Version History Table of Geographic and Geometric Data in Skane Dataset Collection

The table in question is a historical record, tracing the evolution of each row in its base table. It essentially serves as a version history log, tracking changes at the row level. Unique identifiers for each row are formed by the combination of the date of extraction and the raw row number from the data source. The table also records the date a new version of a row was extracted. If a row is the most recent version, this will be indicated by a null value in the 'end date' column.

This table is particularly rich in geographic data, which has been transformed from the shapefile format. This format, commonly used for storing the geometric location and attribute information of geographic features, can represent features as points, lines, or polygons.

The data for this table is sourced from the website of 'Lantmäteriet' (The Land Survey) in Sweden. This information can provide valuable insights into land use patterns, property boundaries, and geographical features.

From a data analytics perspective, this table could be utilized in several ways. For instance, it could be used to analyze changes in land use over time, which could inform urban planning or conservation efforts. Additionally, the geographical data could be used to visualize the spread of specific features or properties across a geographic area. The versioning data could also allow for the analysis of trends in data extraction, which could potentially highlight patterns of interest.
