Within the framework of the Environmental Noise Directive (END) 2002/49/CE regarding the assessment and management of environmental noise, cities of more than 100,000 inhabitants are required to generate noise maps in order to define action plans for noise reduction. In both urban and suburban areas, methods to fight against noise pollution take on many forms, for example road resurfacing, acoustic screens, reduced speed limits, traffic deviations, urban development, new public transportation policies, etc.
Noise management is generally split into three distinct tasks:
generating noise maps,
evaluating the effectiveness of current action plans from the population's point of view,
sharing information by publishing noise maps and related analyses.
Tools developed within the context of ENERGIC-OD by CNRS Lab-STICC partner wants to connect these three tasks, thanks to a novel platform named Noise-Planet.
Noise-Planet, OnoMap and NoiseCapture
Noise-Planet (http://noise-planet.org/en/index.html) is a project which aims to provide a global and generic framework dedicated to the collect, the modelisation and the assessment of environmental noise measures.
One of the central component of this project is the OnoMap ("Open noise Map") Spatial Data Infrastructure (SDI). This platform provides all the tools to store, catalog, share and display noise data (collected or modelized), based on common and standardized langages and encoding from OGC.
This topic is available on the EOD Forum. Please feel free to use this Forum, you can comment, ask questions, etc. Our specialists responsible for the App will join in the discussion.
Citizen, public authority, private company, association.
Noise pollution, environment, citizen science.
Remark : note that all the tools used in the OnoMap SDI are free and open-source.
In the meantime, to collect noise measures, CNRS Lab-STICC developed the NoiseCapture Android app. Free and open source, this app aims to put the citizen at the centre of a data acquisition project, and highlights the community's initiatives to involve the public. Here, developers have a solid foundation in previous research and are scientifically rigorous, providing a technical and methodological framework for noise data acquisition via smartphones. Using the NoiseCapture app, the public can capture and share noise data using their smartphones.
One The app is capable of analysing the quality of data captured and rendering the data as standardized maps via Open Geospatial Consortium (OGC) standardized information feeds. NoiseCapture's goals are to:
raise noise pollution awareness,
improve researchers and decision makers' understanding of the spatial distribution of urban noise,
give citizens a sense of pride and ownership of their territory,
bridge the gap between public research and public action,
provide a set of scientifically rigorous, experimentally-tested tools generic enough to be used on any European city.
Consult and get collected data
To consult noise measures in an interactive way, a dynamic map is avalaible at the following address: http://noise-planet.org/en/map.html. Here, users can navigate in the map and get measure’s informations by clicking on a polygon.
Because OnoMap and NoiseCapture have been developed in an open way, collected data are freely and openly (licenced under ODbL) provided to the community thanks to the dedicated platform . Each night, one zip files per country is build with three up-to-date geojson files (points, tracks and area). Currently, contributions are coming from more than 36 countries.
