Version History of Index Routes in the SWEREF99 12 00 Coordinate System

The 'indexrutor_sweref_12_00__history' table is a historical record of a larger dataset collection. This history table provides an in-depth version history of its base table rows, allowing users to track changes over time. Each row in the table is uniquely identified by a combination of a start date and a row number, which shows when the row was extracted from the data source and its respective position.

The table includes two additional columns that are not present in its base table: a start date and an end date. These columns indicate when a row was extracted and when a new version of that row was extracted, respectively. If the end date is null, this signifies that the row is the most recent version.

One of the significant attributes of this table is its rich geographic data. Originally in shapefile format, the geographic information has been transformed into a final format for better accessibility and understanding. This geographic data allows for the representation of geographic features such as points, lines, or polygons (areas).

The table's data has been sourced from the website of 'Lantmäteriet' (The Land Survey) in Sweden. It can be used in a variety of data analytics applications. For instance, historical geographic data could be utilized to monitor changes in land use over time or to conduct environmental impact studies. Additionally, the version history could be used to track data accuracy or verify data extraction methods over time, providing a useful tool for data quality assurance tasks.
