Swedish Historical Land Use Changes: Version History

The history table is part of the 'dalarna' dataset collection and it tracks the version history of its base table rows. It is designed to store detailed information on a variety of entities with a particular focus on geographic data. This table has several unique components that allow for in-depth analysis and tracking. Sourced from the 'Lantmäteriet' (The Swedish Mapping, Cadastral and Land Registration Authority) website in Sweden, it provides reliable and up-to-date information.

One of the key features of this table is its ability to track changes over time. Each row in the table is assigned a unique identifier that combines the date of extraction and the row number from the raw data. This allows for precise tracking of when information was added or updated. If a row's end date is null, it signifies that the current version of the row is the most recent one.

The table stands out for its focus on geographic data. The original data is in shapefile format, a commonly used format for storing geographical location and attribute information of geographic features. However, this data has been transformed into a final geographic format for ease of use.

This table could serve a myriad of purposes in data analytics. For example, the geographic data could be used to create detailed maps or to analyze spatial relationships. The version history could be used to track changes in these relationships over time, which could prove invaluable in a wide range of fields, from environmental studies to urban planning. Furthermore, the detailed nature of this table allows for a high level of granularity in analysis, making it a versatile tool for data scientists.
