Polygon dataset from Ireland's strategic noise mapping programme, showing rail noise contours for the night-time period (Lnight) under Round 2 mapping. It covers rail lines exceeding the threshold of 30,000 vehicle passages per year, mapped across the Dublin and Cork agglomerations and major routes outside these areas. The contours represent modelled noise levels rather than direct measurements, supporting assessment of rail noise exposure at night in accordance with environmental noise directive requirements. Published via Ireland's national open data portal, data.gov.ie, the dataset is geographically referenced and intended for use in environmental noise analysis and mapping.This is a polygon dataset of the strategic noise mapping of rail, which were identified as those rail exceeding the flow threshold of 30,000 vehicle passages per year, in the form of noise contours for the Lnight (night) period for Dublin and Cork agglomerations and the major roads outside of the...
