637 - Noise mapping with GIS - managing uncertainty helps promote quality
Shilton S., Stapelfeldt H.
Abstract
The European Directive 2002/49/EC has presented a requirement for strategic noise mapping across Europe covering tens or hundreds of square kilometres of urban landscape. Increasing GIS functionality is being utilised to capture, store and manage large geo-spatial datasets to be utilised for noise mapping purposes. Recent work on uncertainty in noise mapping has presented an understanding of how the potential errors within these datasets can propagate through to become uncertainties in the calculated noise level. An associated challenge for the bodies responsible for noise mapping is the need to understand what a software tool means when it states 'compliance' with a standard based calculation method. This paper will discuss the need for compliance test cases, the systems currently in place which could use these test cases, some of the issues associated with developing compliance test cases, and lastly propose a methodology whereby the end to end processing of data for loosely coupled noise models with GIS can be tested.
