Question

What is spatial resolution of the sensor?

• A. The size of the largest object on the Earth’s surface that a satellite sensor can distinguish.
• B. The size of the most pixelated object on the Earth’s surface that a satellite sensor can distinguish.
• C. The size of the least pixelated object on the Earth’s surface that a satellite sensor can distinguish.
• D. The size of the smallest object on the Earth’s surface that a satellite sensor can distinguish.

Answer 1

The correct option is D The size of the smallest object on the Earth’s surface that a satellite sensor can distinguish.

The size of the smallest object on the Earth’s surface that a satellite sensor can distinguish is called the spatial resolution of the sensor. Meteorologists, oceanographers, and geologists all use spatial data to visually explain the information that images and other data provide.
