Version History of AVI Regions 2015 Table (Scale 1:1 000 000)

The table being described is a history table that stores the version history of rows from its base table. The base table content relates to the administrative boundaries in Finland for the year 2015, as sourced from the Finnish statistical agency, Tilastokeskus. The data in the table could be utilized in numerous ways including geospatial data analytics and studying historical changes in administrative boundaries.

The table includes several columns that provide a wealth of information. Unique identifiers for each row version are created by combining two specific columns: one that indicates when the data was extracted and another showing the row number.

Geographical coordinates are captured in several columns that start with 'geom_'. This information is particularly useful for geospatial data analytics. The geographic coordinates are presented using the WGS 84 coordinate reference system, starting with longitude and followed by latitude.

Other columns provide further specific information, such as the name of the administrative region in both Finnish and Swedish, and unique identifiers for each row. The historical data also include information about the size and shape of the administrative areas.

A noteworthy feature of this history table is the inclusion of columns showing start and end dates. This allows for tracking of data extraction times and understanding when new versions of rows are introduced. If the end date column is null, it indicates that the row is the most recent version.

In terms of data analytics, this table's information could be used in various ways. For instance, changes in administrative boundaries over time could be studied. The geographical data could be used to create visual representations of these areas and how they have changed. Furthermore, potential correlations between the size and shape of administrative areas and other regional data could be explored.
