Airborne laser scanning data as a source of field topographical characteristics
Plant, Soil and Environment, 2013 One of the factors frequently affecting yields is topography. Topographic data can be obtained from various sources with different precision. This work evaluates suitability of airborne laser scanning data for use as another source of topographical ...

Detecting overmature forests with airborne laser scanning (ALS)
Remote Sensing in Ecology and Conservation, 2022 Building a network of interconnected overmature forests is crucial for the conservation of biodiversity. Indeed, a multitude of plant and animal species depend on forest structural maturity attributes such as very large living trees and deadwood.

Automated Classification of Airborne Laser Scanning Point Clouds [PDF]
, 2014 Making sense of the physical world has always been at the core of mapping. Up until recently, this has always dependent on using the human eye. Using airborne lasers, it has become possible to quickly "see" more of the world in many more dimensions.

Transmittance of Airborne Laser Scanning Pulses for Boreal Forest Elevation Modeling
Remote Sensing, 2011 The transmittance of laser pulses through the forest canopy was studied as a function of forest attributes (inventory parameters) and the scanning angle from the point of view of elevation modeling.

Model-based inference for biomass estimation in a LiDAR sample survey in Hedmark County, Norway [PDF]
, 2011 In forest inventories, regression models are often applied to predict quantities such as biomass at the level of sampling units. In this paper, we propose a model-based inference framework for combining sampling and model errors in the variance ...
