Build on soft soil, close to sea level the Netherlands is at high risk for the effects of subsidence and deformation. Interferometric Synthetic Aperture Radar (InSAR) is successfully used to monitor t...
Since the mid-1990s, the Institute of Photogrammetry and Remote Sensing (I.P.F.) is engaged in Airborne Laser Scanning (ALS) in research and development. Scientific contributions have been made...
High-resolution digital terrain models (DTM) provide accurate descriptions of our surrounding with respect to its 2.5D shape. Besides that existing cartographic databases provide detailed 2D represe...
The influence of low vegetation on laser scanning and its disturbing effect (a systematic positive height shift) during DTM generation is well recognized. Based on our experience in a previous study...
We evaluate the potential of deriving a vegetation leaf area index (LAI) from small footprint airborne laser scanning data. Based on findings from large area histograms of discrete laser return...
It is well known that characteristics of individual trees, such as tree height, biomass and crown area, can be derived from airborne laser scanning (ALS) and that heights for individual trees can be ...
In order to get an experimental insight on the characteristics of a modern airborne laser scanning system, we carry out a set of experiments using geometrical targets on an air strip and use differen...
The determination of hydrodynamic vegetation density of floodplain forests in the Netherlands is currently based on manually delineated vegetation types and a lookup table to convert these into vege...
At present, the calibration of airborne laser scanner data relies on the estimation of the position and attitude of the aircraft during the acquisition using GPS and INS systems, but also on the esti...
Whereas the objectives of a strip adjustment procedure are simple to define, namely improving the accuracy of laser data and creating a seamless dataset, achieving them is difficult. Compl...
The derived building models were evaluated for their correctness and geometric accuracy. Well-defined building roof planes can be extracted and reconstructed successfully, while disturbances such as...
Airborne laser scanner technique provides a 3D perception of the terrestrial topography, including true ground and objects belonging either to vegetated areas or to human made features. The high intr...
Airborne laser scanning, often referred to as lidar or laser altimetry, is a remote sensing technique which measures the round-trip time of emitted laser pulses to determine the topography of the Ea...
The Taita Hills, located in south-eastern Kenya, is one of the world’s biodiversity hotspots. Despite the recognized ecological importance of this region, the landscape has been heavily fragmented d...
Airborne laser scanning (ALS) requires GNSS (Global Navigation Satellite System; e.g. GPS) and an IMU (Inertial Measurement Unit) for determining the dynamically changing orientation of the scanning ...
