3 ISTIMES main goals Development of new and advanced electromagnetic sensors for non-destructive monitoring of the critical transport infrastructures. Design, assessment and promotion of an ICT-based system, exploiting distributed and local sensors. Design and implementation of a monitoring system that allows a high situation awareness in order to provide updated, quasi-real time and detailed information and images of the infrastructure status. Sensor Technologies Researchers Citize ns Decision-makers Discovery service Processing service Notification service Data access service Data publishing service Sensor tasking service ICT based system

4 Scales of EM Sensing techniques Global Vision: to monitor wide areas including ground deformation, the overall infrastructure (its status included) and the surrounding environment Local scale: to provide insight on the status of the infrastructure itself by giving a detailed local information on more sensitive and damaged part of the infrastructure. Data integration and correlation: to couple technologies of both visions in order to assess and monitor the infrastructures during normal operations and after the crisis event.

6 Identified approach Change the traditional data-centric approach Advanced service-based approach Focus on multidisciplinary interoperability Shift from system to infrastructure or system of systems Spatial Data Infrastructure (SDI)

11 Approach ISTIMES exploits an open networked architecture that can accommodate a wide range of sensors, static and mobile, and can easily scale up to allow the integration of additional sensors and interfacing with other networks. ISTIMES relies on heterogeneous state-of-the-art electromagnetic terrestrial sensors, supported by specific satellite measurements. ISTIMES integrates electromagnetic technologies with new information and telecommunications systems enabling remotely controlled monitoring and surveillance and real time data imaging of the critical transport infrastructures. ISTIMES use the SWE that offers methods for sensor system discovery and control based on the Web and OGC s framework for geo-processing

12 Project Overview OGC SWE vision: Sensors will be Web accessible Sensors and sensor data will be discoverable Sensors will be self-describing to humans and software (using a standard encoding) Most sensor observations will be easily accessible in a timely fashion over the Web Sensor Observation Service - Defines a standard Web interface for accessing observation data from sensor systems Sensor Planning Service - Defines a standard Web interface for preparing collection feasibility plans and a service to process collection requests for a sensor or sensor constellation

13 Standards SWE Common Data Model 2.0 (08-094) Observations & Measurements O&M 2.0 Sensor Model Language SensorML 2.0 SWE Service Model (SWES, ) Sensor Observation Service SOS 2.0 (10-037) Sensor Planning Service SPS 2.0 (09-000)

14 O&M _ SOS _ SPS O&M: Provides a conceptual model and XML encoding for sensor observations and measurements SOS: Provides a standard Web interface by which clients can access sensor measurement outputs from sensor systems SPS: Defines a standard Web interface by which clients can prepare collection feasibility plans and a service to process collection requests for a sensor or sensor constellation

15 SensorML Provides an information model and encodings for discovering, querying, and controlling of Web sensors Establishes a standard schema for metadata describing sensors, sensor platforms, and sensor tasking interfaces Enables specifying location and orientation of platforms and sensors (either directly within a CRS or relative to a local CS) Provides a functional model of a sensor system

17 User list review Decision maker user in charge of decision making for what concerns the security and maintenance of the infrastructure under monitoring; Scientific user user with scientific expertise in the sensor measurements and/or in the physical parameters of the infrastructure under monitoring; Generic user any web user browsing to the public section of the system web application; Sensor operator user operating a sensor and performing the actual data acquisition, stored and processed by the system to monitor the infrastructure; System administrator user in charge of system administration from an ICT point of view, e.g. web master, sysop, sys-admin.

18 Schematic view of users

19 Information view The data models and formats relevant to the ISTIMES system are: SensorML for sensor description; Observations and Measurements (O&M) for acquisition description and encoding (through appropriate application schemas); GeoTIFF for map as well as coverage data (e.g. satellite datasets).

25 User Interface Liferay Portal: is a free and open source enterprise portal written in Java allows users to set up features common to websites is fundamentally constructed of functional units called portalets is sometimes described as a content management framework

27 User Interface

28 Fiber Optic SOS server: provides a standard way to access observations and measurements acquired by sensors and sensor system. SPS server: provides method for planning, scheduling and tasking sensor in standard way. OGC client for Fiber sensor: In order to receive and manage planning messages (from SPS service) and to send observation messages (to SOS service), a daemon has to be up and running on Fiber sensor hardware.
