Version History of Large Areas 2020 (1:1 000 000) Table

The 'table__history' is a historical data table, part of a larger data collection named 'tilastointialueet_suuralue1000k_2020'. It is sourced from the Finnish 'Tilastokeskus' (Statistics Finland) website, and serves as a version history record of its corresponding base table.

The table carries essential information about the 'Major Areas 2020' (Suuralueet 2020), presented at a scale of 1:1,000,000. It includes geographical details such as multi-polygonal geographic representations, the type of geometry, the geographic centroid, and the x and y coordinates of the geographic center. These geographic details are presented using the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude.

In addition, the table includes columns for the unique identifier of the area, the Finnish and Swedish names of the area, the major area number, and the year. It also includes a special row number column, which together with the start date, uniquely identifies each row in this version history table.

Further, the table holds two additional columns - start date and end date - showing the lifespan of each row's version. The start date indicates when the row was extracted from the data source, while the end date signifies when a new version of the row was extracted. If the end date value is null, it indicates that the row is the most recent version.

This table can be utilized in data analytics in various ways. For instance, the geographic data can be used in geospatial analysis to track changes in major areas over time. The version history could also be utilized in trend analysis to observe how the data evolved. Furthermore, the bilingual names of the areas can be leveraged in multilingual data studies or in planning regional communications in Finland.
