Road Traffic Noise Survey 2012 Area 08 Night-TimeTSV
This table contains data from 'Helsinki City Environment Department', sourced from the country Finland (FI). It provides information related to noise study areas for road traffic during night time. The data includes various attributes such as the extraction date, row number, unique identifier, noise decibels (low and high), data custodian, last updated date, geographical representation in both GeoJSON and Geotext formats, geometry type, centroid coordinates, center point coordinates, and the geometry itself. This table can be utilized for data analytics purposes, such as analyzing noise pollution patterns, determining noise exposure levels, and assessing the impact of road traffic noise on the surrounding environment.
