Click here for a data sample
This table contains data from the 'Helsinki city environment sector' website, specifically the 'avoindatameluselvitys_2007_alue_05_raideliikenne_l_denmeluselvitys_2007_alue_05_raideliikenne_l_denpolygon' dataset. 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'. It provides information that can be utilized for data analytics purposes. By analyzing this dataset, one can gain insights into various aspects related to noise levels pertaining to rail traffic within specific areas. This can be valuable for understanding noise pollution patterns, identifying areas with high noise levels, and studying the impact of rail transportation on the surrounding environment. The dataset contains geospatial information represented in different formats such as geojson, geotext, and centroids, enabling geospatial analysis and visualizations. The 'avoindatameluselvitys_2007_alue_05_raideliikenne_l_denmeluselvitys_2007_alue_05_raideliikenne_l_denpolygon' table originates from Finland, which has the ISO country code 'FI'.
