Version History of Base Table Rows in Västernorrland Dataset Collection

The 'clc12_69f_nv__history' is a history table that forms part of the 'vasternorrland' dataset collection. This table holds a detailed record of the version history of its base table rows, with each row uniquely identified by the combination of its start date and row number.

The table contains a variety of columns including those that record the start and end dates of each row extraction from the data source. The addition of these two columns makes it different from its base table. The start date indicates when a row was extracted, while the end date signifies when a new version of the row was extracted. If the end date column contains a null value, this indicates that the row is the most recent version.

Geographic information is also a key feature of this table, initially stored in the shapefile format. This format is a simple, non-topological method for storing the geographic location and attribute information of geographic features which can be represented by points, lines, or polygons. This geographic information has been transformed into a final format from the initial shapefile format.

The data for this table has been sourced through 'Lantmäteriet' (the Land Survey), a website based in Sweden. This comprehensive collection of data could be put to use in a variety of data analytics applications. For example, one could track the changes in geographic features over time, potentially identifying patterns or trends in environmental changes. Similarly, the data could be used to verify the accuracy of other data sources, or to provide a historical context for current data. Furthermore, it could be used to forecast future changes based on historical trends.
