Noise Areas in Helsinki Streets and Roads
Click here for a data sample
This table contains data sourced from the website of 'Helsinki Urban Environment Division' in Finland. It provides information on noise areas of streets and roads in Helsinki. The data includes details such as the extraction date, row number, ID, sound pressure level (low), sound pressure level (high), data owner, date of update, geo JSON representation of the geometry, geotext representation of the geometry, type of geometry, centroid of the geometry, x-coordinate of the geometry center, y-coordinate of the geometry center, and the raw geometry data. The table can be utilized in various data analytics tasks such as analyzing noise pollution levels in different areas of Helsinki, identifying high noise exposure zones, studying the impact of noise on urban environments, and conducting spatial analysis on noise areas in the city.
