The observations made over the same area on different dates to monitor ground features like crop growth is called
Show Hint
Remember the four resolutions in remote sensing:
• Spatial $\rightarrow$ Size of object detected.
• Spectral $\rightarrow$ Number and width of wavelength bands.
• Radiometric $\rightarrow$ Sensitivity to energy differences.
• Temporal $\rightarrow$ Frequency of image acquisition.
• Spatial $\rightarrow$ Size of object detected.
• Spectral $\rightarrow$ Number and width of wavelength bands.
• Radiometric $\rightarrow$ Sensitivity to energy differences.
• Temporal $\rightarrow$ Frequency of image acquisition.

The Correct Option is A
Solution and Explanation
Concept:
Temporal resolution is the frequency with which a remote sensing satellite revisits and acquires images of the same area.
It is useful for monitoring changes over time such as:
• Crop growth.
• Deforestation.
• Floods.
• Urban expansion.
Step 1: Understand temporal resolution. Repeated observations of the same location at regular time intervals enable monitoring of changes occurring on the Earth's surface.
Step 2: Differentiate from other resolutions.
• Spatial resolution $\rightarrow$ Smallest object that can be detected.
• Spectral resolution $\rightarrow$ Ability to distinguish wavelength bands.
• Radiometric resolution $\rightarrow$ Ability to detect small differences in energy.
• Temporal resolution $\rightarrow$ Frequency of repeated observations. Hence, \[ \boxed{\text{Repeated observations over time are described by temporal resolution}.} \] Therefore, the correct option is \[ \boxed{(A)\;\text{Temporal resolution}.} \]
