Historical Versioning of Municipalities 2022 (Scale 1:1 000 000)

The 'table__history' is a unique resource that compiles version history data of its base table rows, part of the 'tilastointialueet_kunta1000k_2022' collection. The table primarily focuses on geographic information, particularly beneficial for geospatial data analytics. It provides a detailed account of various geographic features, such as polygons and multipolygons, along with their centroid points and center coordinates, all expressed through the WGS 84 coordinate reference system, with longitude preceding latitude.

The table also contains information about different areas ('kunta'), denoted with a unique identifier, alongside their respective names presented in various languages. This table also records the year ('vuosi') related to each entry.

A unique feature of this table is the provision of a version history for each row. The '_start_date' and '_row_number' together provide a unique identifier for each row's version, with '_start_date' specifying the date when the row was extracted from the data source. When a new version of a row is extracted, the '_end_date' column captures this date. If the '_end_date' column is null, it indicates that the row is the most recent version.

The data in the 'table__history' can be utilized in multiple ways for data analytics. For instance, geospatial analysts could use the geographic data to study regional trends or patterns over time, thanks to the version history. City planners might use the data to track changes in geographic boundaries, enabling them to plan infrastructure better. Analysts working for language services could use the multilingual place names to ensure accurate translation and localization of content.

This table is sourced from the 'Tilastokeskus' website, a statistical resource from Finland. This underlines the table's credibility and reliability as a data source for comprehensive and diverse analytics.
