Vision of the Sensor Web

Objective of the SN & WE programme • Discovery of sensor systems, observations, and observation processes through web • Determination of a sensor’s capabilities and quality of measurements • Access to sensor parameters that automatically allow Access to sensor parameters that automatically allow software to process and geolocate observations • Retrieval of real-time or time-series observations and coverages in standard encodings i t d d di • Tasking of sensors to acquire observations of interest • • Subscription to and publishing of alerts to be issued by Subscription to and publishing of alerts to be issued by sensors or sensor services based upon certain criteria • Within the SWE initiative, the enablement of such sensor webs is being pursued through the establishment of several encodings for describing sensors and sensor observations, and through several standard interface definitions for web g services.

Why SWE is required ? • It enables various applications like • Intelligent Transport System • Intelligent Transport System • Weather models, environmental monitoring systems, Public safety & Management Public safety & Management • Unified observational systems, maintenance and management t • Standard observational data sets • Efficient management of resources • Create once and use many times • Integration of various MODELS, Geo-spatial data and on-line observational data enables simulation and possible alert generation

Enabling Mechanisms • National Spatial Data Infrastructure • National Spatial Data Infrastructure – Indian Context Indian Context • Availability of Geo-spatial Data • Standards – OGC, ISO • Web technologies have matured • Considerably consistent web infrastructure is in place • Established ICT expertise including sensors • Proactive R&D institutions and people Proactive R&D institutions and people • DST is a member of OGC and Board of Directors
