Stevenage, UK, 23 August 2006: Digital mapping and GIS software developer Cadcorp has announced that its Cadcorp SIS – Spatial Information System has been chosen as the basis of a new noise analysis mapping application. Jointly developed in France by the Centre Scientifique et Technique du Bâtiment (CSTB) and the Institut Géographique National (IGN), the new product, known as MITHRA-SIG, was created in response to the technical requirements of European Union Directive 2002/49/EC, relating to the assessment and management of environmental noise.
Sold exclusively by Cadcorp business partner Geomod, MITHRA-SIG integrates the analysis engine of MITHRA with the 3D spatial modelling capabilities of Cadcorp SIS Map Modeller. It enables the user to calculate the noise footprint of an entire community from hundreds of thousands of surveyed points and then to use the 3D geospatial modelling capabilities of Cadcorp Map Modeller to graphically represent the results and to generate a 3D visualisation of the townscape or landscape under investigation. The user is able to ‘walk through’ the model to obtain a clear and definitive view of the noise analysis results.
MITHRA-SIG is suitable for monitoring road, rail and industrial noise levels and is designed for use by local authorities, government agencies and acoustic research offices in statutory noise mapping, for assessing the acoustic impact of future construction projects and for mapping noise from roads and railways.
