Observations Dataset • RDF descriptions of hurricane and blizzard observations in the United States. • The data originated at MesoWest (University of Utah) • Observation types: temperature, visibility, precipitation, pressure, wind speed, humidity, etc.
Sensors Dataset • RDF descriptions of ~20,000 weather stations in the United States. • Observation dataset linked to sensors descriptions. • Sensors link to locations in Geonames (in LOD) that are nearby. weather station • SPARQL Endpoint: knoesis1.wright.edu/ openrdf-sesame/ repositories/ LinkedSensorDataset
Linked Datasets Observation KB Sensor KB Location KB (Geonames) location procedure Example location procedure 720F Thermometer Dayton Airport • Very Large • MesoWest • Dynamic • 20,000+ systems • MesoWest • ~Static • 230,000+ locations • Geonames • ~Static
Sensor Discovery Demo • Discover sensors from queries on named location. • SOS access to sensor descriptions on LOD. • For example: Find all weather stations near Dayton Airport • First, search Geonames for URI of Dayton Airport • Then, search dataset for sensors near location • Demo: knoesis1.wright.edu/ SSW_NEW_BETA
