Assessing the Three-dimensional Frequency Distribution of Airborne and Ground-based Lidar Data for Red Pine and Mixed Deciduous Forest Plots

The following study reports on the preliminary results of a novel processing technique for characterizing the three-dimensional distribution of airborne and ground-based LiDAR data for conifer and mixed deciduous forest plots. The frequency of laser returns within 1m x 1m x 1m cubes (voxels) and the plotting of percentile distributions within each column (e.g. 1m x 1m x 25m, x, y, z) may benefi...

Enhanced Detection of 3d Individual Trees in Forested Areas Using Airborne Full-waveform Lidar Data by Combining Normalized Cuts with Spatial Density Clustering

A detailed understanding of the spatial distribution of forest understory is important but difficult. LiDAR remote sensing has been developing as a promising additional instrument to the conventional field work towards automated forest inventory. Unfortunately, understory (up to 50% of the top-tree height) in mixed and multilayered forests is often ignored due to a difficult observation scenari...

Litemapper-5600 – a Waveform-digitizing Lidar Terrain and Vegetation Mapping System

LiteMapper-5600 is a new high-accuracy airborne LIDAR system for corridor and wide-area mapping of terrain and vegetation with a unique feature: it digitizes the echo waveform of each measurement. This paper outlines the system and its components, presents first samples of data that were collected recently with a prototype in flight tests, and analyzes system performance. It highlights applicat...

Light Detection and Ranging-Based Terrain Navigation – A Concept Exploration

This paper discusses the use of Airborne Light Detection And Ranging (LiDAR) equipment for terrain navigation. Airborne LiDAR is a relatively new technology used primarily by the geo-spatial mapping community to produce highly accurate and dense terrain elevation maps. In this paper, the term LiDAR refers to a scanning laser ranger rigidly mounted to an aircraft, as opposed to an integrated sen...

Use of airborne lidar data to improve plant species richness and diversity monitoring in lowland and mountain forests

We explored the potential of airborne laser scanner (ALS) data to improve Bayesian models linking biodiversity indicators of the understory vegetation to environmental factors. Biodiversity was studied at plot level and models were built to investigate species abundance for the most abundant plants found on each study site, and for ecological group richness based on light preference. The usual ...
