RML Mapping: Smarte Strasse: Luftqualität Vergleichsmessungen

Das Lufthygieneamt beider Basel (LHA) testet im Projekt «Smarte Strasse» kosteneffiziente Mikrosensoren auf ihre Genauigkeit und Zuverlässigkeit. Der installierte Sensor vom Typ «Nubo» der Firma Sensi...

Mapping Structure

• Dimensions: The primary temporal dimension is timestamp (xsd:dateTime). Station and spatial coverage (Basel-Stadt, Schweiz) are modeled as categorical and spatial dimensions, respectively; station values are normalized and linked to code resources.
• Measures: All pollutant concentration columns (*_no2, *_o3, *_pm25 for each station) are mapped as separate measures with unit µg/m3.
• Skipped columns: timestamp_text and anfangszeit are omitted as they are redundant alternative date encodings to the main timestamp.
• Hierarchy/structure: Station is modeled as a dimension (with schema:DefinedTerm code resources); spatial coverage is static from context, not a CSV column. No advanced hierarchies or aggregations; one observation per measure per row.
• ObservationSet linkage: All generated observations are linked to a central cube:ObservationSet for consistent Data Cube conformance.

Dimensions:

• timestamp (temporal) - granularity: minute
• station (categorical) - hierarchy: station_location
• spatial_coverage (spatial)

Measures:

• a2hard_no2 (µg/m3)
• a2hard_o3 (µg/m3)
• a2hard_pm25 (µg/m3)
• feldbergstr2_no2 (µg/m3)
• feldbergstr2_o3 (µg/m3)
• feldbergstr2_pm25 (µg/m3)
• stjohann2_no2 (µg/m3)
• stjohann2_o3 (µg/m3)
• stjohann2_pm25 (µg/m3)
