What it is?

LiDAR  (Light Detection And Ranging) is a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light. The term LIDAR stands for Light Detection and Ranging. LiDAR is the Remote Sensing technology that can find the range and other information about a particular distant object by the means of measuring the properties of scattered lights. It 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

LiDAR Survey facilitates the acquisition of data of thousand points over the Earth's surface within a fraction of a second accurately. LiDAR is one of the most important breakthroughs in Optical Remote Sensing technologies. In LiDAR Survey, the data are collected from individual points over the ground surface.

The point data is post-processed after the lidar data collection survey into highly accurate georeferenced x,y,z coordinates by analyzing the laser time range, laser scan angle, GPS position, and INS information.

Post-processed spatially organized lidar data is known as point cloud data. The initial point clouds are large collections of 3D elevation points, which include x, y, and z, along with additional attributes such as GPS time stamps. The specific surface features that the laser encounters are classified after the initial lidar point cloud is post-processed. Elevations for the ground, buildings, forest canopy, highway overpasses, and anything else that the laser beam encounters during the survey constitutes point cloud data.

LiDAR mapping has many advantages over conventional surveying methods

•  It has the ability to penetrate tree canopy and vegetation even in densely covered areas
•  It has the flexibility to collect data round the year and even in night.
•  With this technique data can be collected rapidly
•  Data collected in this technique is of higher accuracy
•  LiDAR survey has reduced Cost
  

What we do?

Someshinfotech process the LiDAR point data to generate DEM ( Digital Elevation Model), TIN (Triangulated Inverse Network), DTM (Digital Terrain Model) and many other surface models.

Using different post processing tools we remove noise points, attribute points by layer, use automated filters to classify ground points. Manual classification is done for the remaining points which are not automatically classified. 

Final deliverables are produced for use in GIS applications. These products include digital elevation models (DEM), digital terrain models (DTM), digital surface models (DSM), Triangulated Irregular Networks (TIN), and contour maps. Supplemental break lines are often added to ensure realistic representation of distinctive terrain features.
