A Danish decision-support GIS tool for management of urban air quality andhuman exposures

A new prototype model system named AirGIS has been developed to support loc al authorities in air quality management for big Danish cities. The system is based on the Danish operational street pollution model (OSPM), technical and cadastral digital maps and Danish national administrative databases on buildings, cadastres and populations. It applies a geographic information system (GIS). AirGIS estimates ambient air pollution levels at high tempora l and spatial resolutions. The model system enables mapping of traffic emis sions, air quality levels and human exposures at residence addresses, at wo rkplace addresses and in streets. Mapping and scenario results can be compa red with air quality limits. Impact assessment of traffic air pollution aba tement measures can also be carried out. (C) 2001 Elsevier Science Ltd.
