What is the difference between spatial resolution and temporal resolution?

Spatial resolution refers to the size of one pixel on the ground. Temporal resolution refers to the how often data of the same area is collected. This is typically referred to as Revisit Time.

What is the spatial resolution?

Spatial resolution is a measure of the smallest object that can be resolved by the sensor, or the ground area imaged for the instantaneous field of view (IFOV) of the sensor, or the linear dimension on the ground represented by each pixel.

What is the difference between IFOV and FOV in remote sensing?

The IFOV characterizes the sensor, irrespective of the altitude of the platform. The field of view (FOV) is the total view angle that defines the swath.

What determines angular resolution?

The angular resolution is proportional to the ratio of the wavelength, l, of the radiation divided by the telescope diameter: q = l/D. If you have 20/20 vision, your visual acuity is limited by the diameter of the pupil of your eye, and glasses cannot further improve that vision.

What is the relationship between spatial and temporal resolution?

On that account, two terms are introduced: spatial resolution, and temporal resolution. The spatial resolution is the amount of spatial detail in an observation, and the temporal resolution is the amount of temporal detail in an observation.

What is the difference among temporal and spatial and spectral and radiometric resolution?

Spectral Resolution refers to the ability of a satellite sensor to measure specific wavlengths of the electromagnetic spectrum. The finer the spectral resolution, the narrower the wavelength range for a particular channel or band. Temporal resolution refers to the time between images.

What is the difference between high and low spatial resolution?

Low and high spatial resolution The more pixels are included in a remote sensing image of a certain area, the higher the spatial resolution meaning the more details can be observed. You can clearly distinguish between a higher spatial resolution of 30 metres and a lower spatial resolution of 300 metres.

What is spatial resolution in remote sensing?

Spatial Resolution refers to the size of the smallest feature that can be detected by a satellite sensor or displayed in a satellite image. For example, a spatial resolution of 250m means that one pixel represents an area 250 by 250 meters on the ground.

What is FOV and Ifov?

Instantaneous field of view or (IFOV) is an important calculation in determining how much a single detector pixel can see in terms of field of view (FOV).

Why is angular resolution important?

The combination of physical size and distance, as expressed by angular size and angular resolution, is the important criterion for determining how well Hubble, other telescopes, or even the human eye will be able to see an object.

What is angular resolution of the human eye?

about 1 arcminute
The human eye has an angular resolution of about 1 arcminute (0.02 degrees or 0.0003 radians) which enables us to distinguish things that are 30 centimetres apart at a distance of 1 kilometre. “One of the stars that you see might actually be two stars that are separated by a really tiny angle,” says Allanach.
