This project is about a tool for displaying data in a 3D context hopefully allowing a better understanding of a phenomenon. The Europa Linked Observation Browser allows users to display observation data coming from Sensor Observation Service structured as Linked Open Data following the Semantic Sensor Network Ontology.
The viewer is able to display at the same time up to 3 variables (i.e wind direction, wind speed, wind temperature) coming form the same SPARQL Endpoint on top of NASA World Wind. The user can query time periods and display the results animated and explore the data.
Inspired by 52 North implementation of OGC's Sensor Observation Service (SOS), we decided to take observation data one step forward and expose it using Linked Open Data. For this purpose, we fill a RDFtriple store semi-automatically with data coming from SOS' GetObservation request using an XSL Transformation partially matching the Semantic Sensor Network Ontology, this way an user or client (i.e Europa observation viewer) can query data seamlessly for analysing and creating interesting visualizations.
