This book brings together a collection of invited interdisciplinary persp- tives on the recent topic of Object-based Image Analysis (OBIA). Its c- st tent is based on select papers from the 1 OBIA International Conference held in Salzburg in July 2006, and is enriched by several invited chapters. All submissions have passed through a blind peer-review process resulting in what we believe is a timely volume of the highest scientific, theoretical and technical standards. The concept of OBIA first gained widespread interest within the GIScience (Geographic Information Science) community circa 2000, with the advent of the first commercial software for what was then termed ‘obje- oriented image analysis’. However, it is widely agreed that OBIA builds on older segmentation, edge-detection and classification concepts that have been used in remote sensing image analysis for several decades. Nevert- less, its emergence has provided a new critical bridge to spatial concepts applied in multiscale landscape analysis, Geographic Information Systems (GIS) and the synergy between image-objects and their radiometric char- teristics and analyses in Earth Observation data (EO).

Cities and towns are the original producers of many of the global environmental problems related to waste disposal, and air and water pollution. There is a rapidly growing need for technologies that will enable monitoring of the world’s natural resources and urban assets, and managing exposure to natural and man-made risks. The Group on Earth Observation (GEO) calls for strengthening the cooperation and coordination among global observing systems and research programs. Global Urban Monitoring and Assessment through Earth Observation introduces this important international collaborative effort, reviews the current state of global urban remote sensing, and expands on future directions in the field. The book reviews the current state of global urban monitoring, assessment, modeling, and prediction through Earth observation and related technologies. It then introduces GEO’s important international collaborative effort—Global Urban Observation and Information Task—and the current state of global urban remote sensing and future directions. It explores groundbreaking work in urban remote sensing and examines how it could contribute to the development of innovative concepts and techniques for sustainable urban development. Despite significant progress in recent years, there remain substantial gaps in ongoing national, regional, and global efforts to address environmental challenges. Edited by a well-known expert in the field of remote sensing, GIS, and other geospatial technologies, this book addresses the gaps in an effective and long-term manner, highlighting the importance of increased coordination and networking among major stakeholders and of working together with other key international mechanisms. Drawing on the expertise of pioneers in the field from across the globe, the book details emerging research in the theory, methods, and techniques of urban remote sensing that provide insight into how to solve the major issues of sustainable development—one of the most important issues facing society in the future.

Healing Insanity: A Study of Igbo Medicine in Contemporary Nigeria is an original and in-depth study on endogenous medical system in an African society. It is craftily written and provides solid insight, through case studies and theory, into how insanity affects patients and the society. Particularly, it explores various collective representations and strategies regarding insanity and healing as it examines the healing institutions, healers, and ritual cults. The central question is, given the patterns of healing, how do the Igbo shape the incidence and symptoms of insanity, define its aetiology, and provide healers with culture-specific resources and skills to address this illness? The focus became increasingly centred on bodily semantics and endogenous knowledge systems and practices. Dr. Patrick Iroegbu's work is a very valuable and rare study and has appeared at a desirable time. It is, for an African society, a comprehensive study of the many ways Igbo people, in their practical, routinelike attitudes and body-centred experiences, as well as in their more reflective aetiologic knowledge and healing institutions, relate to the phenomenon of insanity, or ara, in the cultural parlance. As the first of its kind, reminiscent of, and assured by, the various remarks of Igbo scholars and leaders at various meetings and discourses, the task this work has set out to accomplish is a very brave one. The author's account of his fieldwork experiences and adopted techniques illustrates his initiation, revealing him as a genuine ethnographer who is a "friend of people and at ease with his field." With both the far-seeing and inspiring analysis of Igbo medicine, life, and culture accounted for in the work, the book stands out for ethnographers, teachers, students, leaders, policymakers, and the general public. This is a book that deserves to be read as it shapes the critical path toward understanding ways of healing insanity in a culture-specific context, crosscutting perspectives for a relationship between indigenous healing and the biomedical sphere. Prof. René Devisch (Africa Research Centre, University of Leuven) This book is written with a clear purpose for everyone to read to understand and heal insanity and indeed provides a thick piece of cultural philosophy and vernacular of Igbo medicine in hopes of putting cultural wisdom in pursuit of integral health care development. Prof. Pantaleon Iroegbu (Professor of Philosophy, Major-Seminary, Ekpoma, January 2006) To read this book, as I did, is to get the benefit of Dr. Patrick Iroegbu's ethnographic insight for an archetypical African healing system in Igboland. It offers a fascinating theory of symbolic release that speaks of African symbolic action and knowledge system. Dr. Paul Komba, Esq. (University of Cambridge)

Generating a satisfactory classification image from remote sensing data is not a straightforward task. Many factors contribute to this difficulty including the characteristics of a study area, availability of suitable remote sensing data, ancillary and ground reference data, proper use of variables and classification algorithms, and the analyst’s experience. An authoritative text, Advances in Environmental Remote Sensing: Sensors, Algorithms, and Applications compiles comprehensive review articles to examine the developments in concepts, methods, techniques, and applications as well as focused articles and case studies on the latest on a particular topic. Divided into four sections, the first deals with various sensors, systems, or sensing operations using different regions of wavelengths. Drawing on the data and lessons learned from the U.S. Landsat remote sensing programs, it reviews key concepts, methods, and practical uses of particular sensors/sensing systems. Section II presents new developments in algorithms and techniques, specifically in image preprocessing, thematic information extraction, and digital change detection. It gives correction algorithms for hyperspectral, thermal, and multispectral sensors, discusses the combined method for performing topographic and atmospheric corrections, and provides examples of correcting non-standard atmospheric conditions, including haze, cirrus, and cloud shadow. Section III focuses on remote sensing of vegetation and related features of the Earth’s surface. It reviews advancements in the remote sensing of ecosystem structure, process, and function, and notes important trade-offs and compromises in characterizing ecosystems from space related to spatial, spectral, and temporal resolutions of the imaging sensors. It discusses the mismatch between leaf-level and species-level ecological variables and satellite spatial resolutions and the resulting difficulties in validating satellite-derived products. Finally, Section IV examines developments in the remote sensing of air, water, and other terrestrial features, reviews MODIS algorithms for aerosol retrieval at both global and local scales, and demonstrates the retrieval of aerosol optical thickness (AOT). This section rounds out coverage with a look at remote sensing approaches to measure the urban environment and examines the most important concepts and recent research.
