Version History of ELY Areas 2015 (1:4 500 000)
The 'table__history' is a history table that keeps track of the version history of its base rows. The table is a part of the dataset collection 'tilastointialueet_ely4500k_2015'. The base table contains data about the ELY-areas in 2015 at a scale of 1:4,500,000. This information is sourced from the 'Tilastokeskus' website, located in Finland.
The data in the table is organized into rows, with each row representing a specific version of the base row. Each row in this table is uniquely identified by a combination of the '_start_date' and '_row_number'. The '_start_date' indicates the date the row was extracted from the data source, while the '_row_number' represents the number of the row in the raw data extracted from the data source. The table also includes an '_end_date' column that indicates when a new version of the row was extracted. If the '_end_date' is null, it indicates that the row is the most recent version.
The table also contains geographic information, represented by columns beginning with 'geom_'. These geographic details can be used for geospatial data analytics. It is important to note that the geographic coordinates are presented using the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude.
The data within 'table__history' provides valuable insights and can be utilized in numerous ways. For example, by analyzing the '_start_date' and '_end_date', one can track the changes in the ELY-areas over time. Additionally, the geographical data can be used to map the ELY-areas and analyze spatial patterns and trends. Moreover, the version history information can be used to restore previous versions of the data, if necessary.
