Click here for a data sample
This table contains data from 'Helsinki City Environment Division' website. The data represents the geographical areas and noise levels of road traffic in Finland. The table provides information about the extraction date, unique row number, identifier, lower and higher decibel levels, data source, last updated date, geographic data in GeoJSON and Geotext formats, geometry type, centroid coordinates, and the geometry itself. The data in this table can be utilized in various data analytics scenarios such as analyzing noise pollution distribution, identifying areas with high noise levels, spatial visualization, and correlation studies between noise levels and other variables in the vicinity of the road traffic areas.
