Version History of Geographical Elements within the Vasterbotten Collection

The table 'clc12_72h_sv__history' is a historical record that belongs to the 'vasterbotten' dataset collection. As a history table, it contains the version history of its base table rows, which signifies that it has two additional columns compared to its base table, specifically tailored for tracking changes over time. These columns hold the date of extraction and the date of a new version extraction from the data source. The most recent version of a row can be identified by a null value in the latter column. The table also includes a unique identifier for each row, formed by a combination of the date of extraction and the row number.

This table encompasses a variety of data, including geographic information transformed from the shapefile format. Shapefile is a simple, non-topological format for storing the geometric location and attribute information of geographic features, which can be represented by points, lines, or polygons. This table, therefore, can provide a wealth of information on geographic features as well.

The table is sourced from the website of 'Lantmäteriet' (The Land Survey), based in Sweden.

In terms of data analytics, this table could provide valuable insights in a number of ways. For instance, the version history could be used to analyze changes in geographic features over time, potentially revealing patterns or trends. The geographic information could be leveraged to perform spatial analyses or create visual representations of the data. Furthermore, the unique identifier for each row could aid in detecting and handling duplicates, enhancing the quality and reliability of any subsequent analysis.
