RML Mapping: Smarte Strasse: Luftqualität

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

• The main temporal dimension is timestamp (minute granularity); sensor and pollutant are modeled as categorical dimensions, with location taken from dataset context.
• All pollutant concentration columns (e.g., g107_no2, g125_o3) are modeled as separate measures, each with unit µg/m³.
• Auxiliary columns timestamp_text and anfangszeit were dropped because they are redundant or not primary time references.
• A normalized, long-form cube model was adopted using sensor and pollutant as explicit dimensions, avoiding column proliferation.
• DefinedTerm resources were generated for sensor, pollutant, and location dimension values to support hierarchy and reusability.

Dimensions:

• timestamp (temporal) - granularity: minute
• sensor (categorical) - hierarchy: Sensor
• location (spatial)

Measures:

• g107_no2 (µg/m³)
• g107_03 (µg/m³)
• g107_pm25 (µg/m³)
• g125_no2 (µg/m³)
• g125_o3 (µg/m³)
• g125_pm25 (µg/m³)
• g131_no2 (µg/m³)
• g131_o3 (µg/m³)
• g131_pm25 (µg/m³)
