Version History of Base Table Rows in the Dalarna Collection
The table in question is a comprehensive history table sourced from the 'Lantmäteriet' (The Land Survey) website based in Sweden. It holds the version history of its base table rows, enabling the tracking of changes over time. This is achieved through two additional columns that signify the start and end dates of when each row was extracted from the data source. A unique characteristic of this table is that each row is distinctly identified by a combination of the start date and row number.
The table also contains geographic information which was originally in shapefile format - a common format for storing geometric location and attribute information of geographic features. This information has since been transformed into a final format for use in this dataset.
In terms of data analytics, this table provides rich potential. For instance, one could track the changes in the geographic features over time by comparing different versions of the same row. This could prove beneficial in environmental studies or urban planning. Additionally, the unique combination of the start date and row number could provide insights into the frequency and timing of updates to the dataset. This could assist in understanding the data collection process itself. Lastly, the geographic information could be used for spatial analysis or to create visual representations of the data, aiding in various fields such as geography, logistics, and even marketing for location-based strategies.
Field Descriptions
