Long-term Aerial Photography Plan - Version History Table

The 'plan_flygfoto_langsiktig__history' table is a historical archive, storing version history of its base table rows. This aspect makes it unique as it contains two additional columns compared to its base table, which hold the dates when each row was extracted from the data source and when a new version of the row was extracted, respectively. If the end date column is null, it indicates that the row is the latest version.

This table holds geographic information, which originally comes in a shapefile format - a common format for storing geometric location and attribute details of geographic features. These features could be represented as points, lines, or polygons. However, in this dataset, the geographic information has been converted from the shapefile format into its final geographic format.

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

In terms of data analytics, this table could be highly beneficial. For example, the version history of geographical information could help in studying the changes in land use over time, aiding in urban planning and development projects. The geographic data could be used in creating layers in a Geographic Information System (GIS) for better visualization and spatial analysis. Furthermore, the date columns could be utilized to track the frequency of updates to the geographic data, providing insights into how often changes occur in the geographical features.
