This book was released on 2006 with total page 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.

Book Synopsis The Normalized Difference Vegetation Index by : Nathalie Pettorelli
Download or read book The Normalized Difference Vegetation Index written by Nathalie Pettorelli and published by OUP Oxford. This book was released on 2013-10-10 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a recent surge of interest in remote sensing and its use in ecology and conservation but this is the first book to focus explicitly on the NDVI (Normalised Difference Vegetation Index), a simple numerical indicator and powerful tool that can be used to assess spatio-temporal changes in green vegetation. The NDVI opens the possibility of addressing questions on scales inaccessible to ground-based methods alone; it is mostly freely available with global coverage over several decades. This novel text provides an authoritative overview of the principles and possible applications of the NDVI in ecology, environmental and wildlife management, and conservation. NDVI data can provide valuable information about temporal and spatial changes in vegetation distribution, productivity, and dynamics; allowing monitoring of habitat degradation and fragmentation, or assessment of the ecological effects of climatic disasters such as drought or fire. The NDVI has also provided ecologists with a promising way to couple vegetation with animal distribution, abundance, movement, survival and reproductive parameters. Over the last few decades, numerous studies have highlighted the potential key role of satellite data and the NDVI in macroecology, plant ecology, animal population dynamics, environmental monitoring, habitat selection and habitat use studies, and paleoecology. The chapters are organised around two sections: the first detailing vegetation indices and the NDVI, the principles behind the NDVI, its correlation with climate, the available NDVI datasets, and the possible complications and errors associated with the use of this satellite-based vegetation index. The second section discusses the possible applications of the NDVI in ecology, environmental and wildlife management, and conservation.

Book Synopsis Hyperspectral remote sensing of forest condition: estimating chlorophyll content in tolerant hardwoods by : Paul H. Sampson
Download or read book Hyperspectral remote sensing of forest condition: estimating chlorophyll content in tolerant hardwoods written by Paul H. Sampson and published by . This book was released on 2003 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectral features related to chlorophyll or other pigments are useful in identifying whether forests are healthy or are stressed to the point where productivity of the resource may be constrained. This study examines the use of compact airborne spectrographic imager (CASI) technology to estimate chlorophyll content in a managed tolerant hardwood forest in the Algoma region of Ontario. One objective was to determine whether chlorophyll content could be predicted following different harvesting practices. Another was to estimate chlorophyll content across seasons on a range of maple sites, with the overall aim of developing a prototype system for monitoring forest physiological condition. The first objective was addressed by examining CASI imagery & accompanying ground-truth data for the forest site, and the second was addressed by conducting change detection analysis of CASI imagery & leaf-based measurements obtained 1998-99 from a range of maple sites in the region.
Book Synopsis Photon-Vegetation Interactions by : Ranga B. Myneni
Download or read book Photon-Vegetation Interactions written by Ranga B. Myneni and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photon-Vegetation Interactions deals with the interaction of electromagnetic radiation with vegetation canopies. The approach to the various aspects is mainly theoretical and consequently the subject is being treated as a special branch of mathematical physics. A major emphasis is on the development of theoretical methods for determining the reflection function of vegetation canopies in optical remote sensing. Furthermore, the coupling of the radiative transfer theory with leaf photosynthesis to evaluate the productivity of vegetation canopies is treated as well as the theory of photon transport in phototropic and other biological media.
