%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% DESCRIPTION % These scripts calculate forest canopy structure metrics and density from high % resolution LiDAR point cloud data of forest canopy. % The scripts that estimate canopy structure metrics relates to research published as % % D. Moeser, F. Morsdorf, T. Jonas; Novel forest structure metrics % from airborne LiDAR data for improved snow interception estimation; % 2015; Agricultural and Forest Meteorology; % doi: 10.1016/j.agrformet.2015.04.013 % % Note: There are three versions of this script: % % Version 1.1 [Lidar2CanopyMetrics] % creates a binarized canopy height raster for each evaluation point separately. % % To the contrary, version 1.2 [Lidar2CanopyMetricsAlt] % creates a binarized canopy height raster encompassing the evaluation % domain for all evaluation points. As a consequence, version 1.2 is % quicker but requires more memory. Note however, that version 1.1 creates % a raster which is centered around the exact coordinate of an evalution point, % whereas version 1.2 uses % the nearest available raster cell. Therefor, paramter output from % both versions of the scripts is not identical, albeit very similar. % Version 2.0 [Lidar2CanopyMetricsGrid] % is derived from version 1.2 but gives a gridded output % instead of point output and allows the user to choose metric(s) of % interest. % % % Please look at sepcific README file for version of interest: % 1. README_Lidar2CanopyMetrics.txt % 2. README_Lidar2CanopyMetricsAlt.txt % 3. README_Lidar2CanopyMetricsGrid.txt % % These packages come with sample DTM and LiDAR data. % Note that the LIDAR folder is in .zip format due to size. % If using sample data please ensure folder is unzipped %% %% % The scripts that estimate canopy density metrics relates to research published as % % D.
