Vunathi provides a wide range of LiDAR data processing services that helps in creating Digital Elevation Models (DEM), Digital Terrain Models (DTM) and Triangulated Inverse Networks (TIN) to provide highly accurate detail of the Earth’s surface. LiDAR data processing services have helped global industries in taking informed decisions about their business. LiDAR data processing services enable the electrical utility industry with the efficient planning and maintenance of electric networks. LiDAR classification also gives a supporting hand to the agricultural sector, by watershed delineation and crop assessment mapping using LiDAR point cloud data. This way, LiDAR classification and LiDAR data processing assists many industrial sectors in planning and making informed decisions.
A LiDAR instrument principally consists of a laser, a scanner, and a specialized GPS receiver. Airplanes and helicopters are the most commonly used platforms for acquiring LiDAR data over broad areas. Two types of LiDAR are topographic and bathymetric. Topographic LiDAR typically uses a near-infrared laser to map the land, while bathymetric lidar uses water-penetrating green light to also measure seafloor and riverbed elevations. LiDAR systems allow scientists and mapping professionals to examine both natural and manmade environments with accuracy, precision, and flexibility. NOAA scientists are using LiDAR to produce more accurate shoreline maps, make digital elevation models for use in geographic information systems, to assist in emergency response operations, and in many other applications.
