Which of the following is a main source of remote sensing data?
- A. Groundwater well logs
- B. Satellites and aircraft
- C. Soil sample bottles
- D. Weather stations only
Answer: B. Satellites and aircraft
Remote sensing collects information about the Earth's surface using sensors on satellites and aircraft without direct contact.

Which of the following sequences is correct in a remote sensing process?
- A. Energy source → interaction with target → sensor records data
- B. Sensor records data → energy source → target interaction
- C. Target data → map printing → satellite launch
- D. Map analysis → energy source → field survey
Answer: A. Energy source → interaction with target → sensor records data
Remote sensing begins with an energy source, followed by interaction with the target, and then recording by the sensor.

Which statement is the most appropriate about GNSS?
- A. It depends on a single satellite only
- B. It provides precise position, velocity, and time using a constellation of satellites
- C. It is used only for printing maps
- D. It cannot function in transportation or surveying
Answer: B. It provides precise position, velocity, and time using a constellation of satellites
GNSS uses multiple satellites to provide accurate position, velocity, and timing information for navigation and surveying.
