The aim of the project has been to investigate the possibility to use satellite data to estimate the acoustic impedance of ground for use in large-scale noise mapping according to the European directive 2002/49/EC. Satellite processed land cover data have been used to classify different ground types. Field measurements of the acoustic impedance of these ground types have been carried out. The project has been successful in finding reasonable relationships between the acoustic impedance of the ground and the land cover classes. A first example of a ground impedance map has been elaborated. In digital form this map can be used as an additional map layer when carrying out noise mapping using software based on digital maps. The market for such maps is expected to encompass about 10000 consultants and environmental authorities in Europe.
