The European Noise Directive 2002/49/EC focuses on noise mapping calculation for large areas. This requirement generates various challenges for noise mapping authorities including: data collection, data post-processing, large volume data management, control of results uncertainty, calculation processing time, result presentation, interaction with public and data maintenance. This paper will address different degrees of integration of GIS and Noise Mapping Software and will provide an overview of approaches successfully employed to address the technical challenges during a number of recent projects, including Manchester and Merseyside for the Noise Mapping England (NME) project, and the set up of a noise mapping and case study model for the area of Freistaat Sachsen (~20,000 km²).
