(a) How does the changing the enhancement curve from "unenhanced" (curve A) to curve B change a satellite image?  Give a specific example of how the same temperature is represented differently on the image by the different curves.
 
 
 
 
 
 

(b) How does  changing the enhancement curve from "unenhanced" (curve A) to curve C change a satellite image?  Give a specific example of how the same temperature is represented differently on the image by the different curves.

(a) How does the changing the enhancement curve from "unenhanced" (curve A) to curve B change a satellite image?  How is a temperature of -40 deg C represented differently (in terms of grey shades) on the image by the different curves? How is a temperature of about 20 deg C represented differently (in terms of grey shades) on the image by the different curves?
 
 
 
 
 
 

(b) How does  changing the enhancement curve from "unenhanced" (curve A) to curve C change a satellite image?  How is a temperature of -110 deg C represented differently (in terms of grey shades) on the image by the different curves? How is a temperature of about 55 deg C represented differently (in terms of grey shades) on the image by the different curves?

In the above figure, the ZA enhancement curve is shown by the solid black line. The unenhanced curve is shown by dashed lines where it deviates from the ZA curve. Explain how the different segments of the ZA curve would change an unenhanced satellite image in terms of how the following temperature ranges are represented by grey shades.

55 deg C to 29.4 deg C
 

29.2 deg C to 6.8 deg C
 

6.7 deg C to -55.7 deg C
 

-56.0 deg C to -75.2 deg C
 

-75.7 deg C to -110.3 deg C
