Historical Version Records of Municipalities 2017 (1:4 500 000)

The 'table__history' is a history table that forms an integral part of a larger dataset, and it primarily contains version history of base table rows. It is sourced from the 'Tilastokeskus' website in Finland. The table is enriched with a variety of data columns, each playing a unique role in data analytics.

The table holds a rich collection of geographic data, encapsulated within columns that start with 'geom_'. These columns provide geojson, geotext, and centroid information, as well as the type of geometry and the center coordinates in x and y. This geographic information, presented using the WGS 84 coordinate reference system (longitude followed by latitude), can be particularly useful for geospatial data analytics. For example, one could utilize this data to map out regions, boundaries, or to conduct spatial analysis for geographical trends.

Another notable feature is the table's ability to track the version history of its base table rows. This is achieved through the '_start_date' and '_end_date' columns, which record the dates when a row was extracted from the source and when a new version was extracted, respectively. If the '_end_date' is null, it signifies that the row is the most recent version. The '_row_number' column, serving as a unique identifier, indicates the row's position in the raw data extracted from the source. These columns can be instrumental in analyzing data changes over time, monitoring updates, or backtracking information to a specific date.

The table also contains other columns like 'kunta', 'name', 'namn', 'nimi', and 'vuosi' that provide further information about municipalities in 2017. This could be used, for instance, in socio-economic studies, demographic analysis, or regional planning.

In summary, the 'table__history' is not only a repository of geographical and historical data but also a tool that can help unravel patterns, trends, and insights for various analytical purposes.
