Both emission and immission values are shown. The fixed emissions Lr,e in [dB(A)] form the basis for determining the permissible immissions as part of noise abatement measures or expansion projects conducted during the day. The actual emissions Lr,e in [dB(A)] were measured based on the actual traffic during the day over the course of one year.","summaries":{"proj:epsg":[2056]},"extent":{"spatial":{"bbox":[[5.96,45.82,10.49,47.81]]},"temporal":{"interval":[["2025-09-18T00:00:00Z","2025-09-18T00:00:00Z"]]}},"license":"proprietary","created":"2024-05-14T13:12:31.203525Z","updated":"2025-12-15T21:00:04.635501Z","links":[{"rel":"self","href":"https://data.geo.admin.ch/api/stac/v0.9/collections/ch.bav.laermbelastung-eisenbahn_emissionen"},{"rel":"root","href":"https://data.geo.admin.ch/api/stac/v0.9/"},{"rel":"parent","href":"https://data.geo.admin.ch/api/stac/v0.9/"},{"rel":"items","href":"https://data.geo.admin.ch/api/stac/v0.9/collections/ch.bav.laermbelastung-eisenbahn_emissionen/items"},{"rel":"alternate","title":"STAC Browser","type":"text/html","href":"https://data.geo.admin.ch/browser/index.html#/collections/ch.bav.laermbelastung-eisenbahn_emissionen"}],"crs":["http://www.opengis.net/def/crs/OGC/1.3/CRS84"],"itemType":"Feature","assets":{}}
