NOISE MAPPING IN LARGE URBAN AREAS

The technical aspects of large urban noise maps are discussed in three parts: 1. Strategies for the post-processing of GIS data including the closing of open polygons, defining the heights of buildings, including the use of airborne laser scanning (based on a pilot study in the German town of Bonn) and other techniques to improve the usability of available data; 2. Improving the speed of calculation by the simplification of geometry and/or changing calculation parameters, such as the handling of reflections, and determining the influence on the subsequent results by the use of statistical analysis using the data from Dusseldorf and Birmingham; 3. Noise exposure analysis utilising geo-referenced address data as used in a pilot study in Birmingham, and the influence of various methods of determining facade noise levels including examples using large scale noise maps.
