Describing Forest Stands Using Terrestrial Laser-scanning
A method for extracting forest parameters is described in this paper. The 3D point clouds derived from phase difference laser scanners in forests were processed in a step-wise separation. The first step contains basic filter methods to reduce raw data which, separates isolated points or deletes those artefacts resulting from the ambiguity problem. The next step includes using algorithms to isol...

متن کاملThree-dimensional forest canopy structure from terrestrial laser scanning
A terrestrial laser scanner was used to measure the three-dimensional structure of forest stands in the Swiss National Park, eastern Switzerland. Spatially coincident hemispherical photographs were taken at each sampling point and the position of each point was determined using differential GPS. A scanner model was derived in order to determine the expected number of laser shots in all directio...
متن کاملTerrestrial Laser Scanning for Plot-Scale Forest Measurement
Plot-scale measurements have been the foundation for forest surveys and reporting for over 200 years. Through recent integration with airborne and satellite remote sensing, manual measurements of vegetation structure at the plot scale are now the basis for landscape, continental and international mapping of our forest resources. The use of terrestrial laser scanning (TLS) for plot-scale measure...
متن کاملTwo-dimensional Forest Canopy Architecture from Terrestrial Laser Scanning
Terrestrial laser scanners (TLS) are now capable of collecting 3d data clouds consisting of the x,y,z coordinates of several million laser hits, plus information on return intensity and, in some cases, target colour. TLS collect data at sub-centimetre resolution at a range of zenith view angles. This paper describes the results of a series of experiments in which a TLS was used to measure the t...
