QUESTION
Objective Question
The ability of remote sensing system to describe the smallest dimension on the Earth's surface
is called :
Answer
( Option A)
Spatial resolution
Solution
Spatial resolution : This refers specifically to the size of the smallest possible feature or area
on the Earth's surface that can be detected and distinguished as a distinct entity by a sensor.
Higher spatial resolution means smaller cell or pixel sizes, allowing for greater detail to be
observed.
Radiometric resolution : This describes the ability of a sensor to discriminate very
slightdifferences in electromagnetic energy or signal strength
Spectral resolution : This refers to the ability of a sensor to define fine wavelength intervals. A
higher spectral resolution means the sensor can distinguish between more narrow bands of
the electromagnetic spectrum.
Temporal resolution : This refers to the revisit time or frequency with which a satellite sensor
captures imagery of a particular area on the Earth's surface.
