Scottish local authorities designate Air Quality Management Areas where air quality objectives are not being met. The dataset includes both active and revoked AQMAs, with many provided as polygons and some buffered points or lines to create a national polygon layer. Data is provided by local authorities and aggregated by the Scottish Government via SpatialData.gov.scot.
Use Cases
- Mapping pollution exceedance zones based on designated AQMA polygons.
- Analyzing trends in air quality management based on AQMA declaration and revocation dates.
- Assessing the scale of air quality interventions based on whether AQMAs are limited to exceedance areas or cover entire local authorities.
Strengths
- Includes revoked AQMAs with a dedicated 'Date revoked' attribute.
- National schema includes a date of AQMA declaration, though not universally provided.
- Data is consolidated into a national polygon dataset from multiple local authority sources.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Many local authorities do not currently provide the date of AQMA declaration.
