Book Synopsis Vertical Structure and Aboveground Biomass of Tropical Forests from Lidar Remote Sensing by : Fabio Guimarães Gonçalves
Download or read book Vertical Structure and Aboveground Biomass of Tropical Forests from Lidar Remote Sensing written by Fabio Guimarães Gonçalves and published by . This book was released on 2015 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods for obtaining accurate, spatially explicit estimates of biomass density in tropical forests are required to reduce uncertainties in the global carbon cycle, and to support international climate agreements and emerging carbon markets. Three-dimensional (3-D) remote sensing techniques sensitive to the vertical structure of vegetation provide a unique opportunity for mapping and monitoring forest carbon stocks across large areas in the tropics. However, approaches to forest biomass estimation from remotely sensed structure have yet to be fully developed to deliver the required biomass accuracy. In this research, we use airborne laser scanning (ALS), space-based lidar observations (ICESat/GLAS), and detailed in situ measurements made at the Tapajós National Forest, Brazil, to advance methods of biomass estimation in tropical regions from remotely sensed structure. The overall objectives were to (1) test and refine methods for the extraction of structural information from lidar data; (2) determine the accuracy of lidar estimates of structure in relation to detailed field measurements of vertical structure; and (3) develop and validate structure-based models for optimal prediction of aboveground biomass. Because remote sensing approaches to biomass estimation begin with field estimates of biomass, field plot data collected at Tapajós were also used to gain a better understanding of the uncertainty associated with plot-level biomass estimates obtained specifically for calibration of remote sensing data. This included an evaluation of the error resulting from spatial disagreement between field and remote sensing measurements (i.e., co-location error), and the error introduced when accounting for temporal differences in data acquisition. Results show that a new approach to biomass estimation based on Fourier transforms of lidar profiles significantly improves predictions of aboveground biomass ranging from 2 to 538 Mg ha−1 in primary and secondary forests. Data from two different regions in the Amazon were used to demonstrate and test this method in a range of conditions. The improvement in biomass estimation performance was consistent across sites and the approach was integrated in a multi-stage scaling strategy to biomass estimation to produce a wall-to-wall map of biomass across a large area in the Amazon.
Book Synopsis Remote Sensing of Above Ground Biomass by : Lalit Kumar
Download or read book Remote Sensing of Above Ground Biomass written by Lalit Kumar and published by MDPI. This book was released on 2019-08-20 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Above ground biomass has been listed by the Intergovernmental Panel on Climate Change as one of the five most prominent, visible, and dynamic terrestrial carbon pools. The increased awareness of the impacts of climate change has seen a burgeoning need to consistently assess carbon stocks to combat carbon sequestration. An accurate estimation of carbon stocks and an understanding of the carbon sources and sinks can aid the improvement and accuracy of carbon flux models, an important pre-requisite of climate change impact projections. Based on 15 research topics, this book demonstrates the role of remote sensing in quantifying above ground biomass (forest, grass, woodlands) across varying spatial and temporal scales. The innovative application areas of the book include algorithm development and implementation, accuracy assessment, scaling issues (local–regional–global biomass mapping), and the integration of microwaves (i.e. LiDAR), along with optical sensors, forest biomass mapping, rangeland productivity and abundance (grass biomass, density, cover), bush encroachment biomass, and seasonal and long-term biomass monitoring.

Book Synopsis Remote Sensing of Leaf Area Index (LAI) and Other Vegetation Parameters by : Francisco Javier García-Haro
Download or read book Remote Sensing of Leaf Area Index (LAI) and Other Vegetation Parameters written by Francisco Javier García-Haro and published by MDPI. This book was released on 2019-09-16 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring of vegetation structure and functioning is critical to modeling terrestrial ecosystems and energy cycles. In particular, leaf area index (LAI) is an important structural property of vegetation used in many land surface vegetation, climate, and crop production models. Canopy structure (LAI, fCover, plant height, and biomass) and biochemical parameters (leaf pigmentation and water content) directly influence the radiative transfer process of sunlight in vegetation, determining the amount of radiation measured by passive sensors in the visible and infrared portions of the electromagnetic spectrum. Optical remote sensing (RS) methods build relationships exploiting in situ measurements and/or as outputs of physical canopy radiative transfer models. The increased availability of passive (radar and LiDAR) RS data has fostered their use in many applications for the analysis of land surface properties and processes, thanks also to their insensitivity to weather conditions and the capability to exploit rich structural and textural information. Data fusion and multi-sensor integration techniques are pressing topics to fully exploit the information conveyed by both optical and microwave bands.

Book Synopsis Vertical Decomposition of Forest Structure Using LiDAR Remote Sensing by : Hamish Asmath
Download or read book Vertical Decomposition of Forest Structure Using LiDAR Remote Sensing written by Hamish Asmath and published by . This book was released on 2006 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertical LiDAR profiles that measure the vertical organization of the canopy structure were created and used to classify the study area based upon reference profiles developed from selected silvicultural practices present in the Turkey Lakes Watershed. A previous method of estimating LAI from LiDAR data uses the vegetation returns to calculate the mean vegetation height. A new method of estimating LAI based upon the area under the vertical LiDAR profile was developed that is more accurate than the mean vegetation height approach. A procedure was developed to vertically distribute the LAI throughout the forest canopy using the estimated LAI and the LiDAR vertical profile. The result was a vertical LAI profile for each pixel. This allowed for the calculation of LAI at a specified height, and the height a specified LAI occurs. Vertical decomposition of LAI was performed at the plot level (20 x 20 m) and the canopy level (5 x 5 m).

Book Synopsis Polarimetric Synthetic Aperture Radar by : Irena Hajnsek
Download or read book Polarimetric Synthetic Aperture Radar written by Irena Hajnsek and published by Springer Nature. This book was released on 2021-03-24 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book focuses on the practical application of electromagnetic polarimetry principles in Earth remote sensing with an educational purpose. In the last decade, the operations from fully polarimetric synthetic aperture radar such as the Japanese ALOS/PalSAR, the Canadian Radarsat-2 and the German TerraSAR-X and their easy data access for scientific use have developed further the research and data applications at L,C and X band. As a consequence, the wider distribution of polarimetric data sets across the remote sensing community boosted activity and development in polarimetric SAR applications, also in view of future missions. Numerous experiments with real data from spaceborne platforms are shown, with the aim of giving an up-to-date and complete treatment of the unique benefits of fully polarimetric synthetic aperture radar data in five different domains: forest, agriculture, cryosphere, urban and oceans.
