At the Internet of Things workshop of the OGC TC meeting in Brussels, we presented the SenseBox project which we are conducting together with the SWSL group at the Institute for Geoinformatics of the Uni Münster.
Besides demonstrating the SenseBox project, we gave recommendations for bringing the Internet (or better Web) of Things field together with the standardization efforts at OGC. Standardized REST APIs for things as well as well-defined JSON encodings for exchanging data about / from things could be an interesting contribution of the OGC to this emerging technology field. Similar suggestions were made by other particiapnts. E.g., Ben Pirt from the Internet of Things platform pachube announced their interest in OGC and standardized protocols for the Internet of Things.

Please find below the presented slides.

At the OGC TC meeting which took place this week in Brussels, our new SOS extension for the GeoServices REST API was presented. This extension, which is based on ArcGIS Server 10.1, embeds the functionality of a Sensor Observation Service (SOS) into the GeoServices REST API. The GeoServices REST API is currently making its way through the OGC standardization process.

The implementation of the SOS extension for the GeoServices REST API based on ArcGIS Server is developed for a project with the European Environment Agency (EEA). With the help of this software, the provision of Europe’s environmental data shall be facilitated – accessing data such as Ozone, noise, or water quality will become easier in future.

Please find below the presentation hold at the OGC TC meeting. The slides introduce to the project with EEA and the SOS extension.

Being at the FOSS4G conference in Denver, I just hold a presentation about our Thin SWE Client for the OGC Sensor Observation Service. The functionality of the client is focused on the display of time series data. This comprises a diagram view with comfortable navigation mechanisms (e.g. an overview time series, panning, zooming, etc.). In addition a table view showing all measured values belonging to a selected time series, as well as a map overview for displaying the sensor locations are included. This display functionality is complemented by further features like an export function (CSV, XLS and PDF export) and comfortable menus that help users to select the data they are interested in.

Besides giving the presentation (please find it below), I demonstrated the software successfully If you are keen to see the application in action yourself, please visit our demo deployment.

In a joined effort of the 52°North Sensor Web and Semantics communities, we have developed a new framework that enables the plug & play of sensors with the Sensor Web based on Semantic Web technologies. The design of the developed architecture got just published in a journal article.

The developed framework includes mechanisms for the automated semantic mediation between characteristics advertised by new sensors and the defined requirements of sensor web services. The semantic mediation framework is combined with (i) our Sensor Bus, a publish/subscribe architecture to establish message-driven communication between sensors and services, and (2) the 52°North interpreter for Sensor Interface Descriptors, used as a generic driver mechanism for sensors.

To demonstrate this development, we applied it in an oil spill use case where marine sensors measuring for example water temperature and salinity need to be integrated on-the-fly with a Sensor Observation Service. As the figure below illustrates, the semantic matchings of various sensor / service properties need to be assured before the sensor can be connected with the service.
For being able to “talk” to the utilized sensors, we developed according instances of the Sensor Interface Descriptor model for the different marine sensors using our SID Creator tool.

ifgi’s SWSL group extends the deadline for submissions for the upcoming Integrating Sensor-Web and Web-based Geoprocessing book. The new deadline is July 29, 2011. The idea for the book grew out of the successful ISW workshop held at the AGILE conference in  April.
