Historical Version Records of Large Areas 2017 (1:1 000 000)TSV
The 'table__history' is a comprehensive data collection that serves as a historical record of its base table, which is a part of the 'tilastointialueet_suuralue1000k_2017' dataset. This history table captures the evolution of information over time, specifically tracking changes in the base table's rows. Each row in this history table is uniquely identified by a combination of the extraction start date and the row number from the raw data source. The table contains a wealth of information, including geographical data, names in different languages, and time-stamp data. The geographical data is particularly rich, including data types such as MultiPolygon and Point, stored in various columns. This geospatial information is represented using the WGS 84 coordinate reference system, which...
