Noise Round 4 Airport Agglomeration (Lnight)
This API provides a polygon dataset from Round 4 (2022) strategic noise mapping of airports within agglomerations in Ireland, representing conditions during 2021. Data are structured as noise contours for the Lnight period, with each polygon's dB value indicating the annual average Lnight indicator in decibels for night-time noise exposure. The dataset is published by Ireland's Environmental Protection Agency and supports assessment of aircraft noise impact around agglomeration airports as part of national environmental noise mapping obligations. It is provided as free, no-authentication access geospatial data with national geographic scope.edThis is a polygon dataset of the strategic noise mapping of agglomeration airports for Round 4 (2022), representing the situation during 2021, in the form of noise contours for the Lnight period. The dB value represents the annual average Lnight indicator value in decibels over the night time.…
