TERRA- 1: Understanding The Terrestrial Environment - The Role of Earth Observations from Space (Hardcover): Paul Mather TERRA- 1: Understanding The Terrestrial Environment - The Role of Earth Observations from Space (Hardcover)
Paul Mather
R7,006 Discovery Miles 70 060 Ships in 12 - 17 working days

This book addresses opportunities for observation of earth surface processes using remote sensing from space. It should provide a data source for scientists studying global change. The challenges created by global environmental change demand research approaches that are worldwide in scope and interdisciplinary in application. This book is a response to the need for the interchange of ideas and experiences between researchers from those sciences studying the land surface of the earth, its form, and features, and remote sensing specialists. It is founded on the premise that attention should focus on the analysis of specific components of the earth system and on the synthesis of the findings of individual disciplines in terms of how the earth and its atmosphere function as an open system. Earth system science aims to identify how this system changes (both over human and geological timescales) and how such changes can be predicted. Reliable prediction requires scientific understanding, which in turn requires models, theories and data. Remote sensing is capable of providing such data on appropriate temporal and spatial scales.

When we look at some of the most pressing issues in environmental politics today, it is hard to avoid data technologies. Big data, artificial intelligence, and data dashboards all promise "revolutionary" advances in the speed and scale at which governments, corporations, conservationists, and even individuals can respond to environmental challenges. By bringing together scholars from geography, anthropology, science and technology studies, and ecology, The Nature of Data explores how the digital realm is a significant site in which environmental politics are waged. This collection as a whole makes the argument that we cannot fully understand the current conjuncture in critical, global environmental politics without understanding the role of data platforms, devices, standards, and institutions. In particular, The Nature of Data addresses the contested practices of making and maintaining data infrastructure, the imaginaries produced by data infrastructures, the relations between state and civil society that data infrastructure reworks, and the conditions under which technology can further socio-ecological justice instead of re-entrenching state and capitalist power. This innovative volume presents some of the first research in this new but rapidly growing subfield that addresses the role of data infrastructures in critical environmental politics.

Since the publication of Jerlov's classic volume on optical oceanography in 1968, the ability to predict or model the submarine light field, given measurements of the inherent optical properties of the ocean, has improved to the point that model fields are very close to measured fields. In the last three decades, remote sensing capabilities have fostered powerful models that can be inverted to estimate the inherent optical properties closely related to substances important for understanding global biological productivity, environmental quality, and most nearshore geophysical processes. This volume presents an eclectic blend of information on the theories, experiments, and instrumentation that now characterize the ways in which optical oceanography is studied. Through the course of this interdisciplinary work, the reader is led from the physical concepts of radiative transfer to the experimental techniques used in the lab and at sea, to process-oriented discussions of the biochemical mechanisms responsible for oceanic optical variability. The text will be of interest to researchers and students in physical and biological oceanography, biology, geophysics, limnology, atmospheric optics, and remote sensing of ocean and global climate change.

R1,515 Discovery Miles 15 150 Ships in 10 - 15 working days

Remote sensing has witnessed a renaissance as new sensor systems, data collection capabilities and image processing methodologies have expanded the technological capabilities of this science into new and important applications areas. Perhaps nowhere has this trend been more evident than in the study of earth environments. Within this broad application area remote sensing has proven to be an invaluable asset supporting timely data gathering at a range of synoptic scales, facilitating the mapping of complex landscapes and promoting the analysis of environmental process. Yet remote sensing s contribution to the study of human/environmental interaction is scattered throughout a rich and diverse literature spanning the social and physical sciences, which frustrates access to, and the sharing of the knowledge gained through, these recent advances, and inhibits the operational use of these methods and techniques in day to day environmental practice, a recognized gap that reduces the effectiveness of environmental management programs. The objective of this book is to address this gap and provide the synthesis of method and application that is currently missing in the environmental science, re-introducing remote sensing as an important decision-support technology.

As hyperspectral sensors, soft image classification strategies, nano- satellites, sensor webs and a myriad of other exciting technologies emerge from the research laboratories, a need exists to assemble the relevant principles, methods and proven applications into a focused discussion centered on environmental problem solving. In many ways, placing remote sensing more clearly into a problem-specific context moves us beyond the traditions commonly found in introductory textbooks and demonstrates the benefits that can be derived from this dynamic information technology.

This book expands on the material that would be the subject matter common to an introductory textbook in remote sensing by offering a more directed focus complemented by the theory and methods germane to the analysis and assessment of environment qualities and process.

Fully automated interpretation and understanding of remotely sensed data by a computer has been a challenge for many decades, and many approaches have been developed over the years. Significant advances in knowledge-based image understanding, machine learning and artificial intelligence has led to this topic being the focus of much research in recent years. This book highlights the different theoretical and application-oriented aspects and potential solutions to the topic of automated remote sensing data analysis. Thereby, both classical knowledge-based as well as modern machine learning-oriented concepts are described. A field such as this is specialized and dynamic and also interdisciplinary and multilayered. Written by an international team of experts, the book has therefore been split into parts dealing with the concepts and applications, and the focus is on elucidating the complementarity of different lines of research rather than providing the complete set of scientific approaches.Part A of this book gives insight into the basic theories and concepts of feature extraction, image understanding and the respective assessment strategies as well as into geometric, radiometric and sensor-related fundamentals of remote sensing technology. Part B focuses on various scientific and practical applications of remote sensing data analysis. These range from the automatic detailed reconstruction of complex 3D environments to visual tracking of objects in image sequences as well as monitoring natural and anthropogenic long-term processes on a regional scale. Part C sketches recent trends in automatic analysis of remote sensing data.
