Interoperability and accuracy requirements for EU environmental noise mapping

چکیده
The use of geoinformation in the environmental sector got a new challenge by the commencement of the EU Environmental Noise Directive 2002/49/EG (END) in 2002 and its transposition into German law (§ 47 a-f of Federal Immission Protection Law) in 2005. The EU environmental noise mapping puts high demands on the access, availability and accuracy of numerous thematic and geographical information in 2D, 2.5D, and 3D. A recently conducted study showed, that financial savings in the context of environmental noise mapping of approx. 60% of the total can be reached both by using the appropriate level of geodata accuracy and by the sustainable use of geoinformation in the context of Spatial Data Infrastructures (SDI). Interoperability of standardised web services (OGC, ISO) meets the requirements of a flexible use of geodata for noise mapping tasks. In our contribution, we will discuss how different strategies for environmental noise mapping are facilitated by the consequent application of Spatial Data Infrastructure techniques.

Strategic environmental noise mapping: methodological issues concerning the implementation of the EU Environmental Noise Directive and their policy implications.
This paper explores methodological issues and policy implications concerning the implementation of the EU Environmental Noise Directive (END) across Member States. Methodologically, the paper focuses on two key thematic issues relevant to the Directive: (1) calculation methods and (2) mapping methods. For (1), the paper focuses, in particular, on how differing calculation methods influence nois...
متن کاملAccuracy Assessment of GLM and FDA Models for Land Subsidence Susceptibility Mapping in Semnan Plain
The mechanism of land subsidence and soil deformation is the dissipation of the excess pore water pressure and the compaction of the soil skeleton under the effect of natural or man-made factors. Land subsidence has occurred in more of 300 plains of Iran, and Semnan Plain is one of the most important areas that face to this phenomenon. The aim of current research was land subsidence susceptibil...
متن کاملEnvironmental noise mapping using measurements in transit
Due to the ever increasing level of environmental noise that the EU population is exposed to, all countries are directed to disseminate community noise level exposures to the public in accordance with EU Directive 2002/49/EC. Environmental noise maps are used for this purpose and as a means to avoid, prevent or reduce the harmful effects caused by exposure to environmental noise. There is no co...
