LiDAR Remote Sensing

An introduction to LiDAR remote sensing, including the principles of laser ranging and the use of LiDAR data for terrain mapping and 3D modeling.

What is the purpose of Lidar?

- "Lidar is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver."

How does Lidar operate?

- "Lidar may operate in a fixed direction (e.g., vertical) or it may scan multiple directions, in which case it is known as Lidar scanning or 3D laser scanning."

What are the applications of Lidar?

- "Lidar has terrestrial, airborne, and mobile applications." - "Lidar is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swathe mapping (ALSM), and laser altimetry."

In what fields can Lidar be used?

- "Lidar has applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swathe mapping (ALSM), and laser altimetry."

What are the capabilities of 3D laser scanning?

- "3D laser scanning is a special combination of 3-D scanning and laser scanning."

How is Lidar used in mapping?

- "Lidar is commonly used to make high-resolution maps." - "It is used to make digital 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light."

What are Lidar's applications in autonomous vehicles?

- "It has also been increasingly used in control and navigation for autonomous cars."

What are Lidar's applications in space exploration?

- "It has also been used for the helicopter Ingenuity on its record-setting flights over the terrain of Mars."

What is the full form of Lidar?
