This table represents the version history of the 'avoindataseutukartta_maankaytto_merialue__seutukartta_maankaytto_merialuepolygon' base table. It contains the extracted rows from the data source provided by 'Helsinki Urban Environment Division' in Finland. The table includes columns such as '_start_date' and '_end_date' indicating the extraction dates of the row versions. Utilizing this table, data analysts can perform various data analytics tasks, such as tracking changes over time, analyzing trends, and understanding the historical evolution of land use in marine areas. By examining the 'maankaytto' and 'mtryhm' columns, analysts can gain insights into the different types of land use and land use categories attributed to each row version. The 'geom_geojson', 'geom_geotext', 'geom_type', 'geom_centroid', 'geom_center_x', and 'geom_center_y' columns provide spatial information and allow analysts to perform spatial analyses and visualizations. The 'geom' column contains geometry data for further geospatial processing. Finally, the 'tietopalve' column may offer additional details related to the data version. This table serves as a valuable resource for understanding the historical changes and characteristics of land use in the marine areas of Finland.
