Version History of Regions 2017 (1:1 000 000) - Historical Records

The 'table__history' is a rich dataset that contains historical records from the 'Provinces 2017' data collection, sourced from the 'Statistics Finland' (Tilastokeskus) website in Finland. The table encapsulates the version history of its base table, providing a temporal perspective on the geographical data it stores. This information offers a unique blend of temporal and spatial data, making it a valuable resource for various forms of data analytics.

The table comprises columns that store geographical information, such as 'geom_geojson', 'geom_geotext', 'geom_type', 'geom_centroid', 'geom_center_x', and 'geom_center_y'. These columns contain geographic data in various formats, including GeoJSON and Geotext, which can be utilized for geospatial data analytics. The geographical coordinates are based on the WGS 84 coordinate reference system, with longitude presented first, followed by latitude.

Furthermore, the table also maintains records of the province names in multiple languages (e.g., Finnish, Swedish, and English), which could be useful in multilingual data analytics or localization tasks. Each row in the table is uniquely identified by the combination of '_start_date' and '_row_number', with '_start_date' indicating when the row was extracted from the data source, and '_row_number' representing the row's position in the raw data.

In addition, the '_end_date' column provides a timestamp of when a new version of a row was extracted. If the '_end_date' is null, it signifies that the particular row is the most recent version. This version history information can be leveraged in data analytics for tracking changes and trends over time.

For instance, the table could be utilized to analyze spatial changes in the provinces over time, or to perform multilingual analysis of province names. Moreover, the historical data could be used to track the evolution of geographical data, which can be crucial in environmental studies or urban planning.
