Tables

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.
Version History of Road Traffic Night Noise Survey (2012) in Area 08, FinlandTSV
This table contains the version history of rows from the 'avoindatameluselvitys_2012_alue_08_tieliikenne_l_yo__meluselvitys_2012_alue_08_tieliikenne_l_yopolygon' base table. It has additional columns '_start_date' and '_end_date' which represent the extraction dates of the rows. The data in this table is sourced from the website of 'Helsinki City Environment Sector' which originates from the country Finland (ISO country code: 'fi'). The table contains various columns related to the extracted data, such as 'id', 'db_lo', 'db_hi', 'datanomist', 'paivitetty', 'geom_geojson', 'geom_geotext', 'geom_type', 'geom_centroid', 'geom_center_x', and 'geom_center_y'. The data in this table can be used for various data analytics purposes, such as analyzing the change in noise levels over time,...
