Version History of Base Table Rows from a Swedish Dataset Collection

The 'clc12_72h_nv__history' table, part of the 'vasterbotten' dataset collection, is a historical record of geographical data, sourced from Sweden's National Land Survey (Lantmäteriet). This table provides a version history of its base table rows, thus offering a unique perspective into how the data has evolved over time.

The table is composed of several columns that collectively provide detailed insights into the attributes and geographical features of the data. Two of these columns serve to uniquely identify each row in the table, thus ensuring data integrity and enhancing analytical capabilities.

One column indicates the date the row was extracted from the source, while another captures the date a new version of the row was initiated. If the latter is null, it signifies that the current row is the most recent version. There is also a column that provides the row number in the raw data, further enhancing data traceability.

The geographical information, originally in shapefile format, has been transformed into a final format suitable for analytics. This includes information about geographic features, which could be points, lines, or polygons representing areas.

Given its rich information, this table could be utilized in several ways for data analytics. For instance, it could be used to track changes in geographic features over time, enabling environmental studies or urban planning. The unique identification of each row allows for precise data lineage tracking, critical in data governance and management contexts. Additionally, the version history could provide valuable insights into data trends, anomalies, or patterns, which could inform predictive modeling or machine learning algorithms.
