1. Remote sensing is best defined as
A. Measurement of physical properties by direct contact
B. Acquisition of information about objects without physical contact
C. Ground surveying using instruments
D. Laboratory-based sample analysis
Answer: B
Rationale: Remote sensing collects data from a distance using sensors
without direct contact with the target.
2. The primary source of energy for passive remote sensing is
A. Radar pulses
B. The Sun
C. Thermal generators
D. Satellite batteries
Answer: B
Rationale: Passive sensors rely mainly on solar radiation reflected or
emitted from the Earth.
3. Which sensor type provides its own energy source?
A. Passive optical
B. Multispectral
C. Active sensor
, D. Thermal infrared
Answer: C
Rationale: Active sensors transmit energy and measure the reflected
signal.
4. Spatial resolution refers to
A. Number of spectral bands
B. Smallest object that can be resolved
C. Frequency of image capture
D. Radiometric sensitivity
Answer: B
Rationale: Spatial resolution describes the ground area represented by one
pixel.
5. Temporal resolution is the
A. Sensor wavelength range
B. Pixel size
C. Time between successive observations
D. Number of bits per pixel
Answer: C
Rationale: Temporal resolution indicates revisit frequency of a sensor.
6. Spectral resolution describes
A. Image clarity
B. Ability to distinguish wavelength intervals
C. Pixel depth
D. Swath width
Answer: B
Rationale: Higher spectral resolution means narrower wavelength bands.
7. Radiometric resolution refers to
A. Pixel size
B. Number of intensity levels recorded
C. Sensor altitude
D. Viewing angle
, Answer: B
Rationale: Radiometric resolution reflects sensor sensitivity to small
differences in energy.
8. Which wavelength region is most useful for vegetation analysis?
A. Blue
B. Red
C. Near-infrared
D. Thermal infrared
Answer: C
Rationale: Healthy vegetation strongly reflects near-infrared radiation.
9. NDVI is calculated using
A. Blue and green bands
B. Red and near-infrared bands
C. Thermal and red bands
D. Microwave and infrared
Answer: B
Rationale: NDVI exploits vegetation reflectance contrast between red and
NIR.
10.A Landsat satellite primarily provides
A. Radar data only
B. Multispectral optical imagery
C. Hyperspectral imagery exclusively
D. LiDAR data
Answer: B
Rationale: Landsat missions are known for multispectral Earth
observation.
11.Atmospheric scattering mainly affects which wavelengths?
A. Infrared
B. Microwave
