    Monitoring of a Transport Infrastructure via a Sensor-enabled SDI
    (Innovations in Sharing Environmental Observations and Information, 2011) Bigagli, Lorenzo; Nativi, Stefano; Santoro, Mattia; Boldrini, Enrico; Mazzetti, Paolo
    In the framework of the FP7 ISTIMES project (Integrated System for Transport Infrastructures Surveillance and Monitoring by Electromagnetic Sensing), we have designed a distributed, real-time, Web-based information system for sensor-based transport infrastructures monitoring applications. The overall aim of the ISTIMES project is to make critical transport infrastructures more reliable and safe, providing real-time, detailed information and imagery of the infrastructure status, to improve decision support for security stakeholders, by means of non-destructive electromagnetic monitoring, exploiting heterogeneous state-of-the-art insitu sensors and specific satellite measurements. From an ICT point of view, ISTIMES aims at the design of an open networked architecture capable of integrating measurements from a wide range of remote and in-situ sensors. Our main contributions have regarded: the formalization of system users and use-cases; the design of the service infrastructure, including peculiar value-added mediation services; the identification of the system components and of possible technological implementations. The ISTIMES system is a middleware framework founded on a Spatial Data Infrastructure, hence enabling the implementation of individual test-bed applications, customized to the transport infrastructure of interest. ISTIMES is an ideal test case for the Event Architecture paradigm, which naturally accommodates asynchronous events from disparate sources, e.g. a constellation of autonomous sensors deployed onto an infrastructure. Besides, ISTIMES constitutes a valuable real-world application for the current best practices and standards in multi-sensors, real-time monitoring systems, and its feedback may contribute to their future evolution.

    The Multi-Disciplinary Interoperability Challenge
    (Innovations in Sharing Environmental Observations and Information, 2011) Craglia, Massimo; Nativi, Stefano; Diaz, Laura; Vaccari, Lorenzino
    The implementation of the INSPIRE Directive in Europe and similar efforts around the globe to develop spatial data infrastructures and global systems of systems have been focusing largely on the adoption of agreed technologies, standards, and specifications to meet the (systems) interoperability challenge. Addressing the key scientific challenges of humanity in the 21st century requires however a much increased multi-disciplinary effort, which in turn makes more complex demands on the type of systems and arrangements needed to support it. This paper analyses the challenges for multi-disciplinary interoperability using the experience of the EuroGEOSS research project (www.eurogeoss.eu). It argues that multi-disciplinarity requires mutual understanding of requirements, methods, theoretical underpinning and tacit knowledge. For this purpose it is necessary to move from a focus on data discovery and access, to one that puts emphasis on the way in which different disciplines frame a problem and use data and analytical models and processes to find one or more possible solutions. In other words, we need to elicit and document analytical models, and make reference to their theoretical bases, so that researchers from different disciplines can have a bridge to understand and collaborate meaningfully across the disciplinary divide.
