What technology does the acronym LiDAR represent?

• A. Light identification and detection analysis
• B. Light detection and ranging technology
• C. Laser imaging and digital assessment
• D. Low-intensity detection and response

Answer: (B)

LiDAR stands for Light Detection and Ranging. This technology uses laser light to measure distances to a target, which allows for the creation of precise, three-dimensional information about the shape of the Earth and its surface characteristics. It works by sending out laser pulses and measuring the time it takes for the light to reflect back from the target. This data can be used in various applications, including topographic mapping, forestry, environmental monitoring, and civil engineering. The other options do not accurately capture the full meaning of LiDAR. The use of "identification" or "assessment" in different context limits the actual technology's core function, which focuses on the measurement of distance through light pulses. The acronym itself emphasizes both the light aspect and the distance measurement capabilities that enable its wide-ranging applications in science and engineering.
