  1. Aeronautics engineers

  2. Space scientists

  3. Map makers

  4. Photographers

Show answer
Correct Option: C
Explanation:

Aerial photographs were the first result of remote sensing utilized by the cartographers, or map makers. In 1858, French map-makers used a hot air balloon and primitive cameras to take inclined aerial photographs of the landscape.

The second revolution in remote sensing technology began with the launch of ____.

  1. TIROS-1

  2. LANDSAT

  3. ERTS

  4. SPOT

Show answer
Correct Option: C
Explanation:

In the 1970s, the second revolution in remote sensing technology began with the launch of ERTS (Earth Resource Technology Satellite.) This series was renamed LANDSAT in 1975.

  1. 1983

  2. 1985

  3. 1986

  4. 1989

Show answer
Correct Option: C
Explanation:
  • SPOT was launched on February 22, 1986 and decommissioned on December 31, 1999. 
  • The SPOT orbited 5 satellites from 1986 to 2015, revealing Earth’s surface in increasing detail and paving the way for a plethora of applications including mapping, vegetation monitoring, land use and land cover, and the impacts of natural disasters.

  1. El-Nino effect

  2. CFC releases

  3. Cyclones in the Bay of Bengal

  4. Rains in the Himalayan region

Show answer
Correct Option: A
Explanation:

El-Nino derived from Spanish means 'the child',i.e. baby christ. A warm ocean current that flows over Peru is an interval of two to five years.

After energy has been emitted by the target, the sensor collects and records the _____.

remote sensing remote sensing eyes in the sky and data analysis mapping skills geography

  1. Sunrays

  2. Objects on Earth

  3. Electromagnetic radiation

  4. None of these

Show answer
Correct Option: C
Explanation:
  • Once the energy makes its way to the target through the atmosphere, it interacts with the target depending on the properties of both the target and the radiation.
  • After the energy has been scattered by, or emitted from the target, we require a sensor (remote - not in contact with the target) to collect and record the electromagnetic radiation.
