Download or read book Measurements and Estimations of Forest Stand Parameters Using Remote Sensing written by Donald A. Stellingwerf and published by VSP. This book was released on 1997-08 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Generally speaking, the use of remote sensing imagery will reduce field work. Remote sensing imagery gives an overall view of the forest in addition to more detailed information, the extent of which depends mainly on scale and film used in case of analogue data, and mainly on pixel size in case of digital data. This book deals with measurements and estimations of forest stand parameters using aerial photographic, aircraft and satellite scanning data, radar and laser imagery. It includes technical and statistical information of practical examples from both temperate and tropical forests. Statistical analysis of measurement data and sampling techniques are given when required. The obtained results are compared with those from other techniques, showing their relative advantage or disadvantage.

Book Synopsis Forest Mensuration by : John A. Kershaw, Jr.
Download or read book Forest Mensuration written by John A. Kershaw, Jr. and published by John Wiley & Sons. This book was released on 2016-12-27 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest mensuration – the science of measurement applied to forest vegetation and forest products – holds value for basic ecology as well as sustainable forest management. As demands on the world’s forests have grown, scientists and professionals are increasingly called on to quantify forest composition, structure, and the goods and services forests provide. Grounded in geometry, sampling theory, and ecology as well as practical field experience, forest mensuration offers opportunities for creative problem solving and critical thinking. This fifth edition of the classic volume, Forest Mensuration, includes coverage of traditional and emerging topics, with attention to SI and Imperial units throughout. The book has been reorganised from the fourth edition to better integrate non-timber and ecological aspects of forest mensuration at the tree, stand, forest, and landscape scales throughout. The new edition includes new chapters that specifically address the integration of remotely sensed data in the forest inventory process, and inventory methods for dead and downed wood. One unifying theme, not only for traditional forestry but for the non-timber inventory and for remote sensing, is the use of covariates to make sampling more efficient and spatially explicit. This is introduced in the introductory chapter on statistics and the chapter on sampling designs has been restructured to highlight this approach and lay the foundation for further learning. New examples will be developed throughout the textbook with an emphasis on current issues and international practice. Students in applied forestry programs will find ample coverage of forest products and timber inventory, while expanded material on biodiversity, biomass and carbon inventory, downed dead wood, and the growing role of remote sensing in forest assessment will be valuable to a broader audience in applied ecology.

Download or read book Forest Inventory written by Annika Kangas and published by Springer Science & Business Media. This book was released on 2006-02-19 with total page 368 pages. 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 Synopsis Quantifying Forest Structure Parameters and Their Changes from LiDAR Data and Satellite Imagery in the Sierra Nevada by : Qin Ma
Download or read book Quantifying Forest Structure Parameters and Their Changes from LiDAR Data and Satellite Imagery in the Sierra Nevada written by Qin Ma and published by . This book was released on 2018 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sierra Nevada forests have provided many economic benefits and ecological services to people in California, and the rest of the world. Dramatic changes are occurring in the forests due to climate warming and long-term fire suppression. Accurate mapping and monitoring are increasingly important to understand and manage the forests. Light Detection and Range (LiDAR), an active remote sensing technique, can penetrate the canopy and provide three-dimensional estimates of forest structures. LiDAR-based forest structural estimation has been demonstrated to be more efficient than field measurements and more accurate than those from passive remote sensing, like satellite imagery. Research in this dissertation aims at mapping and monitoring structural changes in Sierra Nevada forests by taking the advantages of LiDAR. We first evaluated LiDAR and fine resolution imagery-derived canopy cover estimates using different algorithms and data acquisition parameters. We suggested that LiDAR data obtained at 1 point/m2 with a scan angle smaller than 12°were sufficient for accurate canopy cover estimation in the Sierra Nevada mix-conifer forests. Fine resolution imagery is suitable for canopy cover estimation in forests with median density but may over or underestimate canopy cover in extremely coarse or dense forests. Then, a new LiDAR-based strategy was proposed to quantify tree growth and competition at individual tree and forest stand levels. Using this strategy, we illustrated how tree growth in two Sierra Nevada forests responded to tree competition, original tree sizes, forest density, and topography conditions; and identified that the tree volume growth was determined by the original tree sizes and competitions, but tree height and crown area growth were mostly influenced by water and space availability. Then, we calculated the forest biomass disturbance in a Sierra Nevada forest induced by fuel treatments using bi-temporal LiDAR data and field measurements. Using these results as references, we found that Landsat imagery-derived vegetation indices were suitable for quantifying canopy cover changes and biomass disturbances in forests with median density. Large uncertainties existed in applying the vegetation indices to quantify disturbance in extremely dense forests or forests only disturbed in the understory. Last, we assessed vegetation losses caused by the American Fire in 2013 using a new LiDAR point based method. This method was able to quantify fire-induced forest structure changes in basal area and leaf area index with lower uncertainties, compared with traditional LiDAR metrics and satellite imagery-derived vegetation indices. The studies presented in this dissertation can provide guidance for forest management in the Sierra Nevada, and potentially serve as useful tools for forest structural change monitoring in the rest of the world.

Book Synopsis The Use of Remote Sensing in the Modeling of Forest Productivity by : H.L. Gholz
Download or read book The Use of Remote Sensing in the Modeling of Forest Productivity written by H.L. Gholz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests comprise the greatest storage of carbon on land, provide fuel for millions, are the habitat for most terrestrial biodiversity, and are critical to the economies of many countries. Yet changes in the extent and dynamics of forests are inherently difficult to detect and quantify. Remote sensing technologies may facilitate the measurement of some key forest properties which, when combined with other information contained in various computer models, may allow for the quantification of critical forest functions. This book explores how remote sensing and computer modeling can be combined to estimate changes in the carbon storage, or productivity, of forests - from the level of the leaf to the level of the globe. Land managers, researchers, policy makers and students will all find stimulating discussions among an international set of experts at the cutting edge of the interface between science, technology and management.

Book Synopsis Modeling Forest Stands Structures and Biomass Quantification by : Khongor Tsogt
Download or read book Modeling Forest Stands Structures and Biomass Quantification written by Khongor Tsogt and published by LAP Lambert Academic Publishing. This book was released on 2014-09-02 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapters 1 and 2 represent simple distribution modeling while Chapters 3 and 4 compares the results of simple and mixture distribution modeling. Chapter 1 shows suitable distribution model selection for forest diameter structure modeling in case of a pure larch forest stand. Chapter 2 shows also distribution model selection, but for both diameter and height structures in case of pure pine forest stands. Rather than distribution model selection, Chapter 3 shows a comparison of simple and mixture distribution modeling in structural parameters, both diameter and height in case of spruce-larch mixed forest. Chapter 4 shows flexible mixture distribution modeling in case of larch forest stands and further diameter-height relationships discovered for volume estimation. In chapter 5, we are concentrated on one of the important tasks of quantifying forests AGB. In chapter 6, we developed regression models for AGB and its surrogate of ground measured LAI by using their relationship with satellite image based vegetation indices (VI). Quantification of AGB and LAI on regional scale, accurate forest type map needed. For that, in chapter 7 we studied forest type mapping.

Book Synopsis A System for Estimating Water Content of Conifer Forests Using Hyperspectral Remote Sensing Data by : Jing Yang Li
Download or read book A System for Estimating Water Content of Conifer Forests Using Hyperspectral Remote Sensing Data written by Jing Yang Li and published by . This book was released on 2006 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimation of foliage water content from remote sensing data is critical to wildfire management and monitoring forest health. Several efforts to estimate vegetation water content have relied on empirical relationships and data-specific calibrations. Therefore, the approaches used by these studies are not applicable to larger scales and different species. This work was undertaken to develop systems for retrieving foliage water content of Douglas-fir stands with closed canopy. The canopy structural parameters were constrained by forest dynamic relationships. Sensitivity analysis was used to quantify the influence of foliage water content and other factors (LAI, canopy closure, soil) on canopy reflectance simulated in the spectral range between 400 and 2400 nm. Lookup tables were generated using a forest radiative transfer model. Fuel moisture content (FMC) of Douglas-fir can then be determined from airborne hyperspectral imagery (AVIRIS) by the lookup table method. We achieved an accuracy of R2 of 0.74 for FMC which was assessed through comparisons of the estimated foliage water content with field measurements. A software system. FMAS (Fuel Moisture Content Mapping System), was developed for the estimation of fuel moisture content of Douglas-fir forests. Conclusions and further research issues were discussed.
