Lidar Technology
Lidar or Light detection and Ranging refers to optical remote sensing technology capable of measuring distances and other properties of any target. This technology illuminates a target with light often using laser pulses to measure details of a target. This system uses three technologies namely (a) Laser, (b) Satellite positioning using GPS and (c) Inertia Measure Unit (IMU) to record object orientation. For topography mapping exercises LiDar systems use infrared laser light which is safe for eyes. Its active sensing system uses own energy source instead of emitted radiation. LiDAR is often applied in geomatics, geography, archaeology, geology, forestry, remote sensing and atmospheric physics. LiDar technology’s advantages are higher or better resolution, accuracy to centimeter level and high degree of penetration in forest terrain.
Vegetation Mapping
LiDAR being an active sensor can be used day or night as long as atmosphere is clear. The two main categories of resource management applications which use LiDAr are a. Vegetation mapping and b) topography mapping. LiDAR vegetation mapping technique measures three dimensional characteristics of plant canopies to estimate vertical structure of vegetation areas. LiDar vegetation mapping technology is very advanced and uses complex three dimensional pattern of forest land structure to access forest canopy and capture details of ground and elevation of vegetation cover.
Applications of LiDar Technology
LiDAR Mapping companies use this technology to map features that lie below forest canopy, assisting in field campaigns, providing a broad picture of the features that cannot be viewed or distinguished on the ground. Location of archaeological sites of micro topography and identifying areas of fuel accumulation to reduce chances of forest fires are some regular solutions offered by Lidar mapping companies through interpretation and analysis of data. The three technologies of By mounting Lidar sensors on mobile navigation systems such as aircrafts, satellites etc can help as GPS (Global Positioning Systems) and Inertial Measurement Unit (IMU). Farmers have been greatly benefited by this technology, since it provides information about the areas where costly fertilizers need to be applied.
Some Companies, a United States based risk management services company, provides risk specific inventory and analysis by remote sensing technology to utility companies. In its vegetation management analysis uses LiDar (Light Detection and Ranging) to identify and map vegetation threats and predict infrastructure changes due to load, temperature and climatic factors.
