(5 pts) How does file size (in megabytes) change as a function of increasing spatial resolution? How does it change as function of increasing spectral resolution?

(Hint: With the increase in spectral resolution this is a 1 to 1 relationship. With increase in spatial resolution: 20x20m = 1 pixel, 10x10m = 4 pixels, 5x5m = 16 pixels, 2x2m = 100 pixels, 1x1 = 400 pixels. What is the relationship here?)

Solution

File size is deteemined by no of pixles the image contains.

Spatial resolution relates to the number of pixels in the spatial measurement of the images. And in simple words spatial resolution is defined a snumber of independent pixels per inch.

Spectral resolution:

Its ability to resolve spectral features and bands into their separate component\'s.if the resolution is too high,spectral information will be good,if resolution is low,spectral will be lost preventing correct identification.

With increase in file size,the spectral resolution as 1-1relation it reduce the image resolution .
