Available in PDF, EPUB and Kindle. Book excerpt: The past two decades have demonstrated a great potential for airborne Light Detection and Ranging (LiDAR) data to improve the efficiency of forest resource inventories (FRIs). In order to make efficient use of LiDAR data in FRIs, the data need to be related to observations taken in the field. Various modeling techniques are available that enable a data analyst to establish a link between the two data sources. While the choice for a modeling technique may have negligible effects on point estimates, different model techniques may deliver different estimates of precision. This study investigat...

Available in PDF, EPUB and Kindle. Book excerpt: How to manage forest resources and environment effectively? Remote sensing is a solution of invaluable support for this goal. The purpose and expectation of traditional forest inventory is to provide forest resource with reliable information. However, these inventories usually lack fine spatial resolution and even performed terrestrially only. In recent decades, the great progress in remote sensing and GIS has provided considerable opportunities for such forest inventories. Integrating these techniques and terrestrial data as an analysis of multi-source information is therefore of particular value. Estimation of forest structure e.g. stand volume using remote sensing has been broadly investigated both in study and in practice. However, most work was focused on the boreal or temperate forest. Relatively less attention has been devoted to moist tropical regions, and hardly has been made consideration of the forests in Vietnam. Hence, this book aims to share with you applicability of remote sensing in the tropical forest where the almost stand forests with complex structure and tree species diversity haven been degradated by human activities

Available in PDF, EPUB and Kindle. Book excerpt: This book has been developed as a forest inventory textbook for students and could also serve as a handbook for practical foresters. We have set out to keep the mathematics in the book at a fairly non-technical level, and therefore, although we deal with many issues that include highly sophisticated methodology, we try to present first and foremost the ideas behind them. For foresters who need more details, references are given to more advanced scientific papers and books in the fields of statistics and biometrics. Forest inventory books deal mostly with sampling and measurement issues, as found here in section I, but since forest inventories in many countries involve much more than this, we have also included material on forestry applications. Most applications nowadays involve remote sensing technology of some sort, so that section II deals mostly with the use of remote sensing material for this purpose. Section III deals with national inventories carried out in different parts of world, and section IV is an attempt to outline some future possibilities of forest inventory methodologies.

Book excerpt: Forest management is the management of private or public forest resources to achieve their conservation, social services, and economic values, concerned with the administrative, economic, legal and social aspects. All decision-making, operations-scheduling, and policy-planning require information of high quality. In forest management, this information is acquired by means of forest inventory: the systematic collection of data and information derived from forest measurements. A forest inventory is not only used for estimating the current growing stock, also conducted at several points of time in order to analyse temporal changes and yield forecasting. When conducting a forest inventory several forest parameters need to be taken into account, including individual tree heights, site quality, diameter at breast height, basal area, stocking, and timber volume. The main purpose of forest inventory is to measure these forest characteristics for estimating means and totals of timber products and planning harvest over a defined area (Kangas and Maltamo, 2006). However, it is infeasible to measure all individual trees (whole forest) in a large-scale region; therefore the acquisition of forest attributes is based on sampling. Typically, forest inventory is usually implemented by measuring the sample plots in the field, a proportion of the whole population of trees, to estimate the extent, quantity and condition of the whole forest. Thus, forest inventory in a large-scale plantation based on sampling involves time consuming and labour intensive field data collection. The development of remote sensing techniques makes it possible to conduct large-scale forest surveys with three-dimensional information at various scales from the forest stand level to individual tree level. Particularly, LiDAR (Light Detection and Ranging), an active remote sensing technique, emerges as rapid and efficient tool for forest inventories. It offers the ability to measure forest attributes at the individual tree level. This thesis aims to explore the potential of LiDAR data for automated forest inventory estimates. An integrated GIS tool was developed for constructing a forest inventory system for Pinus radiata plantations in Victoria, Australia. The tool was built as a set of tools running on the desktop GIS software package ArcGIS by integrating spatial analysis, LiDAR data analysis and image segmentation techniques as well as empirical tree models to support forest inventories of Pinus radiata on an individual tree basis. It provides functions for selecting forest plots to extract LiDAR data, building canopy height models (CHM) from the extracted LiDAR data, delineating individual trees on the CHMs by applying the marker controlled watershed segmentation technique, and deriving forest inventory estimates based on the CHMs and identified individual trees through spatial analysis and tree modelling using the empirical models. The integrated GIS tool was applied to a forest inventory of Pinus radiata plantations in Mt. Worth, Victoria, managed by HVP Pty Limited. The inventory results were validated using the field survey data. The tool not only provides a practical means of forest inventory of Pinus radiata plantations in southern Australia, but also a new approach to the development of a fully automated forest inventory system through the integration of advanced GIS and LiDAR technology.

Available in PDF, EPUB and Kindle. Book excerpt: Forest inventories throughout the world have evolved gradually over time. The content as well as the concepts and de?nitions employed are constantly adapted to the users’ needs. Advanced inventory systems have been established in many countries within Europe, as well as outside Europe, as a result of development work spanning several decades, in some cases more than 100 years. With continuously increasing international agreements and commitments, the need for information has also grown drastically, and reporting requests have become more frequent and the content of the reports wider. Some of the agreements made at the international level have direct impacts on national economies and international decisions, e. g. , the Kyoto Protocol. Thus it is of utmost importance that the forest information supplied is collected and analysed using sound scienti?c principles and that the information from different countries is comparable. European National Forest Inventory (NFI) teams gathered in Vienna in 2003 to discuss the new challenges and the measures needed to get data users to take full advantage of existing NFIs. As a result, the European National Forest Inventory Network (ENFIN), a network of NFIs, was established. The ENFIN members decided to apply for funding for meetings and collaborative activities. COST– European Cooperation in Science and Technology - provided the necessary ?n- cial means for the realization of the program.
