B.S.F. or B.Sc.F. Bachelor of Science in Forestry Bachelor of Science in Forestry: Remote Sensing and GIS in Forestry 1

Question 1

What does the acronym GIS stand for in the context of forestry applications?

Accepted Answer

Geographic Information System

Answer

GIS stands for Geographic Information System, a framework for capturing, managing, analyzing, and visualizing spatial and geographic data used extensively in forestry planning.

Question 2

Which electromagnetic spectral band is most commonly used in remote sensing to detect healthy green vegetation?

Accepted Answer

Near-infrared (NIR)

Answer

Near-infrared (NIR) radiation is strongly reflected by chlorophyll-rich, healthy plant tissue, making it the most useful band for detecting and assessing living vegetation.

Question 3

What does NDVI stand for in forest remote sensing?

Accepted Answer

Normalized Difference Vegetation Index

Answer

NDVI (Normalized Difference Vegetation Index) is calculated from red and near-infrared bands to quantify vegetation density and health across large forested areas.

Question 4

LiDAR technology in forestry is primarily valued for its ability to measure which forest attribute with high accuracy?

Accepted Answer

Canopy height and vertical structure

Answer

LiDAR (Light Detection and Ranging) emits laser pulses and measures return times to produce precise three-dimensional data on canopy height and vertical forest structure.

Question 5

Which of the following Landsat satellite series is operated jointly by NASA and the USGS and is widely used for long-term forest cover monitoring?

Accepted Answer

Landsat 8/9

Answer

Landsat 8 and Landsat 9, operated by NASA and USGS, provide continuous 30-meter resolution imagery dating back to 1972, making them the standard for long-term forest change detection.
