Off-nadir viewing allows a sensor

B)to sense beyond the usual 8-bit range of values.
C)to image locations not directly under the sensor.
D)to image more than 100 bands simultaneously.

Question

Quizplus · Accepted Answer

Off-nadir viewing allows a sensor to image locations not directly under the sensor, meaning the sensor can capture images at angles other than straight down. This technique is particularly useful when imaging rugged terrains or urban areas, where direct overhead viewing may be obstructed by buildings or topographic features. It does not affect the sensor's ability to obtain high resolution or sense beyond the 8-bit range of values, nor does it increase the number of bands that can be imaged simultaneously.
