Quiz 4- Remote Sensing

The visible wavelengths cover a range from approximately 0.4 to 0.7 µm. The longest visible wavelength is blue and the shortest is violet.

• TRUE

• FALSE

The longer the wavelength, the lower the frequency. The shorter the wavelength, the lower the frequency.

• TRUE

• FALSE

The temperature of the object decreases, its dominant wavelength shifts towards the shorter wavelength portion of the spectrum.

• TRUE

• FALSE

Absorbs the harmful ultraviolet radiation from the sun

Absorbs radiation strongly in the far infrared portion of the spectrum - that area associated with thermal heating - which serves to trap this heat inside the atmosphere

Sensor which measures energy that is naturally available from the target.

provide their own energy source for illumination.

Type of Spectral resolution which produce black & white image

Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points.

• TRUE

• FALSE

Remote sensing is the process of obtaining information about earth's surface from measurements of radiated energy by aircraft or satellite sensors.

• TRUE

• FALSE
