Version History Table for Area Measurements and Geometric Properties
The table in question is a historical record, which is part of a larger dataset collection. It is sourced from the 'Lantmäteriet' website, based in Sweden. The table holds version history for each of its base table rows, meaning it contains two additional columns compared to its base table to hold timestamps for when a row was extracted and when a new version was added. This feature makes this table unique as it allows for tracking changes over time, offering a timeline of the data evolution.
The table includes a unique combination of a start date and row number to distinctly identify every row. It also captures the date a new version of a row was added. If the end date field is empty, it indicates that the current row is the most recent version.
One of the notable aspects of this table is its geographic data, originally in shapefile format, an established method for storing geometric location and feature attribute information. The geographic data, which can be represented as points, lines, or polygons, has been converted into the final geographic format from the original shapefile format.
This historical table could be highly useful in data analytics. For instance, it could allow analysts to track changes in geographic features over time, providing a rich source of temporal spatial data. It could also be used to verify the accuracy of the current data by comparing it with previous versions. In addition, the unique identifier combination allows for precise data tracking and management, making the table an essential asset for any data management strategy.
Field Descriptions
Name | Data type | Description |
---|---|---|
_start_date | date | Contains the date when the row was extracted from the data source. It is part of a combination with '_row_number' that uniquely identifies each row in this version history table. |
_end_date | date | Contains the date when a new version of the row was extracted from the data source. If its value is null, it signifies that the row is the most recent version. |
_row_number | long | Contains the number of the row in the raw data extracted from the data source. It forms a unique pair with '_start_date' to identify each row in this version history table. |
OBJECTID | long | A unique identifier for each object in the table. |
ID | string | An identifier for each entry in the table. |
CODE_12 | string | A coded value representing a specific category or type of data. |
Area_Ha | double | The area of a geographical feature represented in hectares. |
Remark | string | Field for additional information or comments about the row. |
Shape_Leng | double | The length of the geographical shape represented. |
Shape_Area | double | The area of the geographical shape represented. |
geom_geojson | string | The geographical shape represented in GeoJSON format. |
geom_geotext | string | The geographical shape represented in geotext format. |
geom_type | string | The type of the geographical shape (for example, point, line, polygon). |
geom_centroid | string | The centroid of the geographical shape. |
geom_center_x | double | The x-coordinate of the center of the geographical shape. |
geom_center_y | double | The y-coordinate of the center of the geographical shape. |
