ON THE USE OF AIRBORNE LASER SCANNING DATA TO VERIFY AND ENRICH ROAD NETWORK FEATURES
LIDAR Surface Parameter Extraction Detection
2015/8/13
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 POTENTIAL OF DISCRETE RETURN, SMALL FOOTPRINT AIRBORNE LASER SCANNING DATA FOR VEGETATION DENSITY ESTIMATION
laser scanning correlation point cloud forestry land cover
2015/8/13
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...
MEASURING THE GROWTH OF INDIVIDUAL TREES USING MULTI-TEMPORAL AIRBORNE LASER SCANNING POINT CLOUDS
Height growth laser scanning multi-temporal change detection
2015/8/13
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 ...
QUANTITATIVE MAPPING OF HYDRODYNAMIC VEGETATION DENSITY OF FLOODPLAIN FORESTS USING AIRBORNE LASER SCANNING
airborne laser scanning floodplains hydrodynamic vegetation density forest simulation
2015/8/13
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...
MAPPING LAND COVER IN THE TAITA HILLS, SE KENYA, USING AIRBORNE LASER SCANNING AND IMAGING SPECTROSCOPY DATA FUSION
GEOBIA LCCS Hyperspectral data
2015/5/7
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...
INVESTIGATING ADJUSTMENT OF AIRBORNE LASER SCANNING STRIPS WITHOUT USAGE OF GNSS/IMU TRAJECTORY DATA
Airborne Laser Scanning adjustment LIDAR georeferencing quality control
2016/2/29
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 ...
