What type of resolution improves by imagery captured successively over time to detect changes in the landscape?

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

Answer: (C)

Temporal resolution is about how often you capture images of the same area. When imagery is collected successively over time, you create a timeline that lets you see what changes occurred from one moment to the next, which is essential for detecting how the landscape evolves. This frequent revisitation enables monitoring events like crop growth, deforestation, urban expansion, or flood changes, where timing and sequence matter.

Spatial resolution, on the other hand, refers to the smallest detail you can see in a single image—the level of detail on the ground. Radiometric resolution is about how finely the sensor can distinguish different brightness levels or intensities. Spectral resolution concerns how many and which wavelength bands the sensor records. While those aspects affect image quality and the type of information you can extract in each image, they do not inherently describe how often you revisit the same area to notice changes over time.
