Version History Records of Base Table Rows in Norrbotten Dataset Collection

The 'clc12_74g_sv__history' table, which is part of the 'norrbotten' dataset collection, is a historical record of its base table rows. Each row in the table is uniquely identified by a combination of a start date and a row number. The table also includes an end date, which specifies when a new version of the row was extracted. If the end date is null, it indicates that the current row is the most recent version. The table also captures geographic information, which is initially in the shapefile format. Shapefiles are a simple way to store the geometric location and attribute information of geographic features, which can be represented by points, lines, or polygons. The geographic data in this table has been transformed from the shapefile format into its final geographic format. The table is sourced from Lantmäteriet (the Swedish Mapping, Cadastral and Land Registration Authority) in Sweden.

In terms of data analytics, the table could be used in various ways. For example, one could track changes in geographic features over time by analyzing the start and end dates of each row version. This could be useful for monitoring environmental changes or urban development. Additionally, the table could be used to generate visualizations of geographic features, providing a visual understanding of the data. Furthermore, the table could potentially be used to validate or improve other geographic data sources, as it contains comprehensive historical records.
