What term describes how often imagery is captured over a given area, enabling change detection?

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

Answer: (B)

Temporal resolution refers to how often imagery of the same area is captured. This frequency determines how quickly you can observe changes and detect events. High temporal resolution lets you see rapid developments and pinpoint when changes occur, which is essential for effective change detection. In contrast, spectral resolution is about the number and width of wavelength bands, spatial resolution is about the level of detail or pixel size, and radiometric resolution is about the number of brightness levels recorded.
