Noise areas under the Environmental Noise Directive 2012

Noise areas under the 2012 EU Environmental Noise Directive. The data is part of SYKE’s open datasets (CC BY 4.0). Purpose of use: EU reporting and support for noise prevention. For more information: https://geoportal.ymparisto.fi/meta/julkinen/Dokumentit/EUmeluselvitykset2012.pdf The Environmental noise maps datase contains environmental noise maps from 2012. The database is based on the noise assessment report given to the EU in accordance with the Environmental Noise Directive (2002/49/EC). This SYKE’s dataset can be used according to open data license (CC BY 4.0). The dataset is used for reporting on environmental noise and to support noise abatement. The location database is designed and built in SYKE. The data is based on shape files describing noise zones in different noise reports. Shape files have been refined in SYKE before reading their location database. Refining has included, among other things, co-ordination variations, the formation of topology, the elimination of discontinuities between counting areas, and the calculation of new characteristics. The spatial dataset has been developed in the Finnish Environment Institute. The dataset includes environmental noise zones as shape files. The environmental noise zones are initially outlined based on various noise assessments and quality of the data has been improved before merging it with the database. The improvements have included coordinate system changes, creating topology, ensuring the consistency and uninterrupted structure of the noise calculation areas, removing areas smaller than 100 m² and calculation of new feature data.
