For the past dozen years, data which enable the use of Digital Terrain Model as well as Digital Surface Model have been widely used. One of the modern techniques of gaining information about terrain i...
Density, diameter distribution and height-diameter (H-D) pattern of a forest stand are of primary importance in deriving various stand characteristics, but measuring diameters and heights of a tree st...
During last ten years the research concerning airborne laser scanning based forest inventory applications has been very active in different parts of the world. In Finland, both basic approaches, singl...
We have developed a new concept of empirical calibration scheme for airborne laser scanner (ALS) intensity by means of portablebrightness calibration targets, which can be laid out in the flight targe...
One of the most important aspects of documenting cultural heritage sites is acquiring detailed and accurate data. A popular method of storing 3D information about historical structures is using 3D mo...
This paper demonstrates the use of a matching algorithm to register an ALS data set to a reference surface composed of ground points obtained using kinematic stop-and-go GPS. The matching algorithm m...
Airborne Laser Scanning (ALS), Terrestrial Laser Scanning (TLS) and Vehicle based Laser Scanning (VLS) are widely used as data acquisition methods for 3D building modelling. ALS data is often used to ...
