What type of resolution determines whether fine detail can be distinguished in an image and the degree of detailed features of the object can be seen?

What type of resolution determines whether fine detail can be distinguished in an image and the degree of detailed features of the object can be seen?

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

Answer: (B)

The focus here is on how much fine detail an image can reveal, or how clearly adjacent features can be distinguished. That’s spatial resolution. It describes the level of detail and the smallest feature size the sensor can resolve, which is often described by the ground sample distance (GSD): the smaller the GSD, the finer the detail you can see. Other types of resolution cover different aspects: temporal resolution is about how frequently images are captured (revisit rate), spectral resolution is about how many and which wavelength bands are distinguished, and radiometric resolution is about how precisely brightness differences are recorded. So when the question asks about distinguishing fine detail and the degree of detectable features, spatial resolution is the determining factor.
