Question 210 pts


If you were told that the red in the Landsat image above represents reflectance in the near-infrared band, which of the following would you conclude?

Each red spot that you can discern in the image is 30 meters square.

The human eye perceives near-infrared radiation as the color red.

The red areas indicate water-filled retention ponds.

Healthy plant growth would be found if the red areas were visited in person.

Question 310 pts

What is a panchromatic image?

An image that is made up of all the colors of the spectrum.

A black and white image.

An image produced by a sensor which is sensitive to a broad range of wavelengths, including the entire visible band.

An image produced by a sensor which is sensitive to a narrow range of wavelengths, such as the gray band.

Question 910 pts

What is the difference between an active sensor and a passive sensor?

Passive sensors follow geostationary orbits in which they are positioned over the same ground locations at all times. Active sensors follow near-polar orbits that pass over every point on the Earth every 16 days.

Active sensors both transmit and measure electromagnetic energy. Passive sensors only measure it.

Passive sensors have no defense against enemy attack. Active sensors self-destruct during hijack attempts.

Active sensors actively transmit measurements to ground stations, whether the personnel on duty want the data or not. Passive sensors wait patiently until data are requested.

Question 1010 pts

What is the key advantage of multispectral remote sensing over panchromatic imaging?

Objects that are too small to be detected in panchromatic imagery can be discerned in more detailed multispectral imagery.

Objects that are indistinguishable in the visible band of the electromagnetic spectrum may be easy to tell apart at other wavelengths.

Multispectral imagery can be processed and analyzed digitally. Panchromatic images are just photographs.

Multispectral imagery has greater bit depth than panchromatic imagery.
