This information ranges from demographic data, weather forecasts and sensor data, available transportation means, presence of helpful agents, land use and cover statistics or values, etc. Moreover, the emergency management process is dynamic as it involves several definite steps, described in standard procedures from which the Emergency Officer (EO) should not depart without good reason. Multiple agencies own the relevant data and possess parts of emergency related knowledge.Mon Jul 07 13:47:29 CEST 2008Computer790-93{SensorMap} for Wide-Area Sensor Webs402007v0805 spatial soap information paper sensor web ieee windows processing map storage microsoft network data application Geocentric Web interfaces such as Microsoft Virtual Earth and Google Maps are useful for visualizing spatially and geographically related data such as driving directions, directory entries, and weather and traffic conditions, to name a few. The desire to add useful information to these interfaces has led developers to create custom applications that overlay housing prices, crime rates, bus locations, and other data on top of browsable maps. These applications are possible due to useful APIs that Google Maps and Microsoft Virtual Earth publish to overlay location data on maps. We envision a new class of applications that relies on real-time sensor data and its mash-up with the geocentric Web to provide instantaneous environmental visibility and timely decision support.Mon Jul 07 13:47:29 CEST 2008it -- Information Technology15-16Kreuzungsverstehen -- Ein wissensbasierter Ansatz492007data analysis ai sensor location map processing v0805 paper traffic image video knowledge recognition Existierende Ansätze zur Fahrbahnerkennung arbeiten -- vermutlich prinzipbedingt -- auf jeweils nur kleinen Teilmengen der möglichen Fahrbahnkonfigurationen robust. Ein Schlüssel auf dem Weg zu allgemeingültig arbeitenden Verfahren liegt in der massiven Erhöhung der Menge des im Schätzprozess genutzten Vorwissens. Im Hinblick auf eine effiziente, nachvollzieh- und erweiterbare Beschreibung ist eine explizite Repräsentation solchen Wissens anzustreben. Im vorliegenden Beitrag wird eine konzeptuelle und eine geometrische Wissensrepräsentationen für den Diskursbereich Straßen und Kreuzungen vorgestellt. Deren Parameter werden gemeinsam mittels eines Multihypothesen-Ansatzes geschätzt, dessen Eingangsdaten handelsübliche digitale Karten sowie verschiedene videobasierte Objektdetektoren sind. Zur Verifikation der Hypothesen werden die Vorzugsrichtungen der lokalen Textur im Bereich der erwarteten Fahrspurberandungen ausgewertet. Dabei kann gleichzeitig die Messunsicherheit der zur Bildprojektion genutzten Schätzung der Lage des Kamerakoordinatensystems reduziert werden. Junction Understanding---A Knowledge Based Approach: The road recognition problem has been solved robustly only for small, often simplified subsets of possible road configurations. A massive augmentation of the amount of used prior knowledge could pave the way towards generally valid estimators. An explicit representation of such knowledge will additionally lead to an efficient, understandable and therefore extendible system. We present a conceptual and a geometrical knowledge representation for the Roads&Junctions domain of discourse. Its parameters are estimated using a multi hypotheses approach. A commercially available digital map and a set of video based object detectors serve as input data. The resulting hypotheses are verified by evaluating the preferred orientations of local texture around the expected position of the lane dividers. The estimate of the camera coordinate system's pose, which is used for image projection, is updated simultaneously.Mon Jul 07 13:47:29 CEST 2008Internet Computing138-44Emergency Response Applications: Dynamic Plume Modeling and Real-Time Routing122008spatial v0805 crisis map paper management information ieee In a crisis situation, toxic gas can be released into the air, blocking routes for emergency responders. Rescue workers must be able to compute the shortest and safest paths in the presence of toxic gas dispersions that move dynamically with changing wind speed and direction. To model this, the authors developed weather retriever software, which fetches weather details about a particular location from the Internet and acts as the station for atmospheric measurements for the Aloha plume-modeling software. The authors also explored options for displaying this dynamic plume on a geographic map.
