23 In this context NOA has been developing a real-time fire hotspot detection service for effectively monitoring

24 a fire-front. The technique is based on the use of acquisitions originating from the SEVIRI sensor, on top of MSG-1 and MSG-2 satellite platforms.

25 -->

26 <!-- Since 2007, NOA operates an MSG/SEVIRI acquisition station, and has been systematically

27 archiving raw satellite images on a 5 and 15 minutes basis, the respective temporal resolutions of MSG-1 and MSG-2. -->

28 The acquired data are then annotated using the stRDF model and can be queried using the stSPARQL query language.

29

30 On the left sidebar, some example stSPARQL queries to aquire information on the dataset, are provided.

31 <!--The NOA use case is described in more detail in the VLDB

32 demo paper <a href="http://www.earthobservatory.eu/publications/p2010_manoliskoubarakis_vldb2012-2.pdf">here</a>.
