What Are the Different Uses of LiDAR Processing?
Mar 22, 2022
LiDAR (Light Detection and Ranging) technology and processing is used in a wide range of research and practical applications. With its ability to measure dimensions, distances, textures, and many other aspects of targeted subjects, LiDAR processing has become an increasingly important tool in geology, geography, surveying, agriculture, and forestry. Atmospheric sciences, archaeology, seismology, and geomatics also depend on data gathered using LIDAR processing for research, while physics and astronomy benefit from LiDAR's ability to create highly precise maps.
With its early adoption by atmospheric scientists, LiDAR processing marked one of the first uses of laser technology. LiDAR technology continues to be a critically important tool in studying the composition of the atmosphere and clouds. With increasing concern over greenhouse gases and other aerosol substances in the atmosphere, LiDAR processing enables scientists to precisely determine how much carbon dioxide, ozone, and other substances are present in the atmosphere.
In the earth sciences, LiDAR processing allows the detection of obscured topographic details, such as land elevations below dense vegetation. Repeated LiDAR surveys of specific locations have led to a greater understanding of the geological and chemical forces that result in changes on the Earth's surface. High-resolution maps generated via stationery and airborne LiDAR systems offer hydrologists new insights into subterranean water movement.
Aircraft-based LiDAR systems used in conjunction are used to defect faults in the Earth's crust and measure the upthrusts caused by tectonic activity. National Aeronautics and Space Administration (NASA) operates the Airborne Topographic Mapper that is used to both monitor glacier activity and coastal topography changes. This function has become increasingly important in disaster assessment. These same technologies are employed in soil studies that take advantage of LiDAR's ability to provide highly detailed models of the terrain being studied.

LiDAR and Hyperspectral Remote Sensing Data Fusion Realize Complementary Advantages
With the continuous development and progress of earth observation technology, and the continuous diversification of means for obtaining spatial information, the use of a single means of spatial data resources has been difficult to meet people's information needs. Lidar and hyperspectral Remote sensing, as two common Remote sensing methods, have different characteristics: Lidar can quickly, efficiently and accurately obtain three-dimensional spatial data of features, and hyperspectral images can well characterize the spectral information of features , Reflecting the characteristics of its features, materials, texture, etc. The fusion of these two kinds of data can achieve complementary advantages, maximize their respective characteristics, and achieve more accurate intelligent detection and identification of objects and higher-precision classification and extraction, which are widely used in forestry ecology, precision agriculture, environment Monitoring and other fields.

The Basics of LiDAR
LiDAR is an active Remote sensing system. An active system means that the system itself generates energy - in this case, light - to measure things on the ground. In a LiDAR system, light is emitted from a rapidly firing laser. You can imagine light quickly strobing from a laser light source. This light travels to the ground and reflects off of things like buildings and tree branches. The reflected light energy then returns to the LiDAR sensor where it is recorded. More > -

What is Lidar Data?
Lidar (light detection and ranging) is an optical remote-sensing technique that uses laser light to densely sample the surface of the earth, producing highly accurate x,y,z measurements. Lidar, primarily used in airborne laser mapping applications, is emerging as a cost-effective alternative to traditional surveying techniques such as photogrammetry. More >
