Demos

1. Wildfire Monitoring: The demo builds on the work in project TELEIOS where satellite images from the MSG/SEVIRI sensor are used to discover wildfire hotspots. In the demo you can pose stSPARQL queries to discover information about these hotspots that has been encoded in stRDF. You can also execute refinement operations that increase the occuracy of hotspot information. More information about the complete application can be found in the papers [1], [2].

2. Semantic classification of scenes in the TerraSAR-X archive of DLR: In this demo we showcase the results of the work on knowledge discovery from satellite images and relevant geospatial datasets done in TELEIOS. In this work the content of patches of images from the DLR TerraSAR-X satellite archive has been determined semi-automatically and it has been captured by a hierarchy of classes modelled as an RDFS ontology. All relevant information has been stored in Strabon and the demo shows ways to correlate it with data from Corine Land Cover, OpenStreetMap and Geonames.

3. Sextant: Browsing and Mapping the Ocean of Linked Geospatial Data: In this demo we present Sextant, a web-based tool that enables exploration of linked geospatial data as well as creation, sharing, and collaborative editing of thematic maps by combining linked geospatial data and other geospatial information available in standard OGC file formats. More information about Sextant can be found in our recent ESWC demo paper [1].

4. SexTant: Visualizing Time-Evolving Linked Geospatial Data: In this demo we present the new version of Sextant which adds to the functionality of the previous system the ability to visualize and explore time-evolving linked geospatial data, as well as to edit "temporally-enriched" thematic maps. More information about Sextant can be found in our recent ISWC demo paper [1].
