Road Traffic Noise Survey Data 2012 for Area 01 in Helsinki, FinlandTSV
This table contains data from the 'Helsinki Urban Environment Sector' website, which originates from the country Finland (ISO country code: FI). The table provides information related to noise measurements in road traffic areas. The dataset includes various attributes such as the extraction date, row number, unique identifier, noise levels (in decibels) recorded in low and high ranges, data owner, update date, geographic information in different formats (geoJSON, geotext), geometry type, centroid coordinates (X and Y), and the geometry itself. The data in this table can be utilized for various data analytics purposes, for example, studying noise pollution patterns in specific geographic areas, analyzing the impact of road traffic on noise levels, identifying areas with high noise...
