2018 Version History of Finnish Postal Areas Extending to Maritime Regions
The 'table__history' is a history table that contains the version history of its base table rows, making it an instrumental part of the dataset collection titled 'postialue_pno_meri_2018'. The data content of the table includes significant information about the Paavo postal code areas (extending to marine areas) in 2018, sourced from the Finnish Statistics Bureau (Tilastokeskus).
The table includes columns that contain unique identifiers for each row, the start date of the row extraction from the source, and an end date that marks when a new version of the row was extracted. If the end date column is null, it signifies that the row is the most recent version.
Geographical data is also a key component of this table. Columns with the 'geom_' prefix house geographic information, which can be leveraged for geospatial data analytics. The geographic coordinates are presented using the WGS 84 coordinate reference system, with axis order longitude first, followed by latitude.
Additional columns provide a wealth of information on postal code areas. This includes details like the name of the area in different languages, the area's postal code, the area's size, and a unique identifier for each object.
In terms of data analytics, this table offers numerous possibilities. For example, the table could be utilized to analyze the evolution of postal code areas over time, given the version history data it contains. The geospatial data can be used to perform geographical analysis or to generate visual representations of the data. Furthermore, studying the variations in the size of the postal code areas could yield insights into urban development trends.
