2016 Regional Administrative Boundaries Version History (Scale 1:1,000,000)
The 'table__history' is a rich and comprehensive historical record of the AVI regions in Finland for the year 2016, as sourced from the Finnish Statistics Bureau, 'Tilastokeskus'. This table, part of the 'tilastointialueet_avi1000k_2016' dataset collection, serves as a version history of its base table rows.
The table provides detailed geographic information about the AVI regions, including the regions' names in various languages, such as English, Swedish, and Finnish. It also provides geographic coordinates and multipolygon data, which can be utilized for geospatial data analytics. The geographic coordinates are presented using the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude.
A unique aspect of this table is its structure for tracking changes over time. Each row in the table is uniquely identified by a combination of a '_start_date' and a '_row_number', the latter indicating the row's position in the data extracted from the source. The '_start_date' signifies when the row was extracted, while the '_end_date' indicates when a new version of the row was extracted. If the '_end_date' is null, it implies that the row is the most recent version.
This historical data can be utilized in various ways for data analytics. For instance, the time-stamped geographical information can be used to analyze changes in Finland's AVI regions over time. Similarly, the multipolygon data can be employed to create vivid geographical visualizations, which can aid in understanding regional changes. The data can also be used to link historical changes in these regions to other temporal datasets, thereby enabling more complex temporal analyses.
