Noise Round 4 Rail National (Lnight)
Polygon dataset from the Environmental Protection Agency (Ireland) presenting strategic noise mapping of major railways for Round 4 (2022), reflecting conditions during 2021. It provides noise contours for the Lnight (night-time) period, covering the Cork, Dublin and Limerick noise agglomerations as well as major railway lines outside these agglomerations. The dataset forms part of Ireland's national strategic noise mapping programme, supporting assessment of railway noise exposure at national level.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 Lnight period for Cork, Dublin and Limerick noise agglomerations and the major railways outside of the noise agglomerations.…
