<ja:p>At the international level, various definitions have been established for compilation and publication of forest resources assessment results over last decade. These frequently rely on terms that are not precisely specified inventory purposes do completely cover requirements arising from application National Forest Inventory (NFI) data. Also, with respect to conventional topics such as area growing stock estimation, several expressions referring individual trees not, or only vaguely,...
Airborne laser scanning (ALS) is an active remote sensing technique that uses the time-of-flight measurement principle to capture three-dimensional structure of earth’s surface with pulsed lasers transmit nanosecond-long pulses a high pulse repetition frequency. Over forested areas most are reflected by leaves and branches trees, but certain fraction reaches forest floor through small gaps in canopy. Thus it possible reconstruct both canopy terrain surface. For retrieval quantitative...
National forest inventories typically estimate individual tree volumes using models that rely on measurements of predictor variables such as height and diameter, both which are subject to measurement error. The aim this study was quantify the impacts these errors uncertainty model-based stem volume estimates. were investigated two approaches: law propagation error Monte Carlo simulation. Estimates total also included variability associated with model itself. Results for approaches indicate...
The delineation of forested areas is a critical task, because the resulting maps are fundamental input for broad field applications and users. Different national international forest definitions available manual or automatic delineation, but unfortunately most lack precise geometrical descriptions different criteria. A mandatory criterion in crown coverage (CC), which defines proportion floor covered by vertical projection tree crowns. For loosely stocked areas, this especially critical,...
Anthropogenic GHG emissions add a fast reinforcing feedback cycle to global carbon dynamics which continues influence concentrations in the Earth's atmosphere. When looking at forest cycles there is potential utilizing another cycle, namely involving harvested wood products. To assess of mitigation options arising from these flows, forest-based sector Austria was modelled causal links, dependencies and involved GHG-relevant processes. Carbon were investigated forests soil carbon, product...
<ja:p>International agreements such as the Kyoto protocol and Convention on Biological Diversity (1992), well as, criteria indicator processes require reports status of nationsâ forests. Any comparison current trends forest resources among nations presumes that applied definitions concepts produce comparable estimates In spite this, FAO has already collected global information for 60 years made noticeable efforts in creating common definitions, but related data are still using diverse even...
The overall goal of this study was to describe a novel area-based semiempirical model for estimating growing stock from small-footprint light detection and ranging (lidar) data. assumes linear relationship between lidar-derived canopy volume that is stratified according several height classes account dependent differences in structure nonlinear tree size-shape relationships. It applied over 128 km 2 alpine area Austria where operational forest inventory data lidar acquired winter summer were...
Abstract National forest inventories are a primary source of data for national and large area assessments sustainability biodiversity international resource reporting. However, the ability countries to produce compatible estimates using these is impeded by diversity their inventory definitions, sampling designs, plot configurations, measured variables, measurement protocols. In addition, because differing features have historical, commercial, environmental justification, prospects...
This paper evaluates the performance of a recently developed approach for wide-area stem volume estimations based on airborne laser scanning (ALS) and national forest inventory (NFI) data in case where recorded under operational conditions are used as input. entails that neither ALS nor NFI samples were collected optimized current study. The was tested Austrian state Vorarlberg, which covers an area 2601 km2 encloses about 970 land. with point densities varying between 1 4 points m−2...
Harmonization is the process of making information and estimates comparable across administrative borders. The degree to which harmonization succeeds depends on many factors, including conciseness definitions, availability quality data, methods used convert an estimate according a local definition reference definition. requires use common definitions for converting from based national definitions. This article focuses conversion methods, are characterized as "bridges" because they can be...
The lack of consistent and accessible forest data in Europe still provides a challenge for large-scale assessments simulation studies. Here we compare two approaches providing detailed description the current state complex mountainous landscape Austria. Approach A integrates point-based National inventory with climate remote sensing to produce gridded information (forest type structural attributes) at 1 x km resolution. In addition these sets, approach B high resolution (10 m) tree species...
Consistent knowledge about the increment in European forests gained amplified importance policies and decision processes related to forest-based bioeconomy, carbon sequestration, sustainable forest management environmental changes. Until now, large-area information from countries was lacking international comparability. In this study we present a harmonisation framework accordance with principles approach established for of National Forest Inventories (NFIs) Europe. 11 NFIs, representing...
International agreements increasingly require that countries report estimates of national forest resources. The United Nations Framework Convention on Climate Change requires submit annual reports greenhouse gas emissions and removals by sources sinks. Biological Diversity identify monitor components biological diversity for purposes conservation sustainable use.
A pan-European effort to harmonize national forest inventories (NFI) was initiated under COST Action E43, "Harmonisation of National Forest Inventories in Europe: Techniques for Common Reporting." More than 30 countries and institutions, mainly from Europe, multiple international institutions joined the Action, which 2004. The main objective improve existing European NFIs by harmonizing information through development agreement on common inventory definitions. Other objectives were support...
Abstract • Key message A dataset of forest resource projections in 23 European countries to 2040 has been prepared for forest-related policy analysis and decision-making. Due applying harmonised definitions, while maintaining country-specific forestry practices, the should be usable from national international levels. The can accessed at https://doi.org/10.5061/dryad.4t880qh . associated metadata are available...
Airborne laser scanning (ALS) data can be used for downscaling point-based forest inventory (FI) measurements to obtain spatially distributed estimates of parameters at a more detailed, local scale. Such algorithms usually consist direct coupling between selected FI and ALS collected the field sampling locations. Thus, precise co-registration is an essential preprocessing step accurate predictive relationships. This paper presents new, automated approach that searches iteratively best match...
