Book Synopsis Using NAIP Imagery to Estimate Tree Canopy Cover by : Abigail Schaaf
Download or read book Using NAIP Imagery to Estimate Tree Canopy Cover written by Abigail Schaaf and published by . This book was released on 2010 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper highlights the likelihood of overestimating canopy cover using any airborne imagerywith particular focus on National Agriculture Imagery Program (NAIP) imagery. This study compared canopy-cover estimates from NAIP imagery and resource photography acquired during the same year. Four sites were selected based on a visual evaluation of apparent canopy-cover differences between the two types of imagery and used to estimate tree canopy cover. The estimates of canopy cover samples from NAIP imagery were about 45 percent higher than those collected from resource photography. Because NAIP is the only high-resolution digital imagery available over the contiguous U.S. (and is streamed via Image Server to all Forest Service personnel), it is an important resource for forest mapping, planning, and monitoring. However, it does have limitations, specifically estimating canopy cover. The results from this investigation need to be considered before deciding to use NAIP imagery to determine tree canopy cover."

Book Synopsis Forest Attributes from Multi-angle Multi-date Remotely Sensed Data by :
Download or read book Forest Attributes from Multi-angle Multi-date Remotely Sensed Data written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-Angle, Multi-Date, Hyperspectral imagery of forests have been used to provide accurate estimates of the canopy characteristics. This thesis investigated the influence of various forest attributes on the spectral reflectance over time and view direction. The Compact High Resolution Imaging Spectrometer (CHRIS) is aboard the ESA PROBA satellite. The revisits of the CHRIS multi-angle images have been used to improve the accuracies of forest species recognition and stand densities compared to a nadir view only. Multi-angle data for CHRIS analysis of forest species produced higher accuracy and were easier to obtain than multi-date date. 5-Scale, a radiative transfer model, and CHRIS data have been compared as inputs into Partial Least Squares (PLS), a fullspectrum analytical method that offers relations between forest stand parameters and the resulting spectra. The resulting coefficients highlight where (view angle and spectral regions) within the multi-angle spectra contributed to estimating the various forest parameters. Methodology of collecting spectral calibration data in the field and the unique pre-processing challenges have been described.

Book Synopsis Evaluating Forest Volume Estimation at Barksdale Air Force Base Using Lidar and Multispectral Imagery by : Richard Edward Brooks
Download or read book Evaluating Forest Volume Estimation at Barksdale Air Force Base Using Lidar and Multispectral Imagery written by Richard Edward Brooks and published by . This book was released on 2009 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimating timber volume from a field perspective, with field plots occasionally falling within remote and inaccessible areas, can be a costly and timely endeavor. Remote sensing, with its ability to record information at both the local and regional scale, offers an alternative to traditional field based measurements. Studies have shown that remotely sensed vegetation biomass indices (e.g. NDVI) derived from mid-spatial resolution digital imagery (e.g. Landsat TM, 30-meters), after being corrected for atmospheric effects, topographical differences and shadow, were highly correlated with timber volume. With the recent advent of high spatial resolution digital imagery from the IKONOS and QuickBird satellites providing more textural information about a forest canopy, with spatial resolutions of 4 meters and 2.44 meters for multispectral data respectively, the opportunity to assess forest volume from a distance at a much finer scale has increased. Additionally Lidar (light detection and ranging) is a relatively new remote sensing technology that can accurately estimate the 3-dimensional structure of forest vegetation which is related to forest volume and offers an alternative to ground based measurement of remotely sensed multispectral data.

Book Synopsis Remote Sensing Advances in Biodiversity and Ecosystem Functioning Research by : Zhouyuan Li
Download or read book Remote Sensing Advances in Biodiversity and Ecosystem Functioning Research written by Zhouyuan Li and published by Frontiers Media SA. This book was released on 2024-02-06 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different dimensions of biodiversity are increasingly appreciated as critical for maintaining the functions of ecosystems and their services to humans. More recently, with the emergence of functional biogeography, functional diversity is of particular interest due to its strong links with ecosystem processes such as carbon, water and energy exchange, and climate mitigation. The multi-form diversity varies in space and time. Understanding this variation across scales is important for tracking the resilience of Earth’s ecosystem, and the information on the ecosystem structural features provides necessary foundations for monitoring, predicting the ecosystem functioning patterns and process of ecosystems from individual unit to its whole in a holistic manner. In recent, the high-resolution, high-throughput, non-intrusive, and large-scale data on biodiversity monitoring and measurement are becoming a new trend toward enhancing the efficiency and coherency in ecological discovery. Still, the available multi-scale data on multi-dimensional diversity are incomplete and non-representative taxonomically, geographically and temporally. Although the studies on functional traits and their relations with function continue to grow, local observations on functional traits are limited. Recently, remote sensing has proved to be a critical technology for addressing this research gap. Air- and satellite-borne spectrometers at different levels could develop novel diversity measurements and alternati

Download or read book Fine Resolution Remote Sensing of Species in Terrestrial and Coastal Ecosystems written by Qi Chen and published by Routledge. This book was released on 2021-09-09 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed and accurate information on the spatial distribution of individual species over large spatial extents and over multiple time periods is critical for rapid response and effective management of environmental change. The twenty first century has witnessed a rapid development in both fine resolution sensors and statistical theories and techniques. These innovations hold great potential for improved accuracy of species mapping using remote sensing. Fine Resolution Remote Sensing of Species in Terrestrial and Coastal Ecosystems is a collection of eight cutting-edge studies of fine spatial resolution remote sensing, including species mapping of biogenic and coral reefs, seagrasses, salt and freshwater marshes, and grasslands. The studies illustrate the power of fine resolution imagery for species identification, as well as the value of unmanned aerial vehicle (UAV) imagery as an ideal source of high-quality reference data at the species level. The studies also highlight the benefit of LiDAR (Light Detection and Ranging) data for species identification, and how this varies depending on the species of interest as well as the nature of the context in which the species is found. The broad range of applications explored in the book demonstrates the major contribution of remote sensing to species-level terrestrial and coastal ecosystem studies as well as the potential for future advances. The chapters in this book were originally published as a special issue of the International Journal of Remote Sensing.

Book Synopsis Forestry Applications of Unmanned Aerial Vehicles (UAVs) 2019 by : Alessandro Matese
Download or read book Forestry Applications of Unmanned Aerial Vehicles (UAVs) 2019 written by Alessandro Matese and published by MDPI. This book was released on 2020-11-23 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unmanned aerial vehicles (UAVs) are new platforms that have been increasingly used in the last few years for forestry applications that benefit from the added value of flexibility, low cost, reliability, autonomy, and capability of timely provision of high-resolution data. The main adopted image-based technologies are RGB, multispectral, and thermal infrared. LiDAR sensors are becoming commonly used to improve the estimation of relevant plant traits. In comparison with other permanent ecosystems, forests are particularly affected by climatic changes due to the longevity of the trees, and the primary objective is the conservation and protection of forests. Nevertheless, forestry and agriculture involve the cultivation of renewable raw materials, with the difference that forestry is less tied to economic aspects and this is reflected by the delay in using new monitoring technologies. The main forestry applications are aimed toward inventory of resources, map diseases, species classification, fire monitoring, and spatial gap estimation. This Special Issue focuses on new technologies (UAV and sensors) and innovative data elaboration methodologies (object recognition and machine vision) for applications in forestry.
