LiDAR Data Processing

LIDAR—Light Detection and Ranging, a remote sensing method is used to examine the surface of the Earth. It involves a scanning and ranging laser system that produces pinpoint accurate, high-resolution topographic maps. Today, the entire process of airborne laser mapping is highly automated, from flight planning, to data acquisition and the generation of digital terrain models.

The WET team is adept at understanding and utilizing new technologies, specifically LIDAR or Laser point processing and visualization software. Initial output is in generic ASCII X, Y, Z data format, in WGS84. This data is typically converted according to the clients’ needs with respect to datum and coordinate systems.

  • Generation of DTM / DSM and contours
  • Surface and land use classification, characterization
  • Generation of elevation profiles, Digital Surface Models (DSM) and Digital Terrain Models (DTM) as raster, TIN, contour or slope models.
  • Determination of height of forest canopy.
  • Mapping of urban areas with high-rise buildings.
  • Power line mapping.
  • 3-D town / city modeling.
  • Coastal Zone management.
  • Pipeline planning.
  • Integrated with Photogrammetric applications: Planimetric compilation, break line compilation, automatic contour generation, and Orthophoto and GIS visualization.
