Question

Which resolution refers to the smallest object that a sensor can detect?

• A. Spatial resolution
• B. Temporal resolution
• C. Radiometric resolution
• D. Spectral resolution

Hint:

Remote sensing resolutions: \[ \boxed{ \begin{aligned} \text{Spatial} &\rightarrow \text{Smallest object detected} \text{Spectral} &\rightarrow \text{Number of wavelength bands} \text{Temporal} &\rightarrow \text{Revisit time} \text{Radiometric} &\rightarrow \text{Sensitivity to energy levels} \end{aligned} } \]

Answer 1

The Correct Option is A

Spatial resolution is the size of the smallest ground feature that can be distinguished by a remote sensing sensor. A higher spatial resolution allows the detection of smaller objects. Hence, \[ \boxed{\text{Spatial resolution}} \] is the correct answer. Therefore, \[ \boxed{(A)} \]
