Linking sensor data why to what and how
Once the user clicks on a location, all the sensors located nearby are displayed on a map. Users can click to get more information about the sensor, such as the sensor capabilities, coordinates and also current weather observations. This approach for discovering sensors uses a standard service interface to query Linked Sensor Data, a semantic sensor network middleware that includes a sensor registry and a sensor discovery service that extends the OGC Sensor Web Enablement. The application gives access to the following datasets sourced from MesoWest , a project within the Department of Meterology at the University of Utah that has been aggregating weather data since This intuitive discovery is possible by linking concepts from Linked Sensor Data knowledge base to concepts in GeoNames knowledge base.
This linking of concepts is a fundamental principle of Linked Data. A number of government, corporate, and academic organizations are collecting enormous amounts of data provided by environmental sensors. However, this data is too often locked within organizations and underutilized by the greater community.
With such a framework, organizations can make large amounts of sensor data openly accessible, thus allowing greater opportunity for utilization and analysis. Publication Type. More Filters. Using Linked Data in a heterogeneous Sensor Web: challenges, experiments and lessons learned.

While clients compliant to these standards have access to the generated sensor data, it remains partially hidden from other knowledge infrastructures building on higher-level W3C standards. To overcome this problem, it has been proposed to make sensor data accessible using Linked Data principles and RESTful services.
This position paper discusses the embedding of such data into the Linked Data cloud with a focus on the outgoing links that hook them up with other data sources. We outline how such links can be generated in a semi-automatic way, and argue why curation of the links is required.
