Advances in Forest Inventory Using Airborne Laser Scanning
We present two improvements for laser-based forest inventory. The first improvement is based on using last pulse data for tree detection. When trees overlap, the surface model between the trees corresponding to the first pulse stays high, whereas the corresponding model from the last pulse results in a drop in elevation, due to its better penetration between the trees. This drop in elevation ca...
متن کاملSimulating Sampling Efficiency in Airborne Laser Scanning Based Forest Inventory
A simple simulator was developed to test whether airborne laser scanning can be used as a strip sampling tool for forest inventory purposes. The simulator is based on the existing two stages, grid based laser inventory procedure. A population of trees was created using an existing forest stand structure generator. Each tree was represented by means of its 3D-crown model derived from airborne la...
متن کاملAirborne Laser Scanning – a New Challenge for Forest Inventory and Monitoring of Forest Resources
The use of the newest methods of airborne laser scanning integrated with hyper-spectral satellite systems, provides principally new opportunities for remote sensing of forest cover. High efficiency of laser scanning (up to 100 thousand measurements per second) in combination with sub-meter spatial resolution, high accuracy of a tree stands’ structural parameters detection as well as three-dimen...
متن کاملEstimation of Forest Variables using Airborne Laser Scanning
Holmgren, J. 2003. Estimation of Forest Variables using Airborne Laser Scanning. Doctoral dissertation. Airborne laser scanning can provide three-dimensional measurements of the forest canopy with high efficiency and precision. There are presently a large number of airborne laser scanning instruments in operation. The aims of the studies reported in this thesis were, to develop and validate met...
متن کاملForest Inventory and Biomass Assessment by the Use of Airborne Laser Scanning Method (example from Siberia)
The use of aerial laser scanning method provides a number of principally new possibilities on remote sensing of forest vegetation and specifically of a disturbed forest ecosystems (after wild fires, logging operations, insect outbreaks etc.) which area increases year by year in Siberia. The high efficiency of laser sensing survey (up to 50-70 thousand original measurements per second) combining...
