This table contains data sourced from the website of Helsingin kaupunkiympäristön toimiala, originating from Finland (ISO country code 'fi'). It provides information on tieliikenne (road traffic) noise measurements. The table includes various columns such as '_extract_date', '_row_number', 'tietopalve', 'db_lo', 'db_hi', 'datanomist', 'paivitetty', 'geom_geojson', 'geom_geotext', 'geom_type', 'geom_centroid', 'geom_center_x', 'geom_center_y', and 'geom'. The data in this table can be utilized for various data analytics purposes, such as analyzing noise levels in different areas, identifying noise hotspots, studying noise patterns over time, and investigating the relationship between noise and other variables like data source updating frequency or noise measurements taken at different times of the day.
