What is LiDAR?

What is LiDAR? LiDAR (Light Detection and Ranging or Laser Imaging Detection and Ranging) is an optical remote sensing technology capable of measuring the distance to and properties of targets by illuminating them with laser light and analyzing the backscattered light. LiDAR uses a rapidly pulsed laser rangefinder mounted in light aircraft or ground based […]

Digitization from LiDAR (DTM, DEM and DSM)

Digitization from LiDAR (DTM, DEM and DSM) 1. Digital Terrain Model (DTM) The product DTM-design concerns the creation of a Digital Terrain Model for the purpose of road designs. In the DTM, the shape of a terrain is described with break lines. These break lines are captured in the desired coordinate system with the help […]

Pre-processing of LiDAR and Panoramic images

Pre-processing of LiDAR and Panoramic images

Pre-processing of LiDAR and Panoramic images LiDAR pre-processing In LiDAR pre-processing we fix systematic orientation errors in airborne and mobile laser data. It measures the differences between laser surfaces from overlapping strips of points or differences between laser surfaces and known points. These observed differences are translated into Heading (H), Roll (R) and Pitch (P) […]
