Innovation in forest inventory, data transparency and software management are bringing the opportunity to make a significant decision-making and additional information for the forestry sector. During the last years, airborne laser scanning has been utilized in Finlandu2019s forest inventory. The detailed information can be utilized for the Internet based applications, like the forest management and further wood trading services. The aim of the study was to innovate the open source forest airborne laser scanning data for forest management and wood trading services. The data of forest biomass was based on the latest laser scanning from the final cutting proposals at the regional area of Finland. The laser scanning results indicated the volume of roundwood and the forest energy potentials from stumps and logging residues. However, some restrictions must be done when analysing the regional forest biomass potentials. For example, non-industrial private forest ownersu00b4 willingness to sell forest biomass for energy purposes has significant role for availability of biomass. The study showed a huge regional potential of forest biomass according to the final cutting proposals. However, realistic and sustainable forest biomass potential must be carefully done by combining several study information. By using airborne laser scanning method, the forest resources can be evaluated more effectively and could be used more sustainable at the regional level. It also enables to develop the new solutions for the digital forest management and wood trading services.

Book Synopsis Estimating Forest Structural Characteristics with Airborne Lidar Scanning and a Near-real Time Profiling Laser Systems by : Kaiguang Zhao
Download or read book Estimating Forest Structural Characteristics with Airborne Lidar Scanning and a Near-real Time Profiling Laser Systems written by Kaiguang Zhao and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: LiDAR (Light Detection and Ranging) directly measures canopy vertical structures, and provides an effective remote sensing solution to accurate and spatiallyexplicit mapping of forest characteristics, such as canopy height and Leaf Area Index. However, many factors, such as large data volume and high costs for data acquisition, precludes the operational and practical use of most currently available LiDARs for frequent and large-scale mapping. At the same time, a growing need is arising for realtime remote sensing platforms, e.g., to provide timely information for urgent applications. This study aims to develop an airborne profiling LiDAR system, featured with on-the-fly data processing, for near real- or real- time forest inventory. The development of such a system involves implementing the on-board data processing and analysis as well as building useful regression-based models to relate LiDAR measurements with forest biophysical parameters. This work established a paradigm for an on-the-fly airborne profiling LiDAR system to inventory regional forest resources in real- or near real- time. The system was developed based on an existing portable airborne laser system (PALS) that has been previously assembled at NASA by Dr. Ross Nelson. Key issues in automating PALS as an on-the-fly system were addressed, including the design of an archetype for the system workflow, the development of efficient and robust algorithms for automatic data processing and analysis, the development of effective regression models to predict forest biophysical parameters from LiDAR measurements, and the implementation of an integrated software package to incorporate all the above development. This work exploited the untouched potential of airborne laser profilers for realtime forest inventory, and therefore, documented an initial step toward developing airborne-laser-based, on-the-fly, real-time, forest inventory systems. Results from this work demonstrated the utility and effectiveness of airborne scanning or profiling laser systems for remotely measuring various forest structural attributes at a range of scales, i.e., from individual tree, plot, stand and up to regional levels. The system not only provides a regional assessment tool, one that can be used to repeatedly, remotely measure hundreds or thousands of square kilometers with little/no analyst interaction or interpretation, but also serves as a paradigm for future efforts in building more advanced airborne laser systems such as real-time laser scanners.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than a century, forest inventories have been used to support forest management and timber valuation activities. Today's inventories still rely primarily on manual measurements combined with sampling and modeling techniques. In recent years, new opportunities in carbon sequestration and an increasingly sophisticated timber market have prompted a need for more scalable and efficient inventory methods. To meet this demand, the industry has turned to remote sensing--predominantly light detection and ranging (LiDAR), which utilizes lasers to scan and measure features in 3D space. While much progress has been made, data resolution and cost challenges for both airborne and terrestrial LiDAR still exist. Airborne Laser Scanning (ALS) is more efficient for measuring large forest areas but faces challenges with respect to resolution and occlusion, leading to omission of understory trees. Terrestrial Laser Scanning (TLS) performs better in those respects but relies on expensive and typically unwieldy hardware. Area-based LiDAR approaches have been successful for large-scale applications but are not ideal for smaller parcels. As such, a need persists for a LiDAR-based solution that enables efficient generation of large-area forest inventory data yet is scalable to smaller forest plots and a range of forest types. The objective of this study was the development of a scalable individual tree detection method that leveraged airborne LiDAR data and performed well in mixed-species hardwood forests found in the northeastern United States. Existing research in individual tree detection has focused on methods that work well in conifer-dominated forests and homogenous settings such as plantations. These approaches, many of them based on top-down canopy height models, perform less favorably in deciduous stands due to the canopy complexity and crown characteristics inherent to these forest types. The voxel-based method proposed here uses detailed ground-measured tree survey data and leaf-off LiDAR collected in 2019-2020 over the Shavers Creek Watershed in Pennsylvania, United States. The method detected 68% of all reference trees greater than 10cm diameter at breast height (DBH) and 87% of sawtimber-sized trees greater than 28cm DBH, and it performed consistently across 48 subplots in the three-hectare test area. A new tree matching method leveraging linear integer programming was used for training and evaluation of the method. This tool enabled true one-to-one matching of predicted and reference trees and the validation of tree detections. Mean positional accuracy for predicted trees was within one meter of ground-measured reference trees. The results indicate the method has potential to be operationalized for both traditional forest management activities and in meeting the demand for more frequent and scalable inventories spurred by a growing forest carbon sequestration industry.
Book Synopsis Mapping Individual Trees with Airborne Laser Scanning Data in an European Lowland Forest Using a Self-calibration Algorithm by : Krzysztof Sterenczak

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Traditional field-based forest inventories tend to be expensive, time-consuming, and cover only a limited area of a forested region. Remote sensing (RS), especially airborne laser scanning (ALS) has opened new possibilities for operational forest inventories, particularly at the single-tree level, and in the prediction of single-tree characteristics. Throughout the world, forests have varying characteristics that necessitate the development of modern, effective, and versatile tools for ALS data processing. To address this need, we aimed to develop a tool for individual tree detection (ITD) utilising a self-calibrating algorithm procedure and to verify its accuracy using the complicated forest structure of near natural forests in the temperate zone. This study was carried out in the Polish part of the Białowieża Forest (BF). The airborne laser scanner (ALS) and color-infrared (CIR) datasets were acquired for more than 60 000 ha. Field-based measurements were performed to provide reference data at the single tree level. We introduced a novel ITD method that is self-calibrated and uses a hierarchical analyses of the canopy height model. There were more than 20 000 000 of trees in first layer in BF above 7 m height. Trees visible from above were divided into coniferous, deciduous and mixed trees that were then matched with an accuracy of 85 %, 85 % and 75 %, respectively. Compared to existing methods, the proposed method is more flexible and achieves better results, especially for deciduous species. Before application of the presented method to other regions, the calibration based on the developed optimisation procedure is needed

Book Synopsis Forecasting Forest Inventory for Spruce Plantations Using Airborne Laser Scanning Data by : Sean Lamb
Download or read book Forecasting Forest Inventory for Spruce Plantations Using Airborne Laser Scanning Data written by Sean Lamb and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the imputation of tree-level inventory for light detection and ranging (LiDAR) grid cells across 83 000 ha of spruce (Picea sp.) plantations to permit forecasting forest inventory using a tree-list growth model. Grid cells with LiDAR-derived inventory predictions were matched with one of over 5500 spruce plantation sample plot measurements based on planted species and minimum sum of squared difference between total and merchantable basal area, total and merchantable volume, top height, and merchantable quadratic mean diameter. Imputed tree lists resulted in inventory variable values that were highly correlated with observed values and statistically equivalent basal area distributions. When input into a locally calibrated tree-list growth model, variable increments predicted using imputed tree lists were strongly correlated with those using measured tree lists, resulting in predicted volumes that were similar to observed volumes. Using forecasted inventory variables, annual commercial thinning treatments were planned at grid-cell resolution from 2018–2020.
