Copyright 2004 CRC Press LLC GeoSensor Networks Copyright 2004 CRC Press LLC Preface Advances in sensor technology and deployment strategies are revolutionizing the way that geospatial information is collected and analyzed. For example cameras and GPS sensors on-board static or mobile platforms have the ability to provide continuous streams of geospatially-rich information. Furthermore with the advent of nano-technology it becomes feasible and economically viable to develop and deploy low-cost low-power devices that are generalpurpose computing platforms with multi-purpose on-board sensing and wireless communications capabilities. All these types of sensors may act collaboratively as nodes within broader network configurations. Such configurations may range in scale from few cameras monitoring traffic to thousands of nodes monitoring an ecosystem. When drafting the call for papers that resulted in this book we left on purpose the term geosensor network somewhat undefined as we wanted it to be determined by the research communities that are providing the pieces of its puzzle. However despite this lack of a formal definition there is a very clear inherent understanding of what a geosensor network is. In geosensor networks the geospatial content of the information collected by a sensor network is fundamental for the analysis of feeds. Thus a geosensor network may be loosely defined as a sensor network that monitors phenomena in a geographic space. This space may range in scale from the confined environment of a room to the highly complex dynamics of a large ecosystem. With this emerging sensor deployment reality we are faced with substantial research challenges related to the collection management analysis and delivery of real-time geospatial information using distributed geosensor networks. This book offers a collection of papers that address some of .
