Geospatial and Monitoring Technology Questions

Multiple choice

Which remote sensing technique involves the use of satellite imagery to quantify the amount of carbon sequestered by forests?

  1. Multispectral imaging

  2. Hyperspectral imaging

  3. LiDAR (Light Detection and Ranging)

  4. SAR (Synthetic Aperture Radar)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Multispectral imaging is a remote sensing technique that involves the use of satellite imagery to quantify the amount of carbon sequestered by forests. Multispectral images are captured using sensors that detect light in multiple bands of the electromagnetic spectrum, including visible light and near-infrared light. These images can be used to estimate the amount of biomass in forests, which can then be used to calculate the amount of carbon sequestered.
