1. 1. Evaluating inventory methods for estimating stem diameter distributions in micro stands derived from airborn laser scanning

   University essay from SLU/Dept. of Forest Resource Management

   Author : Anders Lundholm; [2014]
   Keywords : kMSN; imputation; transect inventory; guided sampling; ALS;

   Abstract : A lot of research has focused on which laser metrics and which k-Nearest Neighbour (kNN) distances give the most accurate estimations. Most studies suggest that the kNN distance k-Most Similar Neighbour (kMSN) is the most accurate for estimating forest variables from local training data. READ MORE

3. 2. Tree Detection and Species Identification using LiDAR Data

   University essay from KTH/Geodesi och geoinformatik

   Author : Mohammad Amin Alizadeh Khameneh; [2013]
   Keywords : Airborn laser scanning; point cloud classification; tree detection; tree identification;

   Abstract : The importance of single-tree-based information for forest management and related industries in countries like Sweden, which is covered in approximately 65% by forest, is the motivation for developing algorithms for tree detection and species identification in this study. Most of the previous studies in this field are carried out based on aerial and spectral images and less attention has been paid on detecting trees and identifying their species using laser points and clustering methods.
