What is the role of LiDAR in GIS?

LiDAR, which stands for Light Detection and Ranging, plays a crucial role in the field of Geographic Information Systems (GIS) due to its ability to create highly detailed and accurate topographical maps. This remote sensing technology utilizes laser light to measure distances between a sensor and the surface of the Earth. By sending out thousands of laser pulses per second and capturing the reflected signals, LiDAR generates precise elevation data, making it invaluable for terrain mapping, vegetation analysis, and urban planning.

The high-resolution maps produced by LiDAR encompass not only the ground surface but also canopy heights for vegetation and structures, which enhances the overall analytical capability of GIS. This precision allows for detailed modeling and analysis that supports various applications, from forestry and flood modeling to archaeological site analysis and infrastructure development.

Other options, while relevant to data collection or mapping, do not represent the specific characteristics and applications of LiDAR technology as effectively as the correct answer. While user surveys and ground-based data capture focus on gathering human perspectives or specific data capture methods, and storing remote camera footage relates more to video data management, they do not encompass the unique functionalities and advantages provided by LiDAR in GIS contexts.
