Physical Geography
Lidar, which stands for Light Detection and Ranging, is a remote sensing technology that uses laser pulses to measure distances and create high-resolution maps of the Earth's surface. By sending out laser light and recording the time it takes for the light to bounce back, lidar can gather detailed information about the topography, vegetation, and other features of an area. This technology plays a crucial role in geographic information systems (GIS) and remote sensing by providing precise data for analysis and visualization.
congrats on reading the definition of lidar. now let's actually learn it.
