What does "LiDAR" stand for in geographic data collection?

LiDAR stands for "Light Detection and Ranging." This technology uses laser light to measure distances between the sensor and the Earth's surface, collecting precise information about the topography and characteristics of the landscape. The technique works by sending out laser pulses and measuring the time it takes for the light to return after bouncing off the ground or other objects. This data can create high-resolution maps and models, making LiDAR an essential tool in geographic data collection for applications in surveying, forestry, environmental monitoring, and urban planning.

Understanding the definition of LiDAR is crucial as it highlights the role of light in technology and indicates its potential for capturing detailed elevation data, which is central to various GIS applications. Other options provided do not accurately represent the technology or its functions, making it clear why "Light Detection and Ranging" is the correct and widely accepted definition.
