Which of the following is NOT one of the resolutions of remote sensing?

The correct answer is digital, as it does not represent one of the traditional resolutions of remote sensing. In remote sensing, the three primary resolutions are spatial, spectral, and temporal.

Spatial resolution refers to the detail, or the level of detail, of a specific observation, often indicated by the size of the smallest object that can be detected in an image. A higher spatial resolution means more detailed images.

Spectral resolution relates to the ability of a sensor to discriminate between different wavelengths of light. It defines how many spectral bands a sensor can detect, which is crucial for identifying materials based on their spectral signatures.

Temporal resolution indicates how frequently a sensor can capture images of the same area over time. This is particularly important for monitoring changes, such as vegetation growth or urban development, as it helps understand trends and dynamics in the observed phenomena.

Digital, however, usually pertains to the format or processing of data rather than a resolution of the remote sensing process itself. While digital technologies enhance the capabilities of remote sensing systems and improve data processing, they do not qualify as a resolution category like the others do.
