Noise Round 4 Rail National (Lden)
This dataset provides polygon-based strategic noise contours for major national railways, produced under Round 4 of noise mapping (2022) and reflecting conditions during 2021. It covers the Lden (day-evening-night) noise indicator for the Cork, Dublin and Limerick noise agglomerations as well as major railways outside these areas. It is published by Ireland's Environmental Protection Agency as part of national obligations to map and report environmental noise exposure from rail transport across the country's strategic noise mapping programme.This is a polygon dataset of the strategic noise mapping of major railways for Round 4 (2022), representing the situation during 2021, in the form of noise contours for the Lden (day, evening, night) period for Cork, Dublin and Limerick noise agglomerations and the major railways outside of the noi…
