Which technology is commonly used for remote sensing of deforestation?

  1. LiDAR

  2. RADAR

  3. GIS

  4. GPS


Correct Option: A
Explanation:

LiDAR (Light Detection and Ranging) is a remote sensing technology that uses lasers to measure the distance between the sensor and the ground. It is commonly used for creating detailed maps of the Earth's surface, including forests, and can be used to detect changes in forest cover over time.

What is the primary benefit of using remote sensing for monitoring deforestation?

  1. Cost-effectiveness

  2. Real-time monitoring

  3. Accurate measurements

  4. Wide-area coverage


Correct Option: D
Explanation:

Remote sensing allows for the monitoring of large areas of forest, which would be impractical or impossible to monitor using traditional methods such as ground surveys. This enables the detection of deforestation activities over extensive regions.

  1. Multispectral imaging

  2. Hyperspectral imaging

  3. SAR (Synthetic Aperture Radar)

  4. Thermal imaging


Correct Option: C
Explanation:

SAR (Synthetic Aperture Radar) is a remote sensing technique that uses radar signals to create images of the Earth's surface. It is particularly useful for detecting changes in forest cover, as radar signals can penetrate through clouds and vegetation.

How does remote sensing contribute to the monitoring of illegal logging activities?

  1. Detecting changes in forest cover

  2. Identifying areas of high deforestation risk

  3. Tracking the movement of logging equipment

  4. Monitoring the transportation of illegal timber


Correct Option: A
Explanation:

Remote sensing can detect changes in forest cover, which can indicate the occurrence of illegal logging activities. By comparing satellite images taken at different times, it is possible to identify areas where forests have been cleared or degraded.

Which technology is used to collect real-time data on deforestation activities?

  1. GPS (Global Positioning System)

  2. GIS (Geographic Information System)

  3. UAVs (Unmanned Aerial Vehicles)

  4. LiDAR (Light Detection and Ranging)


Correct Option: C
Explanation:

UAVs (Unmanned Aerial Vehicles), also known as drones, can be equipped with cameras or sensors to collect real-time data on deforestation activities. They can fly over large areas of forest and capture high-resolution images or videos, which can be used to detect and monitor deforestation in near real-time.

How does remote sensing technology assist in the enforcement of forest conservation laws?

  1. Identifying areas for conservation

  2. Monitoring compliance with regulations

  3. Detecting illegal activities

  4. Assessing the effectiveness of conservation efforts


Correct Option: B
Explanation:

Remote sensing technology can be used to monitor compliance with forest conservation laws by detecting changes in forest cover. By comparing satellite images taken at different times, it is possible to identify areas where forests have been cleared or degraded in violation of regulations.

Which remote sensing technique involves the use of multiple sensors to collect data on different aspects of forest ecosystems?

  1. Multispectral imaging

  2. Hyperspectral imaging

  3. SAR (Synthetic Aperture Radar)

  4. Thermal imaging


Correct Option: B
Explanation:

Hyperspectral imaging is a remote sensing technique that involves the use of multiple sensors to collect data on different wavelengths of light. This allows for the identification and classification of different types of vegetation and land cover, including forests.

  1. Identifying areas of high biodiversity

  2. Monitoring changes in species distribution

  3. Assessing the impact of deforestation on ecosystem services

  4. Quantifying carbon emissions from deforestation


Correct Option: B
Explanation:

Remote sensing technology can be used to monitor changes in species distribution by tracking changes in forest cover and habitat. By analyzing satellite images and other remote sensing data, it is possible to identify areas where forests have been cleared or degraded, and to assess the impact of these changes on the distribution of plant and animal species.

Which remote sensing technique involves the use of thermal sensors to detect changes in forest temperature?

  1. Multispectral imaging

  2. Hyperspectral imaging

  3. SAR (Synthetic Aperture Radar)

Correct Option: D
Explanation:

Thermal imaging is a remote sensing technique that involves the use of thermal sensors to detect changes in the temperature of the Earth's surface. It can be used to identify areas where forests have been cleared or degraded, as these areas often exhibit different thermal properties compared to intact forests.

How does remote sensing technology contribute to the quantification of carbon emissions from deforestation?

  1. Estimating the amount of biomass lost

LiDAR (Light Detection and Ranging) is a remote sensing technique that involves the use of satellite imagery to measure the height of trees. LiDAR sensors emit pulses of laser light and measure the time it takes for the light to bounce back from the ground and the tops of trees. This information can be used to create detailed maps of forest canopy height.
