Abstract

Over the past two decades, the oil sands region of northeastern Alberta has been the site of unprecedented levels of development. Alberta's Lower Athabasca Basin tells a fascinating story of how a catastrophic ice age flood left behind a unique landscape in the Lower Athabasca Basin, one that made deposits of bitumen available for surface mining. Less well known is the discovery that this flood also produced an environment that supported perhaps the most intensive use of boreal forest resources by prehistoric Native people yet recognized in Canada. Studies undertaken to meet the conservation requirements of the Alberta Historical Resources Act have yielded a rich and varied record of prehistoric habitation and activity in the oil sands area. Evidence from between 9,500 and 5,000 years ago—the result of several major excavations—has confirmed extensive human use of the region's resources, while important contextual information provided by key ecological and palaeoenvironmental studies has deepened our understanding of how the region's early inhabitants interacted with the landscape. Touching on various elements of this rich environmental and archaeological record, the contributors to this volume use the evidence gained through research and compliance studies to offer new insights into human and natural history. They also examine the challenges of managing this irreplaceable heritage resource in the face of ongoing development.Contributors: Alwynne B. Beaudoin, Janet Blakey, Luc Bouchet, James A.

Abstract

Recently, growing interest in the use of remote sensing imagery has appeared to provide synoptic maps of water quality parameters in coastal and inner water ecosystems;, monitoring of complex land ecosystems for biodiversity conservation; precision agriculture for the management of soils, crops, and pests; urban planning; disaster monitoring, etc. However, for these maps to achieve their full potential, it is important to engage in periodic monitoring and analysis of multi-temporal changes. In this context, very high resolution (VHR) satellite-based optical, infrared, and radar imaging instruments provide reliable information to implement spatially-based conservation actions. Moreover, they enable observations of parameters of our environment at greater broader spatial and finer temporal scales than those allowed through field observation alone. In this sense, recent very high resolution satellite technologies and image processing algorithms present the opportunity to develop quantitative techniques that have the potential to improve upon traditional techniques in terms of cost, mapping fidelity, and objectivity. Typical applications include multi-temporal classification, recognition and tracking of specific patterns, multisensor data fusion, analysis of land/marine ecosystem processes and environment monitoring, etc. This book aims to collect new developments, methodologies, and applications of very high resolution satellite data for remote sensing. The works selected provide to the research community the most recent advances on all aspects of VHR satellite remote sensing.
