Version History of Maakunnat 2022 (Provinces 2022) at 1:4 500 000 Scale

The 'table__history' is a valuable repository of historical data, part of the 'tilastointialueet_maakunta4500k_2022' dataset group. This table serves as a version history for its base table rows and includes data regarding the administrative regions of Finland, as provided by the Statistics Finland (Tilastokeskus).

This history table contains an array of columns offering a wealth of information. For example, the columns beginning with 'geom_' offer geographic data that can be harnessed for geospatial analytics. These columns contain information about the geographic type, centroid, center coordinates, and geographic text and JSON data. The geographic coordinates are presented using the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude.

Additional columns provide more context about the data, such as the row number, names of the administrative regions in different languages, and the year of the data. The table also includes columns denoting the start and end dates of the data extraction from the source. These particular columns, coupled with the row number, uniquely identify each row in this history table. An interesting characteristic is the end date column; if its value is null, it implies that the row is the most recent version.

This table could be utilized in various ways for data analytics. For example, studying the geographic data could lead to spatial pattern recognition or geographic distribution of regions. The version history of rows could be used to track changes in regional data over time. Additionally, the multilingual nature of the data offers a unique opportunity for comparative linguistic studies across Finland's administrative regions.
