RML Mapping: Luftqualitätsmessungen Ostluft Thurgau – Stundenwerte

Die hier veröffentlichten Datensätze für die Messstationen Weinfelden und Konstanz stammen aus dem automatischen Messnetz von Ostluft, das kontinuierlich verschiedene Luftschadstoffe (z.B. NO₂, PM₁₀, ...

Mapping Structure

• The columns startzeit and endzeit are mapped as temporal dimensions (timestamp of measurement start/end), while messstelle (station name, spatial), messstationid (station ID, categorical), and indikator (indicator/pollutant, categorical) are mapped as key dimensions.
• The messwert column is mapped as the measure, representing the observed value for each dimension combination.
• No columns were dropped; all provided CSV columns are captured as either dimensions or measures based on their description and usage.
• Each unique combination of temporal, spatial, station, and indicator dimensions forms a single observation; there is no aggregation or hierarchy defined in this mapping, as each row is an atomic observation.
• Code (DefinedTerm) resources are generated for each key dimension value to ensure data normalisation and allow reference via IRIs.

Dimensions:

• startzeit (temporal) - granularity: hour
• endzeit (temporal) - granularity: hour
• messstelle (spatial)
• messstationid (categorical)
• indikator (categorical)

Measures:

• messwert
