This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial photographs are a crucial tool for ecological monitoring and management. New approaches for aerial photograph analysis are needed because of several existing (and anticipated) challenges associated with traditional analysis techniques. The goal of this thesis is to provide a synthesis of the valuable, and often unique, ecological information available from aerial photographs, and to explore the utility of novel image analysis approaches to extract this information. This research is organized to reflect the future of aerial photography as a discipline. In chapter two, I review the benefits and challenges of using aerial photographs for ecological management. The traditional framework used to classify aerial photographs, as well as sources of error are described within the context of the diverse ecological questions that can be addressed using aerial photography. The need for new approaches to analyze aerial photographs is emphasized throughout this chapter. In chapter three, I compare manual interpretation to an automated approach (combining object-based analysis and classification tree modeling), for five classification schemes routinely used in British Columbia. Automated approaches hold potential for replicating certain aspects of the manual process (such as the delineation of polygons), as automated and manually-delineated objects display few statistical differences. Automated classification accuracy is highly variable, with individual class accuracies ranging from 0- 4%; however the overall accuracy of several classification schemes exceeded 60%, suggesting certain schemes are well suited to automated analysis. In chapter four, object-based analysis is applied to historic aerial photographs to better quantify spatial heterogeneity, a concept fundamental to the field of landscape ecology. My results suggest sixteen independent factors are needed to describe baseline levels of landscape heterogeneity, including several factors not previously identified by t.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the rich, but under-utilised and in parts inaccessible, archival historic aerial imagery, traditional photographs and those captured from satellites, for the exploration and management of cultural heritage. An unparalleled resource, for archaeologists and all with an interest in landscapes, images spanning the second half of the 20th century provide an unrivalled means of documenting and understanding change and informing the study of the past. Case studies, written by leading experts in their fields, illustrate the applications of this imagery across a wide range of heritage issues, from prehistoric cultivation and settlement patterns, to the impact of recent landscape change. Contemporary environmental and land use issues are also dealt with, in a volume that will be of interest to archaeologists, historians, geographers and those in related disciplines.
Download or read book Landscape Ecology in Theory and Practice written by Monica G. Turner and published by Springer Science & Business Media. This book was released on 2003-05-20 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading.

Download or read book Novel Aerial Photography as an Aid to Sampling Secondary Structure in Pine Stands written by Patrick Anthony Teti and published by . This book was released on 2009 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project describes a new method for sampling secondary structure in beetle-attacked pine stands and reports on a test of its accuracy. The method consists of interpreting aerial photos taken when snow covers the forest floor and the sky is overcast. This report describes the results of a preliminary accuracy test of sampling secondary structure by interpreting aerial photos taken during winter overcast conditions. Overlapping sequential photos of previously selected plots were georeferenced, plot geometry was overlaid, photos were interpreted, and the accuracy of interpretation was determined by field checking the accuracy of tree classification was assessed by determining errors of omission and commission for each tree based on whether it was correctly defined as inside the plot and whether it was a green conifer. The accuracy of measuring crown diameters of green conifers was also assessed by direct comparison of field and photo measurements. The work includes information on materials and methods, results and discussion, the authors' conclusions, as well as recommendations.--Includes text from document.

Available in PDF, EPUB and Kindle. Book excerpt: Human activity during the Anthropocene has transformed landscapes worldwide on a scale that rivals or exceeds even the largest of natural forces. Landscape ecology has emerged as a science to investigate the interactions between natural and anthropogenic landscapes and ecological processes across a wide range of scales and systems: from the effects of habitat or resource distributions on the individual movements, gene flow, and population dynamics of plants and animals; to the human alteration of landscapes affecting the structure of biological communities and the functioning of entire ecosystems; to the sustainable management of natural resources and the ecosystem goods and services upon which society depends. This novel and comprehensive text presents the principles, theory, methods, and applications of landscape ecology in an engaging and accessible format that is supplemented by numerous examples and case studies from a variety of systems, including freshwater and marine "scapes".
