Real-time monitoring of urban dynamics, which is widely unexplored, has recently received a lot of attention due to the fast rise of inexpensive pervasive sensor technologies. Following the comprehensive vision of a “digital skin for planet Earth” by Neil Gross (1999), it can be presumed that geo-sensor web deployments will experience a considerable boost within the coming years, as pervasive sensing has recently become feasible and affordable. This enriches knowledge about our environment with uncharted real-time information layers.This book focuses on pervasive sensing in urban environments, which poses very particular challenges – as well technical and technological ones, as socio-political and privacy-related ones. The Live Geography approach presented in this book seeks to tackle these challenges with an open sensing infrastructure for urban monitoring applications. The system makes extensive use of open (geospatial) standards throughout the entire process chain – from sensor fusion to data analysis, Complex Event Processing (CEP), alerting, and finally visualisation.The thesis discusses the implemented technical infrastructure as well as how the methodology can potentially influence the city and its inhabitants by “making the abstract real”. In other words, the thesis illustrates how pervasive monitoring infrastructures can change urban social interactions and people’s short-term behaviour, and which issues are related to establishing such systems.

PrefaceSensors have become a vital part of everyday lives. We are surrounded by a greatvariety of small sensing devices, hidden in our cars, homes, surrounding energyinfrastructures, cell phones, and so forth. These sensors extend our human senses andassist us in perceiving our environment in a more holistic way by revealing “unseen”information layers.But how can we leverage this kind of data? These invisible sensed data have to bemade perceivable to the eye – or other human senses. However, creating high qualityinformation layers from raw sensor data is not trivial. User-specific needs in terms ofvisualisation, data filtering, context presentation, and the way or the medium to conveyinformation have to be carefully assessed.Moreover, my experiences showed that an increasing number of sensor networksare emerging, but their data are not combinable due to monolithic and closedmeasurement systems. This prevents trans-domain usage of sensor data and thus callsfor new paradigms in terms of data accessibility, information provision and policymakingfor real-time data availability.This thesis is dedicated to tackle that issue from a technical viewpoint. After thebeginning of this thesis, also a few large-scale international research projects originatedfrom similar needs. The cooperation with these projects was a valuable help fordefining the focus of this thesis, but also a productive interplay by contribution of ideasin both directions.As this thesis has been conceived over a period of several years, significant piecesof the research outcomes have already been published in a variety of scientific journalsand conference proceedings. These papers are listed below. It shall be noted that somesub-parts of the thesis have been directly transferred into scientific papers. Smallfractions have been inherited without modification to ensure optimum readability.Mainly, the first three papers of the list below have originated from thesis chapters 1(Introduction), 6 ( “Live Geography” Approach), 7 (Implementation of the LiveGeography Approach) and 9 (Discussion and Conclusion). The other papers haveemerged from different smaller parts of this thesis integrating ideas, concepts and shorttext passages.
