Road Traffic Noise Study 2017 Area 11 - Road Traffic Noise Study 2017 Area 11 - Road Traffic Noise PolygonsTSV
The table 'avoindatameluselvitys_2017_alue_11_tieliikenne_l_den__meluselvitys_2017_alue_11_tieliikenne_l_denpolygon' contains data from 'Helsinki City Environment Department' in Finland. The table includes various columns such as '_extract_date', '_row_number', 'id', 'db_lo', 'db_hi', 'datanomist', 'paivitetty', 'geom_geojson', 'geom_geotext', 'geom_type', 'geom_centroid', 'geom_center_x', 'geom_center_y', and 'geom'. These columns store information that can be utilized for data analytics purposes, such as analyzing noise levels in road traffic and its relation to geographical locations. Additionally, the table provides data about the data source, including the date of extraction, the data owner, and the date of update. The geographic information such as centroid coordinates and...
Version History of Traffic Noise Study 2017 Area 11 Road Traffic Sound Level in FinlandTSV
This table contains the version history of rows extracted from the 'Helsingin kaupunkiympariston toimiala' website in the country 'Finland' (ISO country code 'fi'). The table records the changes made to the base table rows identified by the 'id' column. Each version of a row is identified by a unique '_row_number' value. The '_start_date' column indicates the extraction date of a row, while the '_end_date' column indicates the extraction date of the next version of the row. If a row is the most recent version, its '_end_date' value will be null. The table also includes other columns such as 'db_lo', 'db_hi', 'datanomist', 'paivitetty', 'geom_geojson', 'geom_geotext', 'geom_type', 'geom_centroid', 'geom_center_x', and 'geom', which contain various data related to the extracted rows.
