50+Bathymetry Projects for Major Bridge Design
BPC offers a laser scanning solution for challenging topographic surveys to collect high-precision and high-accuracy data over large spatial extents.
3D laser scanning can be used efficiently for scanning proposed roads in hilly terrains which are normally inaccessible and can’t be surveyed with a total station due to high vegetation. As per project demand, we use 3D Laser scanner for constructing a digital three-dimensional model to provide the shape of 3D objects. Laser scanner use may be either active or passive scanners. Active scanners emit light, ultrasound or X-ray and detect its reflection or radiation while passive scanners detect reflected ambient radiation. Beside creating 3D modeling, the Laser scanner is also capable of topographic scanning, non- destructive testing of structures, and creating point cloud data of geometric surface.
LiDAR is an active optical remote sensing system emitting laser pulses, which are partially reflected by the ground. The distance between the sensor and the ground surface is measured by multiplying the velocity of the laser with the time elapsed between sending and receiving the laser pulse. LiDAR systems have the unique capability of measuring the three-dimensional structure of the Earth surface in great spatial detail. LiDAR mapping or '3D laser scanning' is basically a technology to make high-resolution maps, with applications in geodesy/geomatics, with terrestrial, airborne & mobile mapping methods.
