526 - Integrated solutions noise-mapping - GIS
Probst W.
Abstract
GIS Technologies are widely used to administrate and use large amounts of georeferenced data. It is obvious that these sources should be used in noise mapping according to the directive 2002749/EC. There are many possibilities to take advantage of the GIS functionalities in Noise Mapping Projects, and some of them are presented as Case Studies carried out or just in progress. The simplest form is the direct input of GIS data in the noise mapping and calculation program. There are some requirements for this input interface to understand the imported data correctly. An example are patios and otherwise complex building structures, that are part of the polygon surface in the GIS and must be transformed to the polygon-line-logic by the noise mapping software. In the german DIN 45687 a so called QSI format was standardized that allows – or is intended to allow – the exchange of complete models between different software packages. Advantages and shortcomings of this interface are discussed. The largest case study using GIS data is the Noise Mapping England Project (NME). For about 15 large project areas these data have been prepared in a uniform way, have been calculated by different software and the results are reimported to the GIS. The calculation software CadnaA used in all these case studies can be configured as a runtime-module and can be hidden completely under the surface of the GIS. The user of the GIS models an urban area with his familiar tools and then starts the noise calculation. CadnaA performs all calculations and returns the results to the GIS, where they are presented or processed further. Such a complete “merging” of GIS and Noise Mapping Software has been applied in the EU Project GipSyNoise and in the Noise-DataBase Swizerland. Experiences with these projects and related case-studies are discussed.
