Airborne Laser Measurement Technology in Japan

Kinematics GPS and inertia movement instrumentation technology has developed rapidly, which achieved to provide a high and stable accuracy of spatial positioning, attitude in three dimensions for high-speed movement platform such as aircraft. The airborne laser measurement system which is based on the laser scanning technology, has been integrated to the GPS inertia movement instrument on the a...

Airborne Laser Survey Systems: Technology and Applications

As mapping products become increasingly digital and require rapid updating, it is necessary for survey companies to use fast and cost-effective technologies. Airborne laser mapping provides a new alternative for traditional photogrammetric mapping. Based on a scanning laser and GPS/Inertial positioning system, an airborne laser system automatically produces accurate digital elevation models (DE...

Gaussian Half-Wavelength Progressive Decomposition Method for Waveform Processing of Airborne Laser Bathymetry

In an airborne laser bathymetry system, the full-waveform echo signal is usually recorded by discrete sampling. The accuracy of signal recognition and the amount of effective information that can be extracted by conventional methods are limited. To improve the validity and reliability of airborne laser bathymetry data and to extract more information to better understand the water reflection cha...

Application of Airborne Laser Technology to 3D Cadastre

SUMMARY Growing demand for an efficient land use above and below the ground is motivating cadastre and land management systems to move from traditional 2D systems toward three-dimensional ones. A major concern in realizing the 3D cadastre vision is the development of efficient methods for the attachment of the third dimension to the existing 2D systems. In this regard airborne laser technology ...
