Web-based screening of air pollution in North Rhine-Westphalia using IMMISluft
On behalf of the Landesumweltamt (State Environmental Agency) of North Rhine-Westphalia LANUV a web-based screening of air pollution in main roads in North Rhine-Westphalia had been developed by IVU Umwelt. The system enables communities to input data and evaluate results using a standardised and validated software application made available by federal state authorities. Due to the fact that the input data for the air quality screening are street-related and thus georeferenced, a web mapping client with GIS (geographical information system) functionality had been integrated in order to preserve spatial information for visualisation and give means of digitizing street segments.
The system has been released to the local authorities in North Rhine-Westphalia end of June 2006. Within a few weeks, around 100 cities have registered.
