Satellite Sensor Resolutions Explained

The video tutorial explains the concept of resolution in satellite sensors, focusing on four types: spatial, radiometric, spectral, and temporal. Spatial resolution deals with the distance between objects, spectral resolution involves color and frequency detection, temporal resolution concerns time intervals between observations, and radiometric resolution measures intensity. The tutorial highlights the importance of each type in satellite imagery and provides examples to illustrate their applications.

What is the primary factor that resolution in satellite sensors determines?

• The color of the objects

• The distance between objects

• The speed of the satellite

• The detail in the imagery

Which type of resolution is concerned with the distance between two objects?

• Spatial resolution

• Temporal resolution

• Radiometric resolution

• Spectral resolution

What does spectral resolution primarily focus on?

• The time interval between images

• The intensity of light

• The frequency and sensitivity to light

• The distance between objects

Why is higher spectral resolution needed to identify shades of red?

• Because red is not visible to the human eye

• Because red is less sensitive to light

• Because red is a primary color

• Because shades of red have similar frequencies

What does temporal resolution help to determine?

• The color of objects

• The time interval between events

• The intensity of light

• The distance between objects

In temporal resolution, what is required when the time delay between two events is very short?

• A low resolution sensor

• A high resolution sensor

• A sensor with high intensity

• A sensor with low frequency

What aspect does radiometric resolution focus on?

• The time interval between images

• The distance between objects

• The intensity of light

• The frequency of light

How does a bright source of light affect radiometric resolution?

• It has no effect on the resolution

• It decreases the resolution

• It makes the resolution finer

• It makes the resolution coarser

Which satellite sensor provides a finer spatial resolution compared to Landsat?

• GOES

• NOAA

• SPOT HRV

• MODIS

What is the relationship between radiometric range and intensity?

• Higher range means higher intensity

• Range only affects color, not intensity

• Range and intensity are unrelated

• Higher range means lower intensity
