Map of Metropolitan Area Land Use and Water AreasTSV
This table contains data from the website of 'Helsinki City Environment Department' in Finland. It provides information related to land use and bodies of water. The table includes various fields such as extraction date, row number, object name, object group, geographical coordinates in GeoJSON format, geographical coordinates in Geotext format, geometry type, centroid coordinates, x-coordinate of the center point, y-coordinate of the center point, geometry information, and data service. This data can be utilized in data analytics for various purposes, such as analyzing land use patterns, identifying specific objects or groups, calculating geometric properties, and performing spatial analysis.
Version History of Land Use and Water Areas in the Metropolitan Area MapTSV
This table contains the version history of the rows in the 'avoindataseutukartta_maankaytto_ja_vesistot__seutukartta_maankaytto_ja_vesistotpolygon' table sourced from the website of Helsingin kaupunkiympariston toimiala in Finland. Each row in this table represents a specific version of a row from the base table, with additional columns '_start_date' and '_end_date' indicating the extraction dates. The table can be utilized in data analytics to track changes over time, analyze historical trends, and identify patterns or anomalies in geographic features and their attributes.
