Version History of Regional Units 2018 (Scale 1:4 500 000)
The 'table__history' is a historical dataset that encapsulates the version history of its base data. This table is a part of the larger dataset collection, 'tilastointialueet_seutukunta4500k_2018'. It provides a meticulous record of how the data in the base table has evolved over time. This is particularly useful for keeping track of changes and spotting trends, which are crucial in data analytics.
The table includes columns that provide geographic information, which can be exploited for geospatial data analytics. The geographic coordinates are presented using the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude.
In addition to the base table columns, the history table includes two special columns: a start date and an end date. These columns document when a row was extracted from the data source and when a new version of that row was extracted. If the end date is null, this indicates that the row is the most recent version. The table also includes a column that uniquely identifies each row in the history table, formed by a combination of the start date and a row number.
The content of the base table is described as 'Seutukunnat 2018 (1:4 500 000)', which translates to 'Region 2018 (1:4 500 000)'. This suggests that the data could be used for regional analysis of Finland, such as tracking changes in regional boundaries or population shifts over time.
The data for this table is sourced from the website of 'Tilastokeskus' (Statistics Finland) in Finland. Thus, the data could also be used for studies related to Finnish demographics or geography, or for longitudinal studies that require historical data.
Field Descriptions
