Historical Versioning of Scanned Stretches within Laser Data Collection

The 'Scanned Sections History' table is a part of the 'Outcome Laser Data - Scanned Sections' dataset collection. Originating from the 'Lantmäteriet' (The Land Survey) website in Sweden, this historical table maintains the version history of its base table rows.

The table contains a unique combination of a start date and a row number that uniquely identifies each row in this version history table. A key feature of this table is its ability to track changes in the data over time, thanks to the two additional columns compared to its base table: the start date and the end date. The start date indicates when the row was extracted from the data source, while the end date represents when a new version of the row was extracted. Should the end date be null, this signifies that the row is the most recent version.

From a data analytics perspective, this table could be quite useful. For example, it could be used to track changes in land surveys over time, allowing for the analysis of trends and patterns. Additionally, it could help in identifying any discrepancies or errors in the data, as each version of the data is preserved. Furthermore, by comparing different versions of the same row, one could study the evolution of specific data points, providing valuable insights into the data's dynamics.
