Converting DN values to radiance values is an operation of
A) filtering
B) linear stretching
C) radiometric correction
D) geometric correction

Question

Quizplus · Accepted Answer

Converting DN values to radiance values involves applying a radiometric correction, which takes into account sensor and atmospheric effects to produce values in units of radiance (e.g. watts per square meter per steradian). Filtering and geometric correction refer to other types of image processing operations, while linear stretching involves adjusting the dynamic range of the image without changing its fundamental values or units.
