many landscape elements, including vegetation, topography, illumination, soil, drainage, and others. In your view, is this diverse combination an advantage or a disadvantage? Explain.
4. List ways in which remotely sensed images differ from maps. Also list advantages and disadvantages of each. List some of the tasks for which each might be more useful.
5. Some streetlights are deliberately manufactured to provide illumination with a reddish color., can you suggest why?
6. The human visual system is most nearly like which model of remote sensing .
