متن کاملEvaluation and Future Prospects of Terrestrial Laser Scanning for Standardized Forest Inventories
Based on experiences from the NATSCAN-project this contribution focuses on the evaluation of two hypotheses: (i) Terrestrial laser scanning and corresponding data analysis is ready to be used in standardized forest inventory sampling. (ii) Data quality as well as characteristics related to the technique of laser scanning widen the data base for forest management applications and ecological inve...
متن کاملDescribing 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...
