Version History of Large Areas 2018 (1:4 500 000)

The 'table__history' is part of a larger dataset collection, which encapsulates information pertaining to the 'Suuralueet 2018', translated to English as 'Major Areas 2018'. The data within this table is sourced from the 'Tilastokeskus' (Statistics Finland) website in Finland, and serves as a historical archive, maintaining a version history of its base table rows.

The table contains various columns, most notably, the '_start_date', '_end_date', and '_row_number' columns. The '_row_number' column signifies the raw data row number from the original data source, and along with the '_start_date', uniquely identifies each row in the table. The '_start_date' represents the date a row was extracted from the data source while the '_end_date' indicates when a new version of the row was recorded. If the '_end_date' is null, it suggests the row is the most recent version.

Several columns within the table hold geographic information, which can be utilized for geospatial data analytics. These columns all start with 'geom_' and include data such as geographic coordinates, presented using the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude.

Additionally, the table contains columns representing the name of the major area in different languages, the unique identifier of the major area, and the year, among others.

In terms of practical applications, the data within this table could be utilized in various ways. For example, it could be used by data analysts to study spatial patterns over time, such as observing changes in major area boundaries. It could also be used to analyze trends in the data over time, considering the table maintains a version history of its base table rows. Furthermore, with the help of geographic coordinates, data scientists could perform geospatial data analytics to study various phenomena related to these major areas.
