In this study, multispectral Light Detection and Ranging (LiDAR) data were utilized to improve delineation of individual tree crowns (ITC) as an important step in individual tree analysis. A framework to integrate spectral and height information for ITC delineation was proposed, and the multi-scale algorithm for treetop detection developed in one of our previous studies was improved. In addition, an advanced region-based segmentation method that used detected treetops as seeds was proposed for segmentation of individual crowns based on their spectral, contextual, and height information.

Relationship Between Image Spectroscopy Spatial Resolution And Crown Level Tree Species Classification Accuracy written by and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2021 with Hyperspectral imaging categories.
Hyperspectral imagery has become a common remote sensing data type used in tree species classifications because of its rich spectral signals that allow the detection of the variations in canopy reflectance. While high spatial resolution hyperspectral imagery provides fine spatial resolution for discerning surface objects, it has the inherent drawbacks of expensive acquisition costs, large data sizes, and can be computationally taxing to use. This study attempts to determine a relationship between crown level tree species classification accuracy and hyperspectral spatial resolution. Future tree species classification projects can make use of this relationship by targeting a spatial resolution that best avoids the drawbacks of hyperspectral imagery. I processed a 37-band hyperspectral mosaic that has a 0.3 meters resolution and resampled it to 0.5, 1.0, 2.0, 3.0, and 5.0 meters mosaics and used a support vector machine (SVM) classifier to create tree species classifications for each of the resampled mosaics to examine the relationship between spatial resolution and classification accuracies. The mosaic covers a 50 sq-km study site in El Dorado County, California. The classifier used tree species data that I collected in the field as training and validation data. The results show that there was no significant classification accuracy difference between the resolutions. The averaged overall accuracies were highest when using the 1.0 meters mosaic (73.23%) and dropped when increasing or decreasing the spatial resolutions. The 5.0 meters mosaic yielded a minimum overall accuracy of 64.42%. The finding suggests that spatial resolution is not a critical factor in classification accuracy, indicating that reasonable classification results can be achieved using either coarser resolution imagery, such as those collected with satellite or airborne sensors, or fine resolution imagery, such as those collected with unmanned aerial vehicles (UAV). The crown size of the trees appears to be an important factor mediating classification accuracy and image resolution. The knowledge gained in this study could help remote sensing project managers to determine a resolution that best fits their budget and computational power.

Airborne laser scanning (ALS) has emerged as one of the most promising remote sensing technologies to provide data for research and operational applications in a wide range of disciplines related to management of forest ecosystems. This book provides a comprehensive, state-of-the-art review of the research and application of ALS in a broad range of forest-related disciplines, especially forest inventory and forest ecology. However, this book is more than just a collection of individual contributions – it consists of a well-composed blend of chapters dealing with fundamental methodological issues and contributions reviewing and illustrating the use of ALS within various domains of application. The reviews provide a comprehensive and unique overview of recent research and applications that researchers, students and practitioners in forest remote sensing and forest ecosystem assessment should consider as a useful reference text.

Many terms often used to describe old-growth forests imply that these forests are less vigorous, less productive and less stable than younger forests. But research in the last two decades has yielded results that challenge the view of old-growth forests being in decline. Given the importance of forests in battling climate change and the fact that old-growth forests are shrinking at a rate of 0.5% per year, these new results have come not a moment too soon. This book is the first ever to focus on the ecosystem functioning of old-growth forests. It is an exhaustive compendium of information that contains original work conducted by the authors. In addition, it is truly global in scope as it studies boreal forests in Canada, temperate old-growth forests in Europe and the Americas, and global tropical forests. Written in part to affect future policy, this eminently readable book is as useful for the scientist and student as it is for the politician and politically-interested layman.
